A gas emissions recovery system. The recovery system is designed to receive fugitive gas emissions from a compressor, and pressurize those emissions using a double-acting liquid piston compressor system. The pressurized fugitive gas emissions may be returned to the compressor, or may be injected into a wellbore. The system includes a first liquid piston chamber and a second liquid piston chamber. Each chamber holds an incompressible fluid that is used to force a gas into a fluid reservoir in response to a piston motion of the incompressible fluid. A pump is provided, with the pump being configured to pump the incompressible fluid between the first and second liquid piston chambers and, thereby, induce piston action of the incompressible fluid in the liquid piston chambers. The system includes a processor that controls the cycling of the incompressible fluid in response to signals indicative of liquid levels in the chambers. A method for reclaiming fugitive gas emissions from a compressor is also provided.
