Process Vents

A process vent is a gas stream that is continuously discharged during the unit operation from an air oxidation unit, reactor process unit, or distillation operation within a SOCMI chemical process. Process vents include gas streams discharged directly to the atmosphere after diversion through a product recovery device. The rule applies only to the process vents associated with continuous (non-batch) processes and emitting vent streams containing more than 0.005 wt % HAP. The process vent provisions do not apply to vents from control devices installed to comply with wastewater provisions. Process vents exclude relief valve discharges and other fugitive leaks but include vents from product accumulation vessels.

Halogenated streams that use a combustion device to comply with 98% or 20 parts per million by volume (ppmv) HAP emissions must vent the emissions from the combustion device to an acid gas scrubber before venting to the atmosphere.
