With concentrations of atmospheric methane increasing twice as fast as carbon dioxide since 1750, methane is the second most impactful greenhouse gas. [2] [3] Efforts taken to reduce the amount of methane in the atmosphere are required to reduce the effects of global climate change. Worldwide methane emissions from agriculture in 2019.
Gas well deliquification, also referred to as "gas well dewatering", is the general term for technologies used to remove water or condensates build-up from producing gas wells. When natural gas flows to the surface in a producing gas well, the gas carries liquids to the surface if the velocity of the gas is high enough.
The decrease in pressure allows methane to desorb from the coal and flow as a gas up the well to the surface. Methane is then compressed and piped to market. The objective is to avoid putting methane into the water line but allow it to flow up the backside of the well (casing) to the compressor station.
The reduction of blowdown by dealkalization keeps the water treatment chemicals in the boiler longer, thus minimizing the amount of chemicals required for efficient, noncorrosive operation. [2] Carbonate and bicarbonate alkalinities are decomposed by heat in boiler water releasing carbon dioxide into the steam.
Methanation is an important step in the creation of synthetic or substitute natural gas (SNG). [7] Coal or wood undergo gasification which creates a producer gas that must undergo methanation in order to produce a usable gas that just needs to undergo a final purification step.

A 40-acre (160,000 m 2) landfill gas collection system with a flare designed for a 600 ft 3 /min extraction rate is estimated to cost $991,000 (approximately $24,000 per acre) with annual operation and maintenance costs of $166,000 per year at $2,250 per well, $4,500 per flare and $44,500 per year to operate the blower (2008). LMOP provides a ...
Fugitive gas emissions are emissions of gas (typically natural gas, which contains methane) to atmosphere or groundwater [1] which result from oil and gas or coal mining activity. [2] In 2016, these emissions, when converted to their equivalent impact of carbon dioxide, accounted for 5.8% of all global greenhouse gas emissions. [2]
