CBM – Coal Bed Methane
During the production of natural gas from coal beds water is typically a co-product. Along with the
gas the water is brought to the surface. This water can be very high in sodium, this high sodium
content expressed as the sodium adsorption ratio (SAR) makes the water detrimental to plants, fish
and the environment.
To get the methane out of coal seams water must be continually pumped out. The water contains a cocktail of chemicals including nitrates, nitrites, chlorides and other salts, benzene, toluene, ethylbenzene, other minerals, metals such as arsenic, cadmium , lead and mercury and high levels of total dissolved solids.
The sodium content and other toxic chemicals in the water can be reduced by using ion exchange.
