Abstract
A recovery unit configured to re-inject lost or fugitive emissions back into a pipeline. These configuration may include a pressure vessel that can hold gas (or other fluid) that might vent to atmosphere from, for example, a valve or like flow control. A pump may couple with the pressure vessel. In use, this pump can draw fluid out of the pressure vessel and pressurize it to inject back into the pipeline, typically downstream of the valve. The pump may utilize upstream pressure as a power source.
