Transfer Operations

Transfer operations are the loading of liquid products on the list of HAPs from a transfer rack within the SOCMI chemical manufacturing process into a tank truck or rail-car. The transfer rack includes the total loading arms, pumps, meters, shutoff valves, relief valves, and other piping and valves necessary to load trucks or railcars.

The proposed transfer provisions control transfer racks to achieve a 98% organic HAP reduction or an outlet concentration of 20 ppmv. Combustion devices or product recovery devices can be used. Again, halogenated streams that use combustion devices to comply with the 98% or 20 ppmv emission reduction must vent the emissions from the combustion device to an acid scrubber before venting to the atmosphere.
