Abstract
A system that can eliminate engine combustion emissions in addition to raw and fugitive methane emissions associated with a gas compressor package. The system may comprise an air system for starting and instrumentation air supply; electrically operated engine pre/post-lube pump, compressor pre-lube pump, and cooler louver actuators; compressor distance piece and pressure packing recovery system; blow-down recovery system; engine crankcase vent recovery system; a methane leak detection system; and an overall remote monitoring system.
Claims20
A system to reduce emissions from a compressor package comprising:
- a. a reciprocating compressor and an engine that drives the reciprocating compressor, wherein at least one of the reciprocating compressor and the engine produce gas emissions;
- b. a blowdown recovery system comprising an external suction line in fluid communication with said reciprocating compressor and an external tank battery such that gas emissions generated by said reciprocating compressor during blowdown events are directed through said external suction line and recycled through the compressor package or directed to the external tank battery;
- and
- c. a monitoring system that monitors key performance indicators and implements an algorithm to identify methane emissions from at least one of said reciprocating compressor and said engine;
- wherein said blowdown recovery system is coupled to said monitoring system,
- wherein said monitoring system actuates real time compressor package adjustments by inputting said key performance indicators into a machine learning model trained using historical operational data and corresponding measured emission data and aid machine learning model outputs predicted emission values based on said key performance indicator.
A system to reduce emissions from a compressor package comprising:
- a. a reciprocating compressor with an engine system that drives the reciprocating compressor, wherein at least one of the reciprocating compressor and the engine emit methane;
- b. an air system comprising an air compressor, said air compressor generating compressed air, and wherein at least a portion of said compressed air is routed to an air dryer and then to a plurality of instrumentation so that said instrumentation is powered by said portion of said compressed air;
- and
- c. a monitoring system that monitors key performance indicators and implements an algorithm to identify system emissions or leaks in said compressor package, wherein at least said air system is coupled to said monitoring system, and wherein said monitoring system is configured to identify system emissions or leaks in at least a portion of said compressor package and provide feedback to instruct system adjustments based on said identified system emissions or leaks.
A retrofit kit to adapt a compressor package comprising an engine system that drives a reciprocating compressor, wherein said compressor package emits exhaust and fugitive emissions, comprising:
- a. a blowdown recovery system comprising an external suction line in fluid communication with said compressor package and an external tank battery such that exhaust and fugitive emissions generated by said compressor package during blowdown events are directed through said external suction line and recycled through said compressor package or directed to the external tank battery;
- and
- b. a monitoring system that monitors key performance indicators and implements an algorithm to identify emissions from said compressor package;
- wherein said blowdown recovery system is coupled to said monitoring system, and wherein said monitoring system actuates real time compressor package adjustments based on said identified emissions or leaks.
