Method and Apparatus for Eliminating Hydrocarbon Gas Venting from Pneumatic Controllers

Abstract

A method and apparatus which provides the ability to capture natural gas which would otherwise be vented from control valves and use the captured natural gas to power a low pressure pilot light of a burner and/or to power a natural gas engine. In one embodiment, the captured natural gas can be supplemented with an additional supply of natural gas to ensure operation of the pilot and/or natural gas engine in the even that the captured natural gas is not sufficient to provide continuous power of the pilot and/or engine. Optionally, the captured natural gas can be sequestered in a storage vessel.
