Reciprocating Compressors
A reciprocating compressor is used to increase the pressure of natural gas in pipelines. Reciprocating compressors vent natural gas from piston rod packing systems during normal operation.

Storage Tanks
Storage tanks are used to hold oil and gas condensate and operate near atmospheric pressure. Gases dissolved in the oil and condensate 'flash' out of the liquid phase. These vapors, rich in methane, may be vented to the atmosphere.
