Abstract
System and methods for recovering flash gas from at least one flash gas source. A system may include a controllable inlet valve having an input in fluid communications with the flash gas source to receive flash gas; a compressor having an input in fluid communications with an output of the inlet valve to receive the flash gas when the inlet valve is open, the compressor compressing the flash gas to form compressed gas; a controllable recirculation valve in fluid communications with an output of the compressor and the output of the inlet valve; and a controller coupled with and selectively controlling the inlet valve and the recirculation valve between i) a pass-through mode wherein the inlet valve is open and the recirculation valve is closed, and ii) a recirculation mode wherein the inlet valve is closed and the recirculation valve is opened. Various embodiments are disclosed.
