Patent attributes
A control system for controlling extraction of landfill gas, the system comprising: at least one atmospheric pressure sensor configured to measure atmospheric pressure; at least one flow control mechanism disposed in well piping and configured to control flow of the landfill gas through the well piping; and at least one processor configured to perform: obtaining a first atmospheric pressure; obtaining a second atmospheric pressure value; determining whether the second atmospheric pressure value is greater than the first atmospheric pressure value; when it is determined that the second atmospheric pressure value is greater than the first atmospheric pressure value, controlling the at least one flow control mechanism to decrease the flow rate of landfill gas; and when it is determined that the second atmospheric pressure value is less than the first atmospheric pressure value, controlling the at least one flow control mechanism to increase the flow rate of landfill gas.
