The Basics of Pilot Operated Tank Relief Valves


When liquid is pumped in, storage tanks are pressurized and the current tank vapor is compressed. Tanks are also pressurized owing to higher ambient temperatures that cause the vapor of the tank to expand. Pilot operated pressure relief valves are mounted on tanks to mitigate harm caused by these growing tank vapors to avoid structural harm arising from overpressure.

Here is an outstanding animation, courtesy of Cashco, showing how a relief vent operated by a pilot valve protects a storage tank from overpressurizing during a pump-in condition or during rising ambient temperatures.

US Power Grids, Oil and Gas Industries, and Risk of Hacking


A report released in June, from the security firm Dragos, describes a worrisome development by a hacker group named, “Xenotime” and at least two dangerous oil and gas intrusions and ongoing reconnaissance on United States power grids.

Multiple ICS (Industrial Control Sectors) sectors now face the XENOTIME threat; this means individual verticals – such as oil and gas, manufacturing, or electric – cannot ignore threats to other ICS entities because they are not specifically targeted.

The Dragos researchers have termed this threat proliferation as the world’s most dangerous cyberthreat since an event in 2017 where Xenotime had caused a serious operational outage at a crucial site in the Middle East.

The fact that concerns cybersecurity experts the most is that this hacking attack was a malware that chose to target the facility safety processes (SIS – safety instrumentation system).

For example, when temperatures in a reactor increase to an unsafe level, an SIS will automatically start a cooling process or immediately close a valve to prevent a safety accident. The SIS safety stems are both hardware and software that combine to protect facilities from life threatening accidents.

At this point, no one is sure who is behind Xenotime. Russia has been connected to one of the critical infrastructure attacks in the Ukraine.  That attack was viewed to be the first hacker related power grid outage.

This is a “Cause for Concern” post that was published by Dragos on June 14, 2019.

“While none of the electric utility targeting events has resulted in a known, successful intrusion into victim organizations to date, the persistent attempts, and expansion in scope is cause for definite concern. XENOTIME has successfully compromised several oil and gas environments which demonstrates its ability to do so in other verticals. Specifically, XENOTIME remains one of only four threats (along with ELECTRUM, Sandworm, and the entities responsible for Stuxnet) to execute a deliberate disruptive or destructive attack.

XENOTIME is the only known entity to specifically target safety instrumented systems (SIS) for disruptive or destructive purposes. Electric utility environments are significantly different from oil and gas operations in several aspects, but electric operations still have safety and protection equipment that could be targeted with similar tradecraft. XENOTIME expressing consistent, direct interest in electric utility operations is a cause for deep concern given this adversary’s willingness to compromise process safety – and thus integrity – to fulfill its mission.

XENOTIME’s expansion to another industry vertical is emblematic of an increasingly hostile industrial threat landscape. Most observed XENOTIME activity focuses on initial information gathering and access operations necessary for follow-on ICS intrusion operations. As seen in long-running state-sponsored intrusions into US, UK, and other electric infrastructure, entities are increasingly interested in the fundamentals of ICS operations and displaying all the hallmarks associated with information and access acquisition necessary to conduct future attacks. While Dragos sees no evidence at this time indicating that XENOTIME (or any other activity group, such as ELECTRUM or ALLANITE) is capable of executing a prolonged disruptive or destructive event on electric utility operations, observed activity strongly signals adversary interest in meeting the prerequisites for doing so.”

Variable Area Flow Meters: An Overview

Variable Area Flow Meter
Variable area flow meters, also referred to as Rotameters, have diverse industrial processing applications that range from simple to sophisticated. The devices are easy to install, require no electrical connection, and provide direct flow rate reading. They provide fail-safe flow rate readings in a wide array of industrial applications.

Developed by German inventor Karl Kueppers in 1908, Rotameters measure the volumetric flow rate of liquids and gases. 

Important elements of a variable area flow meter include the tube and the float. Their operation is simple. The tube is fixed vertically and the fluid is fed from the bottom. It travels upward and exits from the top. The float remains at the bottom when no liquid is present and rises upward when fluid enters the tube. 

The float inside the tube moves in proportion to the rate of fluid flow and the area between the tube wall and the float. When the float moves upward, the area increases while the differential pressure decreases. A stable position is reached when the upward force exerted by the fluid is equal to the weight of the float. A scale mounted on the tube records the flow rate of the liquid. Usually, the flow can be adjusted manually using a built-in valve. 

Types of Variable Area Flow Meters 

Variable area flow meters can be categorized by the type of tube they use, which relates to their ability to withstands various pressures, temperatures, process media, and cost. Process connection size and wetted part materials vary as a function the rotameter type and construction. 

Glass Tube Variable Area Flow Meter - The basic glass variable area flow meter consists of borosilicate glass tube while the float is made of either glass, plastic, or stainless steel. The most common combination is a glass tube and metal float. This is suitable for a measure the flow rate of liquid of low to medium temperatures and pressures. 

Applications: Analytical instrumentation; Industrial processes; Chemical production; Pharmaceutical production; Oil & gas extraction; Refining processes; Fuel cell research; Water treatment systems.

Metal Tube Variable Area Flow Meter - Metal tube variable area flow meters are another type that is suitable for temperatures and pressures beyond the physical and mechanical limits of glass tube versions. They are generally manufactured of stainless steel, aluminum, or brass. The piston position is determined by the mechanical and magnetic followers that can be read from the outside of the tube. They are suitable in situations where applications conditions would damage the glass metering tubes, such as steam applications.

Applications: Purge liquid or gas metering; Liquid, gas, or oil flow measurement; Chemical injection; Rotating equipment flow measurement; High-pressure flow meters for offshore oil platforms.

Guided Wave Radar Level Transmitters

Guided wave radar transmitters are widely used across different industries. These devices with their simple installation and trouble-free operations help industrial companies save time and money. They are ideal for a large number of process applications ranging from simple to complex.

How Do Guided Wave Radar Transmitters Work?

Guided wave radar transmitters rely on microwave pulses. Since microwaves are not affected by dust, pressure, temperature variations, and viscosity, this type of transmitter produces highly accurate results.

A low-energy microwave pulse is sent down a probe, and a part of it is reflected back when the pulse hits the process media. The liquid level is directly proportional to the time-domain reflectometry. The time when the pulse is launched and received back is measured to determine the distance from the surface of the media.

Types of Guided Wave Radar Level Transmitters

Guided Wave Radar Level Transmitter
Single Element Design
(NIVELCO)
Guided wave radar level transmitters are available in different probe configurations. Selecting the
right probe is important for successful implementation of the device. While manufacturers offer a range of guided wave radars, most are derived from the three basic probe configurations: single element, twin element, and coaxial.

Single element probe — The single element probe is the most widely used and least efficient device. The device is popular since it is more resistant to the coating of the liquid.

Twin element probe — The twin element probe is a good, general purpose probe that is generally used in long-range applications. They are ideal in situations where flexible probes are important for successful reading.

Coaxial probe — The coaxial probe configuration is the most efficient guided wave radar level transmitters. The probes are used in more challenging low-dielectric applications.

Benefits of Guided Wave Radar Level Transmitters

Guided Wave Radar Level transmitters provide a range of benefits in different applications. The concentration of the measuring signal is strong and clean. This is due to the narrow path of the signal propagation that reduces the chances of impact by stray signals due to obstacles or construction elements inside the tank.

Another benefit of guided wave radar level transmitters is that they are easy to install. No mounting holes are required to install the device. This results in cost savings for the organization. The waveguide can be formed to follow the tank’s contours or mounted at an angle.

The device is ideal in situations where an interface measurement is required. The measuring signals can penetrate the medium deeply, resulting in more accurate results. The waveguide technology is suitable for applications where the medium is subjected to heavy vapors, foam, and dust.

Guided Wave instruments can detect changes in dielectric consents on the boundary of a property. The device can be configured to detect level at both the top and the bottom of a layer of emulsion.

Industrial Application of Guided Wave Radar

Guided wave radar level transmitters are increasingly being used in process industries. The sensors are used in situations that previously employed ultrasonic, hydrostatics, and capacitance. The accuracy specification of the basic model range is up to ±5mm, while the accuracy of the advanced models is up to ±2mm.

The device is generally used in industries to take level readings. The readings are used for local indication and visualization in control systems.

Moreover, guided wave radar level transmitters are also used for managing liquid inventory, determining safety limits, dry run protection, and leak detection. Other applications of guided wave radar level transmitters include communicating low limits to suppliers, automated ordering systems, and streamlining the logistics process.

Guided radar level measurement is also suitable for bulk solids. The surface type is not restricted to liquids since the reflected waves are guided easily through any medium. Foam formation and turbulent liquid surfaces and different angled surfaces (as is the case with bulk solids) don’t influence the accuracy of the reading.

Selection of Guided Wave Radar Level Transmitters

Selection of guided wave radar level transmitters should be based on the requirements of the task. Generally, the rigid single element probe configuration is ideal for angled installations for flowing liquids. The dual flexible wire probe is suitable for most other common applications.

A coaxial probe configuration is recommended for liquids that are cleaner with low dielectric constant and with turbulence on the product’s surface. This type of guided wave radar device is also recommended for installations where the probe is near the tank wall or other obstacles.

Make sure that the device can withstand the range of temperature within the tank. Most GWR devices are rated up to 850 deg F or 450 deg C. You should select a device with added signal strength since this will result in increased reliability and accuracy of the devices.

Guided wave radar level transmitter with dynamic vapor compensation is recommended where a high level of accuracy is required under a high-pressure environment. The measurement taken from the device can compensate for changes in vapor dielectric, which results in improved accuracy.

Other factors that should be considered include mounting and proximity. Single probe configuration can be installed almost anywhere. But the single probe configuration can only to apply to specific situations.

Lastly, the probe length of the device should be of the right length. The length should be according to the measurement rate. This is an important consideration as it can help in ensuring accurate reading with minimum chances of an error.

Guided Wave radar level transmitters can also be used with an agitator. However, certain things must be considered prior to use the device. The probe must be prevented from contacting the agitator blades. Make sure that you confirm the ability of the probe to withstand the force inside the medium. This is important since turbulent on the surface may decrease the accuracy of the measurement. You can install the device in a bypass chamber or stilling well for an agitated tank.

Bridging the Gap between HART Devices and IIoT, the Industrial Internet of Things

Manufacturing Plant of the Future

The typical process control model that involves decision making for the process at the local or centralized level by PLCs (Programmable Logic Controller) or BPCS (Basic Process Control System) is quickly changing. These systems installed yesteryear were never intended to deal with or even realize the amount of data they would have access to in the near future. There are certainly newer ERP, MES and asset management systems that collect some of this data now, but the more critical challenge that local manufacturing facilities face is manpower. Because streamlining of costs and overheads has left many manufacturing facilities with just enough personnel to keep the plant running, facilities no longer have the extra time, personnel and resources required to analyze data. For this reason we are seeing third party companies, and even some of the larger process control vendors, offer leasing or annual agreements that involve collecting, storing, and analyzing all sorts of process data. This data is part of a larger predictive analytics strategy that can not only forewarn operators of impending problems to come, but is also being used to optimize the process itself. This type of cloud automation looks to gather as much data as possible to reduce operating expenditures and future capital expenditures for future plant builds.


So the challenge remains: how do existing and new manufacturing facilities find a cost effective way to get critical plant floor data up to higher level information systems? The answer is to take advantage of the digital HART data you already have installed but either didn’t know it was there or couldn’t afford the equipment upgrades to gain access to it.

This white paper, courtesy of Moore Industries, will outline how the flow of process and diagnostics data from smart HART digital field instruments can now be shared with mid and higher level control, asset management and data information systems without having to upgrade expensive process control interface equipment. Additionally, features and considerations of devices that enable this sharing of data will be reviewed and suggested.

Basics of Industrial Flame Arresters


Flame arresters are a passive devices with no moving parts, engineered to allow hot gas to pass through its body, while stopping a flame, thus preventing a larger fire or explosion.  Flame Arresters uses a wound metal ribbon type element that prevents the spread of flame from the exposed side of the arrester to the protected side of the arrester. The metal element's construction provides a matrix of engineered openings that are carefully calculated and sized to quench the flame by absorbing the flame's heat. As an explosion flame travels through a narrow metal space, heat is transmitted to the walls, energy is lost and only vapor gasses are able to pass through. Flame Arresters are used in many industries such as mining, power generation, petrochemical, chemical,  wastewater treatment, pulp and paper, refining, and pharmaceutical.

Process Weighing Systems Overview

High-accuracy, batch-processing tank
fully supported by KIS Weigh Modules.
In its simplest form, a weigh system consists of a vessel whose contents are to be monitored, load cells or weigh modules that generate a signal proportional to the vessel weight, and an electronic device to power, amplify, interpret and display the signal. However, the accuracy of such a system, while obviously a function of the instrumentation, is also dependent upon the vessel design (reactor, batch tank, inventory silo, etc.), support structure, piping attachments, lateral restraint system, vessel environment (temperature, traffic, nearby equipment), and proper selection of transducer accessories. In short, weigh system accuracy is inexorably tied to the degree of attention given to the mechanical details and vessel functionality.

High accuracy, process weighing systems exhibit system errors under 0.05% for buy-and-sell to 0.25%. Precision load cells or weigh modules with full temperature compensation must be used. To achieve this, the following mechanical requirements are imposed:
  • The weigh vessel must be fully supported by load cells/weigh modules. The number of load cells/weigh modules may vary from one (in tension) to eight (in compression). Generally, as the number of load cells de-creases, the vessel wall thickness and support structure stiffness must increase to carry the higher vessel support reactions lest vessel deformation cause calibration errors.
  • Mechanical restrictions from attached piping and lateral restraints should be avoided. Highly flexible piping attachments are recommended.
  • Hot gas or steam-heating schemes which produce variable buoyancy should be avoided. Consult factory for alternate solutions.
  • Low accuracy inventory weighing systems are those with a system error greater than 0.5%. General purpose cells/ modules are satisfactory for these systems. Mechanical considerations are relaxed considerably:
  • The weigh vessel need only be partially supported by load cells/weigh modules, usually one or two on any side or end of the vessel. This, however, requires the contents to be self-leveling and the vessel itself to be without partitions, so that the load fraction carried by the load cells/ modules is unchanging. (Vessels falling into these two categories must be fully supported, independent of the accuracy required.)
  • Modest mechanical restrictions may be tolerated, but nonlinear mechanical hang-ups or frictional interfaces must still be avoided.
Accuracy Versus Repeatability

Low-accuracy, storage silo partially
supported by KIS Weigh Modules.
Do not confuse system accuracy with repeatability! As long as the mechanical error in a given system is linear with deflection and independent of the environment (temperature, traffic, surrounding vessels, etc.), the inherent system repeatability will be greater than its accuracy. For example, BLH Nobel Transducer Indicators typically have an overall accuracy specification of 0.01% of reading, ±1 count (or better), of which repeatability is but a small fraction. BLH Nobel load transducers, meanwhile, typically display a repeatability of 0.01 to 0.02%. Thus, most BLH Nobel systems will be repeatable within 0.03% of full scale, independent of how the system is calibrated. For most batching operations, repeatability is essential, whereas accuracy (actual pounds used) is of secondary importance once the operating parameters have been established. Field calibration, when required, is generally done by electronic simulation. For buy-and-sell installations, where distribution is by weight, calibration and repeatability are essential; field calibration is always performed employing a dead weight method.

Definitions:
  • Accuracy - Ability of the system to perform weighing functions within an acceptable or desirable tolerance; usually stated as a percentage of either full-scale reading, or ±n count(s) referred to the total number of scale divisions.
  • Repeatability - The ability of the system to read the same value when the measured weight is applied repeatedly in the same manner with the same quantity under constant conditions.
Maximum accuracy and repeatability is obtained by placing high accuracy load cells/modules at all support points and connecting them to instrumentation that measures each cell/module individually.

Selecting the Right Gas Detection Solution

Honeywell gas detection
XNX™ Universal Transmitter
Reprinted from https://www.honeywellanalytics.com. Original article by Don Galman. 

There are many gas detection products on the market that might appear to be the same, but a closer inspection of specification, functionality and features reveals major differences in what products can do and the potential value they can offer. Similarly, individual applications are also unique in their respective designs, needs and processes undertaken.

Know your site risks

Before beginning to consider gas detection equipment, a risk assessment needs to be conducted. Any company employing staff has the obligation to conduct risk assessments to identify potential hazards and these can include potential gas, vapor or Oxygen deficiency risks. If gas hazards are identified, gas detection is applicable as a risk reduction method.

Identifying the prime objective

Depending on the processes being undertaken and the gases being detected, remote or off-site alarm notification plus event data logging/reporting may also be required for Health and Safety management records. Another factor impacting on the need for enhanced reporting functions might be regulatory compliance or a condition of insurance.

Ask the right questions

Having identified the primary objective, the suitable equipment is selected by asking a number of key questions. These fall into three broad categories:

• The gases to be detected and where they may come from

• The location and environmental conditions where detection is to take place

• The ease of use for operators and routine servicing personnel

Identify the gases to be detected and where they may come from

The gases to be detected should be identified by the risk assessment, however experienced gas detection equipment manufacturers and their approved distributors are often able to help in this process, based on their experience of similar applications. However, it is important to remember that it is the end-user’s responsibility to identify all potential hazards.

It is also essential to identify the potential source of a gas release as this helps determine the number and location of detectors required for a fixed gas detection system.

Consider the environmental conditions

Honeywell gas detection
Sensepoint XCD
The performance, accuracy and reliability of any gas detection equipment will be affected by the environmental conditions it is subjected to. Temperature, humidity and pressure levels at the location all have a direct bearing on the type of equipment that should be selected. Additional factors such as potential variations resulting from a production process itself, diurnal/nocturnal fluctuations and seasonal changes may also affect the type of device which is suitable.

Understand product functionality

The next area of consideration relates to additional product functionality. Aspects like wiring configuration are important, especially when retro-fitting into an existing application. If the apparatus is being integrated into a separate safety system, certain communication protocols may also be required such as HART®, Lonworks or Modbus®.

Consideration will also need to be given regarding the requirement for local displays on transmitter units and local configuration of the unit and gas displays may also be a useful addition.

Measure the ease of use for operators and routine servicing personnel

Routine maintenance is another important consideration. Some gases and vapors can be detected with a number of different sensing technologies, e.g. Hydrocarbon gases with catalytic beads or Non-dispersive Infrared NDIR. Catalytic beads do not provide fail-to-safety operation and therefore can require a high frequency of routine maintenance, however NDIR based solutions tend to have a higher initial purchase price, but may require less routine maintenance. In-house resource to undertake such routine maintenance needs to be identified and in the absence of such a resource, budgeting for third party maintenance is an important factor in selecting the right equipment.

Rotating Equipment Condition Monitoring: Critical to Safety, Production, and Profit


Rotating industrial and commercial machinery provides critical and non-critical functions to thousands of manufacturing and processing plants across many industries in the USA.

The detection of changes in a normal vibration pattern is one of several important parameters used to determine equipment deterioration and predict machinery breakdown. The sophisticated monitoring of vibration, along with other machinery operating variables, is known as condition monitoring.

By incorporating an equipment condition monitoring strategy for all your rotating equipment, everything from large large turbine generators to basic production line equipment, operators benefit from the establishment of planned maintenance outages and avoid the very costly down-time resulting from breakdowns and unplanned outages.
