Abstract

See full text

Techniques are provided for controlling extraction of landfill gas from a landfill. The techniques include obtaining a measure of pressure in the gas extraction system upstream of a flow control mechanism, wherein the measure of pressure is obtained at a point between at least one well and the at least one flow control mechanism. Further, at least one processor may be used to determine that the measure of pressure in the gas extraction system relative to a measure of atmospheric pressure outside of the gas extraction system is not negative. In response to determining that the measure of pressure in the gas extraction system relative to the measure of atmospheric pressure is not negative, the flow rate of landfill gas being extracted from the at least one well is adjusted using the at least one flow control mechanism to achieve a negative pressure in the gas extraction system.
