NASH Flare Gas Recovery Systems

NASH Flare Gas Recovery Systems

NASH HP and NAB compressors are the ideal choice for recovering fuel gas and condensing valuable hydrocarbons, making more money for the refinery. When reviewing the total life cycle cost of a flare gas compressor system, the NASH liquid ring system provides more value and better reliability than any other technology, hands down. Liquid ring compressors run cool and they clean the gas as they compress it–eliminating the need for downstream aftercondensers and scrubbers. The result is a simpler, more reliable system.

Oil Sealed Packages

Oil Sealed Packages

If you thought you couldn't afford the water costs associated with operating a liquid ring pump…think again.  One of the wonderful features of the liquid ring pump is that it can be operated with a multitude of different fluids. A self-contained oil sealed system has a number of benefits over a traditional water sealed system: It eliminates water usage and disposal costs; it allows you to install it in remote locations where water may not be available; it allows you to attain higher vacuum levels than with water; it can prevent the condensing or dissolving of a process gas; it permits anhydrous processing with a liquid ring pump.

Wellhead Compression Systems

Wellhead Compression Systems

The NASH Vectra XL series of liquid ring pumps was designed to operate as both a vacuum pump and a compressor with a maximum pressure differential of 30 psig.  This allows a negative pressure to be applied to the wells and can: assist in the production of low pressure natural gas and/or remove low pressure gas to aid in the production of oil. The discharge gas can be sent to a high pressure reciprocating compressor for pipeline transport. The systems are built on a platform that can be moved from well to well as needed.
