Control of Volatile Organic Compounds Emissions from Manufacturing

is equipped with rupture discs having the respective pressure relief
settings. When any of these process vessels are overpressured, the
vapors re1 ieve to the vapor condensi ng/recovery system. By flashi ng

action and by condensation, most of the vapors are condensed, recovered,
and reused in the process. This system a1 so results in a single emission
point in the entire process. Unlike the polyolefins processes, no
flares are used as control devices.
