Abstract
Apparatuses, systems and methods are shown and described including a system to reduce emissions that includes a reciprocating gas compressor having a plurality of compression spaces and a plurality of throw spaces and an internal combustion engine. The internal combustion engine can have a closed crankcase ventilation system. The plurality of throw spaces are in fluid communication with the closed crankcase ventilation system.
Claims20
A system to reduce emissions comprising:
- a reciprocating gas compressor having a plurality of compression spaces and a plurality of throw spaces;
- and
- an internal combustion engine, the internal combustion engine having a closed crankcase ventilation system, wherein the plurality of throw spaces are in fluid communication with the closed crankcase ventilation system.
A method of capturing emissions comprising:
- communicating the emissions from a plurality of throw spaces of a reciprocating gas compressor;
- and
- combining the emissions with a blow-by gas at a closed crankcase ventilation system of an internal combustion engine.
A system to reduce emissions comprising:
- a reciprocating gas compressor having a plurality of compression spaces and a plurality of throw spaces, wherein the reciprocating gas compressor has a plurality of pistons movable within the plurality of compression spaces;
- an internal combustion engine configured to drive the plurality of pistons of the reciprocating gas compressor;
- and
- a closed crankcase ventilation system in fluid communication with a crankcase of the internal combustion engine and in selective fluid communication with the plurality of throw spaces.
