ABATEMENT OF VAPORS FROM GAS STREAMS BY SOLIDIFICATION

摘要

A process for abatement of warm melting point vapors from gas streams (32) is provided. The warm melting point vapors are solidified by direct contact with a chilled liquid (24), and are subsequently removed from the chilled liquid using known separation techniques. The chilled liquid (24) exhibits a vapor pressure at the contacting temperature which is sufficiently low to preclude unsafe levels of the chilled liquid vapor in the processed gas stream (32). The chilled liquid is cooled using indirect heat exchange with a cryogenic liquid and is recycled.
