blowdown stack การใช้

A blowdown stack can be used to complement a flare stack or as an alternative.
The failure of the blowdown stack to contain hydrocarbons vented from a raffinate splitter led to a catastrophic explosion at the Texas City Refinery ( BP ) in 2005.
A "'blowdown stack "'is a chimney or vertical stack that is used to vent the pressure of components of a chemical, refinery or other process if there is a process problem or emergency.
The hydrocarbons originated from liquid overflow from the F-20 blowdown stack following the operation of the raffinate splitter overpressure protection system caused by overfilling and overheating of the tower contents . " Both the BP and the U . S . Chemical Safety and Hazard Investigation Board reports identified numerous technical and organisational failings at the refinery and within corporate BP.
