Systems and methods for reducing hydrocarbon gas emissions include the use of an emissions control system connected to a transfer station on a gas pipeline. The transfer station can be a pig launcher or a pig receiver. The emissions control system includes a transfer tank connected to the transfer station through a transfer line and a catalytic heater connected to the transfer tank through a catalytic feed line. The methods call for transferring pressurized hydrocarbon gases from the transfer station to the transfer tank, which is sized to accept a rapid transfer of a large volume of hydrocarbon gases from the transfer station. Once the gas transfer operation has taken place, the hydrocarbon gases can be more slowly processed through the catalytic heater from the transfer tank. The process can be repeated until a sufficient volume of hydrocarbon gases have been removed from the transfer station.
