First Claim
Patent Images
1. An apparatus comprising:
- an inlet separator configured to receive production gas and to separate entrained liquids from the production gas to form a gas lift gas, the inlet separator comprising;
a production gas inlet,a gas lift gas outlet configured to be fluidically connected to a compressor system comprising at least one engine capable of being operated using the gas lift gas as fuel, anda liquid outlet,a first charge vessel, comprising;
a first liquid inlet fluidically connected to the liquid outlet of the inlet separator,a first charge gas valve configured to be fluidically connected to a high pressure gas source in said compressor system and further configured to deliver high pressure gas to drain the first charge vessel when the first charge gas valve is in an open configuration,a liquid outlet fluidically connected to a first dump valve, the first dump valve allowing liquid from the first charge vessel to flow out of the first charge vessel when the first dump valve is in an open position and preventing the flow of liquid from the first charge vessel when the first dump valve is in a closed position, anda gas outlet configured to be fluidically connected to the at least one engine.

Abstract
The present disclosure provides methods and apparati for separating liquids from production gases and recovering the liquids. The methods and apparati of the present disclosure can reduce or eliminate emissions compared to standard methods and devices and also eliminate the need for haul away of liquids by collecting compressor system liquids in charge vessel(s). The methods and apparati of the present disclosure can also be used to fuel the engines which operate the compressor systems using gas from the compressor drains and the gas used to drain the charge vessel(s).
