A Pipeline Gas Blowdown System is used to quickly and safely remove gas from a
blocked-in pipeline section. The Blowdown system allows an operator to quickly remove
the gas from a large section of pipeline for repair or maintenance. The Blowdown
system removes the moisture from the gas and reduces the blowdown noise. A control
valve on the inlet reduces the pressure of gas flow through the high efficiency
separators, and a silencer reduces the exit noise level.
EN-FAB, Inc. has developed a modularized trailer unit for pipeline gas blowdown.
The design provides for:
Reduction of all possible pressures
Measurement of gas flowrate
Separation of gas, liquids, and solids
Reduction of operating noise to a permissible level
Removal of distasteful gas odorants utilizing a deodorizing medium
These trailers are designed for movement along difficult terrain and can be camouflaged
to blend into the surroundings. Trailer design meets local transportation requirements.
The system is designed for portability along the pipeline to selected sites for cleanup,
blowdown, and maintenance requirements.
