OPERATING STATUS: Not yet operational.

PROCESS DESCRIPTION: Natural gas from the Altamont field will enter the site through
pipelines. Incoming field gas will be sent through a slug catcher
where free liquids are separated. The free liquids are directed to
a gunbarrel tank where the free liquids are separated into water
and condensate. The separated condensate is directed to two
condensate tanks and is stored to be removed via truck load-out.
The separated water remains in the gunbarrel tank and is
removed through truck load-out. Overhead vapor from the
gunbarrel and condensate tanks is sent to an enclosed combustor.
Overhead gas from the slug catcher is directed to a natural gas
manifold connected to three natural gas-fired compressor
engines. Natural gas for the compressor engines will be provided
by the Altamont Main Gas Plant. Any liquid removed throughout
the compression stages is recycled back to the inlet slug catcher.
Compressed gas is directed to a sulfur scrubbing process. After
treatment, the gas is discharged to the triethylene glycol (TEG)
unit, equipped with a flash tank and still vent condenser, for the
removal of entrained water. Gas from the dehydration unit flash
tank is routed to the facility flare, while still vent condenser
vapors are routed to an enclosed combustor.
