Abstract: This invention generally relates to a system and process for recovering fugitive gas emissions, and more particularly, systems and processes for recovering wet and dry gas emissions from reciprocating compressor packing boxes, gas-operated control valves and pumps, and other packing systems that leak under normal operating conditions. The system and process recover fugitive gases from a compressor packing case and pneumatic components by utilizing a backpressure regulator to maintain a positive pressure in the packing case and pneumatic components and then producing a vacuum to capture and transport any fugitive gas emissions. The recovered emissions are then pressurized to meet the pressures necessary to reenter the first stage of the compressor packing case or the compressor fuel gas system.
