Abstract

An emissions evacuator system that collects natural gas vented from various components of a natural gas compressor system and directs the vented gases to the intake system of a natural gas engine of the compressor system. The evacuator system utilizes vacuum from an intake system of the natural gas engine contained on compressor packages to "suck up" the gaseous emissions from various emission sources on the compressor package. These emissions are rendered inert when combusted in the natural gas engine.

Abstract

Systems and methods are disclosed for conditioning a fuel gas for a gas engine of a multi-stage gas compressor. The system includes a scrubber of the gas compressor, a heat exchanger, a pressure reducing valve, and a pressure vessel. A disclosed method includes causing a stream of gas to flow from the scrubber of the gas compressor to the heat exchanger, adding heat to the gas via the heat exchanger, lowering the pressure of the gas via the pressure reducing valve, providing the gas to the pressure vessel, removing liquids from the gas via a coalescing type filter element of the pressure vessel, and providing the conditioned fuel gas from the pressure vessel to the engine of the gas compressor. The gas is taken downstream from a mist extraction device of the scrubber and the scrubber is part of a last stage of compression in the multi-stage gas compressor.
