Operators often use glycol dehydrators to remove water from natural gas. Triethylene glycol (TEG) dehydrators are the most common dehydrators used in oil and gas operations. In the process, wet gas enters near the bottom of the glycol contactor and comes into contact with lean glycol (water poor) in the contact tower absorber. In the […]
If you’re responsible for operating a gas station or truck stop, you know the importance of having a vapor recovery system in place. But if you’re not in the industry, you may be wondering what a vapor recovery system is and why it’s needed. In this post, we’ll take a closer look at what vapor […]
Renewable natural gas (RNG) is a term used for biogas that has been processed and conditioned for use in place of natural gas produced by oil and gas wells. Biogas results from the decomposition of organic matter under anaerobic (no free oxygen) conditions. Sources of biogas used to produce RNG includes municipal solid waste landfills, […]
The U.S. Environmental Protection Agency (EPA) requires reporting of greenhouse gas (GHG) emissions for all industrial sectors of the U.S. economy. The rules are contained in 40 CFR 98 – Mandatory Greenhouse Gas Reporting. Facilities that have actual calendar year GHG emissions of 25,000 metric tons carbon dioxide equivalent (CO2e) must calculate and report GHG […]
Enclosed combustion devices (ECDs) are frequently used by oil and gas (O&G) operators to reduce methane (CH4) and VOC emissions from natural gas venting. The efficiency of an enclosed combustor is often referred to as the control efficiency or destruction and removal efficiency (DRE). Federal (NSPS OOOOa) and many State environmental regulations require control devices […]
The news is full of new terms to describe efforts to reduce greenhouse gas (GHG) emissions. One term we will be seeing more in the future is net zero carbon. Many publicly traded companies are announcing net zero carbon targets for their operations. Net zero carbon refers to actions taken to offset GHGs emitted into […]
On November 15, 2021, the U.S. Environmental Protection Agency (EPA) published proposed rulemaking regarding methane and VOC emissions from oil and natural gas industries. A main thrust of the rule is to reduce the greenhouse gases (GHG) methane. The proposed rules will affect existing and new Crude Oil and Gas industry operations. For crude oil […]
The U.S. has over 2,600 municipal solid waste landfills (MSWL). These landfills receive household waste such as product packaging, lawn clippings, furniture, clothing, glass bottles, metal cans, food waste, newspapers, appliances, paint, and batteries. This comes from homes, schools, hospitals, and businesses. MSWLs emit landfill gas (LFG) biogas comprised of methane and other nonmethane organic […]
Methane has been getting much bad press lately. Despite all of the bad things projected onto methane there are many aspects and uses of this natural gas making it valuable and important. Using methane as a fuel for electricity and heat generation and feedstock for U.S. chemical and refining processes has resulted in an unprecedented […]
NSPS OOOOa applies to oil and gas facilities constructed, modified or reconstructed after September 18, 2015. The rule controls venting and fugitive emissions of volatile organic compounds (VOCs) and methane from oil and gas production, processing, transmission, and storage sectors. The rule has specific emission control standards for various equipment and processes. The rule also […]
