Glycol dehydrators in the natural gas industry have the primary purpose of removing water from an incoming wet gas stream using monoethylene glycol (MEG), diethylene glycol (DEG), or, most commonly, triethylene glycol (TEG).
Compressors are widely used to increase gas pressure for the purpose of pipeline transportation or as a process requirement.
Unstabilized liquids storage tanks in the onshore oil and natural gas sector are used to hold a variety of liquids, including crude oil, gas condensates, and produced water.
Energy and heat generation processes are required throughout the oil and gas value chain.
Leaks are the unintentional releases of natural gas from equipment used in oil and gas operations.
Reciprocating compressors (also referred to as piston compressors), are found in a variety of oil and gas operations.
Reconciliation is the process of comparing source-level (Level 4) inventories with independent site-level measurements to produce Level 5 asset emissions estimates.
When natural gas (NG) is released into the atmosphere, its impact over 20 years as a greenhouse agent is 80 times greater than CO₂.
In natural gas production wells, initial gas flow velocity is usually sufficient to entrain produced liquids as droplets and carry them up the well tubing and to a gas/liquid separator.
