Wellhead Compressor Valve Reduces Methane Emissions

Many modulating valves in the gas industry utilize pipeline gas media for actuating valves which often causes problems with greenhouse emissions. CFR40 Part60 subpart 0000 limits the bleed rate for these modulating valves utilizing the media for actuation.

Problem:

An OEM of gas lift compressors was in search of an all electric valve that could eliminate the pneumatic bleed of gases.

LDAR inspections and possible fines for violation of  ISO 15848-1 pushed this OEM to look for an all electric option that would eliminate the gas bleed.

Solution:

Wellhead compressor valve

A product specialist at Assured Automation proposed the V Port 36 Series full port socket weld ball valve along with the B7 Series explosionproof modulating electric actuator.

Both valve and actuator met the hazardous area requirements and provided the durability the customer required.

The units proved a success for the end user which has improved on their well uptime and barrel per day output. They have expanded this system to all their wells and their gas lift system has proven to be a profitable investment for end users.

CBD Oil Basics-Market Outlook and Production

Market Outlook & Production Overview

It is estimated that the global market for cannabidiol (CBD) oil will grow from $967.2 million in 2020 to $5.3 billion by 2025. The global CBD oil market is mainly driven by growing research funding for cannabinoid research, legalization of CBD in various regions and the rising occurrence of chronic diseases and related complications.

Hemp-derived products are the largest segment in the CBD oil products market. CBD oils are primarily used in pharmaceutical, food, cosmetic and other industries. The cosmetic and food industry segments accounts for more than half of the market but over the next few years the pharmaceutical segment is expected to expand significantly.

There are two classifications for the cannabis plant that produces CBD oil: hemp and marijuana

Hemp-derived CBD is sourced from industrial hemp plants, which are grown primarily for their fiber and seeds. Hemp is differentiated from marijuana by its levels of THC, the cannabinoid that possesses intoxicating properties. Under U.S. law a hemp plant must contain no more than 0.3% THC.

Marijuana-derived CBD is extracted from marijuana plants that have thick, lush foliage and flowers that are generally grown and consumed for their intoxicating properties. The U.S. government defines marijuana plants as those which contain more than 0.3% THC. While most marijuana plants contain THC as the predominant cannabinoid, there are several strains of marijuana that are rich in CBD.

Whether CBD is extracted from hemp or marijuana, it remains identical on the molecular level.

Hemp Growing Process 

Farmers breed plants with high concentrations of CBD and low concentrations of THC to comply with the 2018 Farm Bill through seeds or cloning.

Once harvested, the plant is air-dried for three to four weeks before the stems are soaked to make the decortication process easier. Decortication happens before extraction when the fiber of the plant is removed from the stem.

Extraction Process 

The extraction process is the method of turning plant to oil. Various solvents are used to separate cannabinoids into an oily substance.

  • CO2 extraction utilizes carbon dioxide to produce a highly concentrated oil when the gas is put under high pressure in a low-temperature environment. This manipulates the gas into a liquid, which is then passed through the harvested plant materials resulting in the purest oil possible.
  • Ethanol extraction utilizes ethanol, a polar solvent that mixes with water to draw out water-soluble molecules and cannabis compounds. The resulting dark oil is a mixture of cannabis compounds and Chlorophyll, which is later filtered out. Although this filtration step also removes some of the extracted cannabinoids, thus lowering the overall purity of the product.
  • Hydrocarbon extraction utilizes solvents like propane, butane or acetone to extract CBD oil. Although a cheap and easy process, the extracted oil often has a higher concentration of THC, and a lower concentration of CBD. Plus, the possibility for residue is high, which significantly lowers the purity and effectiveness of products.  \

When it comes to quality, CO2 extraction yields the best products, but at a higher cost due to the need for expensive equipment and knowledgeable extractors.

Processing

Decarboxylation comes after the extraction process. Decarboxylation is a simple heating process that most CBD oil products undergo to activate CBD and its benefits for the human body.

The heat activates the Cannabidiolic Acid (CBDA), which subsequently produces CBD that will interact and bind with receptors within the endocannabinoid system.

Purifying

Purification, or winterization, is an optional step of the process that removes excess fatty acids, chlorophyll, and other plant materials.

Low-cost Easy to Use Batch Controller

Automatic Batch Controller
The new ABC-2020 Automatic Batch Controller
featuring the BIG Blinking Blue Button

Overview
Flows.com and Assured Automation announce the release of the ABC-2020 Automatic Batch Controller. It is low cost and extremely simple to use. It works with any meter that has a pulse output and either a valve or pump. The operator simply uses the arrow keys to set the batch volume, then presses the start button. The valve opens or the pump turns on. The meter measures the liquid throughput and reports it to the controller. The controller closes the valve or turns the pump off when the set total is reached. That’s all there is to it!

The controller features the BIG Blinking Blue Button™ which is the Start/Stop Button and also indicates the status of the controller at all times. It blinks every second while a batch is running and 10 times per second when the batch is near completion. It remains lit when the batch has completed and the controller is ready to run another.

Hardware Components
Since the controller, meter, and valve or pump are separate components, the user can tailor the system to best fit their application. This not only allows for the selection of the best components, it also offers the ability to create the ultimate installation by carefully selecting where each component is placed. All wiring will be done with simple thermostat wire.

MeterValveController
These three components create an easy to use batching system

weatherproof box for batch controllerThe controller is a self-contained compact unit that can be set on a desktop or can be easily mounted to a pipe (horizontal or vertical) or wall. If protection from the elements, washdown, or tampering is needed it is available mounted in a NEMA 4 cabinet with a crystal clear, lockable, hinged front panel. All wires connect to the unit with simple push-in connectors — no opening the enclosure or using screw terminals.

remote button for batch controllerA weatherproof remote button is available that serves as another start/stop button and also provides the same indication as the BIG Blinking Blue Button™ that is on the main controller. This can be used as an emergency stop, or as the main start button for repetitive batches where the volume does not need to change. Another application for this button is to allow a customer to start a batch but not change the volume. Programs are available that only allow for one batch to be dispensed using the remote button. Then an authorized person needs to reset the controller on the main ABC-2020 unit.

Firmware/Programming
There are a growing number of standard programs available to choose from for the ABC-2020. The differences between programs revolve mainly around the resolution; which is tied to the pulse rate of the meter: 10 pulses per gallon, 1 pulse per gallon, 1 pulse per 10 gallons, etc. Some programs include a lockout feature that disables the remote start button after a batch completes. Customized programs are also available if needed

Systems and Components
Typical system packages include multi-jet or positive displacement water meters and 12 VDC solenoid or ball valves. For use with a pump, a pump control relay is available and allows this little unit to control a 120VAC pump.

Fugitive Emissions & Valve Regulations

What are Fugitive Emissions?

Fugitive emissions or FEs refer to the unintended release of environmentally harmful gases or vapors from industrial activities or facilities. It is estimated that 51% of these fugitive emissions have been attributed to valves.

In a typical facility most emissions are from valves and connectors, the most prevalent components, which often number in the thousands. Seal or gasket failure due to normal wear or improper maintenance is the major cause of these valve emissions.

Besides contributing to the loss of salable product, fugitive emissions pose a risk to the health and safety of workers as well as to the surrounding communities.

A Short Overview of Fugitive Emission Regulations

In October 1948, the mill town of Donora, Pennsylvania was covered by a toxic smog unintentionally released by the local steel manufacturing facilities.

After 5 days, the toxic gases resulted in the sickening of thousands and death of 20 in the community. Now considered one of the worst air pollution disasters in the nation’s history, the “Donora Incident” demonstrated the need for air pollution control and lead to the creation of the first clean air programs in the US.

In response to worsening industrial pollution the Environmental Protection agency (EPA) introduced the US Clean Air Act, the first federal legislation regarding air pollution control. Since that time increasingly stricter air pollution policies have been implemented at the US Federal and State levels.

Germany also began instituting air pollution control regulations in 1964 titled “Technical Instructions on Air Quality Control” (Technische Anleitung zur Reinhaltung der Luft) commonly referred to as the TA Luft.

During the late 1980s, EPA legislation was amended to include petroleum refineries and chemical processing plants that emit volatile organic compounds (VOC’s) and hazardous air pollutants (HAPs). The agency began conducting audits in hopes that companies would willingly implement emissions reductions.

In order to reduce the emission of fugitive VOCs and HAPs, the EPA instituted Leak Detection and Repair (LDAR) regulations, a system of procedures a facility utilizes to locate and repair leaking components which includes EPA Method 21, a method for determining VOC leaks from process equipment in parts per million. EPA Method 21 pertains to valves, flanges and other connections, pumps and compressors, pressure relief devices, process drains, open-ended valves, pump and compressor seal system degassing vents, accumulator vessel vents, agitator seals, and access door seals.

By the late 1990’s, the EPA determined that many facilities were under-reporting emissions, failing to implement Method 21 sufficiently to meet emission reduction targets.

It was estimated that 40,000 tons of VOCs were being emitted annually from valves of petroleum refineries alone. By the early 2000’s many refineries agreed to implement official LDAR Programs to avoid litigation. 

Fugitive Emissions Valve Standards

When facilities do not meet the EPA’s Clean air requirements, consent decrees are negotiated with the manufacturing facility, typically resulting in the implementation of a formal Leak Detection and Repair (LDAR) program which implements Method 21 valve VOC monitoring.

Currently, It is believed that 80% of fugitive emissions from valves are emitted through the valve stem of linear valves (gates and globes) due to the rising/rotating of the stem through the packing system and the difficulty of proper sealing.

As the EPA continues to refine its standards for the LDAR process there is a push that new valves used in refineries to be certified as “Low E Technology”. The EPA defines a Low E Valve as:

A valve (including its specific packing assembly) or valve packing for which the manufacturer has issued a written warranty that it will not emit fugitives at greater than 100 ppm, and that, if it does so emit at any time in the first five years, the manufacturer will replace the valve

The push for “low Emissions Valves” and “low Emissions Packing” has prompted many standards organizations such as API, ANSI, ISO, MESC, ANSI and TA-Luft to establish valve and packing test standards which assess fugitive emission performance. 

Examples of Fugitive Emissions valve standards:

American Petroleum Institute Standards (API) currently has three valve/packing emissions standards tests.

  • API 622 Type Testing of Process Valve Packing for Fugitive Emissions. This is a test of the valve packing alone.
  • API 624 Type Testing of Rising Stem Valves Equipped with Graphite Packing for Fugitive Emissions. This test evaluates the total performance of the valve, not just the valve packing, The Packing used in an API 624 test must have passed API 622 Requirements.
  • API 641 Type Testing of Quarter-turn Valve for Fugitive Emissions. This is the type test for quarter turn valve designs evaluating low emissions performance over an accelerated life cycle

International Organization for Standardization

According to ISO testing guidelines the test media must be methane and the test method must be EPA’s Method 21. The EPA has determined that methane is the most destructive to the environment.

  • ISO 15848-1:2015 (Type Testing) specifies testing procedures for evaluation of external leakage of valve stem seals (or shaft) and body joints of isolating valves and control valves intended for application in volatile air pollutants and hazardous fluids.
  • ISO 15848-2:2015 (Production Test) specifies test procedures for the evaluation of external leakage of valve stems or shafts and body joints of isolating valves and control valves intended for application with volatile air pollutants and hazardous fluids.

TA Luft -German Technical Guidelines for Air Pollution

  • Guideline VDI 2440 refers to average gas-like emissions for differing gasket systems.

A much less stringent standard compared to ISO 15848, TA Luft only deals with the sealing system of the stem passage with very general testing requirements.

Magnetic Flow Meter Basics

Magnetic Inductive Flow Meters

A magnetic flow meter, also referred to as mag flow meter or magmeter, is a volumetric flow meter that measures liquids or liquid slurries that have a minimum conductivity of 5 µS/cm.  Magnetic flow meters will typically not work with hydrocarbons, distilled water, non-aqueous solutions and non-conductive solutions.

Magnetic flow meters utilize Faraday’s Law of Electromagnetic Induction to determine the velocity of a liquid flowing in a pipe.  Magnetic flow meters consist of a nonmagnetic flow tube, liner, electrodes and electromagnets to generate a magnetic field. In magnetic flow meters, a magnetic field is generated and channeled into the liquid flowing through the pipe.

Operating according to Faraday’s Law, signal voltage (E) is dependent on the average liquid velocity (V) the magnetic field strength (B) and the length of the conductor (D) which in this instance is the distance between the electrodes.

Faraday’s Formula
E is proportional to V x B x D where: 

E = The voltage generated in a conductor
V = The velocity of the conductor
B = The magnetic field strength
D = The length of the conductor

Mag Meter Operation

The liquid flowing through the pipe is the conductor, and electromagnetic coils surrounding the flow tube generate the magnetic field. The signal is sensed by the two electrodes embedded on opposite sides of the flow tube. The flow signal at the electrodes is directly proportional to the flow velocity, the intensity of the magnetic field, and distance between electrodes.

Magnetic flow meters do not require much upstream and downstream straight runs so they can be installed in relatively short meter runs. 

Advantages of using Electromagnetic Flow Meters

The main advantages of using magmeters is that they feature an obstruction-free design with no moving parts which eliminates flow impediment, requires less maintenance and can be used on very large line sizes.  Accuracy over a wide flow range can be as good as ±0.5%

Mag Meter obstruction free flow path and no moving parts

Mag meters perform extremely well in many municipal and processing applications and is the meter of choice for measuring conductive liquids such as water or slurry. Magmeters also have the advantage of being able to measure both very low flows and very high volume flow rates.

Disadvantages of using Magnetic Flow Meters

Magnetic flowmeters are only effective on conductive fluids, and materials such as unmixed hydrocarbons and gases cannot be measured. However, magnetic materials themselves may also present problems, as hydrodynamic effects can alter the normal flow pattern and disturb the velocity rate enough to interfere with operations. Depending on their size and capacity, magnetic flowmeters can be relatively heavy, and those with higher corrosion and abrasion resistance can be expensive.

Typical Industries Where Magnetic Flow Meters are Used

  • Water/Wastewater Industry
  • Brewing, Distilling, and Wine Making
  • Chemical
  • Food and Beverage
  • Power Generation
  • Pulp and Paper
  • Metals and Mining
  • Pharmaceutical
  • HVAC
  • Mining/Mineral Processing

Magnetic Flow Meter Selection

Key questions which need to be considered before selecting a magnetic flow meter

  • Is the fluid conductive or water based?
  • Is the fluid or slurry abrasive?
  • Minimum and maximum flow rate for the flow meter?
  • Minimum and maximum process pressure?
  • Minimum and maximum process temperature?
  • Is the fluid chemically compatible with the flow meter wetted parts?
  • What is the size of the pipe?
  • Is the pipe always full?
  • Do you require an integral display or remote display?
  • Do you require an analog output?

Magnetic flow meters require a minimum medium conductivity for the technology to measure flow. This chart provides a general guideline on conductivity of common media.

Fire-Safe Shut Off Valves for Distillery Application

Problem: A local distillery was directed by their insurance agency to incorporate fire safe shut off valves on their storage tanks to ensure closure of outlet valves to isolate flammable liquids in the event of fire.

Solution:

Fire Safe Shut off Valves

The head brewer at the distillery contacted us as they had successfully used Assured Automation automated valves and flow meters for previous jobs.

An Assured Automation product specialist suggested the use of the FM Fire-Safe Series. These FM approved thermal shut off valves are spring loaded with a thermal link. When the link burns in fire conditions the spring brings the API607 firesafe ball valve to a closed position, preventing the release of flammable liquids which could potentially feed a fire.

FM Fire Safe Series

Having a fire safety shutoff system in place is very important at any facility which deals with flammable liquids or gasses. The Assured Automation FM Fire-Safe Thermal and Electro-Thermal Emergency Shutdown Valve assemblies are constructed to automatically close or open and mitigate any conditions which could be deemed potentially dangerous.

Both the ball valve and butterfly valve designs are Factory Mutual (FM) approved. Thermal valves have thermal links which operate the valve at a predetermined temperature. The electro-thermal valve adds an electro-thermal link which can be triggered by a low power electrical current impulse, such as a smoke detector alarm. Both valve designs can also be operated manually without affecting the viability of the link.

The FM Fire-Safe valves are the perfect choice when the flow of hazardous liquid or gas needs to be completely halted due to the presence of fire. The valves can also be implemented in fire suppression systems, to release fire retardant in an isolated area instead of the entire plant.

3-piece Ball valve designs are available in sizes from 1/2 to 6”; thermal activation temperatures from 165 to 360° F; threaded, socket weld, butt weld, and flanged connection configurations. Butterfly valves are available in sizes from 2” to 12”; thermal activation temperatures from 165 to 360° F; carbon steel or 316 stainless steel.
