METHODS AND APPARATUSES FOR TREATING AN ORGANIC FEED

摘要

The present subject matter relates to methods and apparatuses for the continuous preparation of a cumene feed for a cumene oxidation process. More specifically, the subject matter relates to a process for passing a cumene alpha-methylstyrene stream through a caustic wash column having an integrated water wash section for the removal of organic acids.

主权项

1. An apparatus for treating an organic feed comprising:
a line for introducing a feed stream from a feed tank containing at least one organic acid compound into a caustic wash section of a caustic wash column; a line for introducing an aqueous caustic scrubbing solution into the caustic wash column; a line for introducing a water stream into a water wash section of the caustic wash column; jetting trays within the column for contacting of the feed through an aqueous caustic scrubbing solution to remove the organic acid from the feed; a line for removing spent aqueous caustic and organic acid solution from the caustic wash column; and a line for removing an organic product from the water wash section of the caustic wash column wherein the organic product has a reduced level of organic acid relative to the feed stream.
