A method and system for providing heat to a chemical conversion process is advantageously employed in the production of olefin by the catalytic dehydrogenation of a corresponding hydrocarbon. The catalytic dehydrogenation process employs diluent steam operating at a steam to oil ratio which can be 1.0 or below and relatively low steam superheater furnace temperature. The process and system are advantageously employed for the production of styrene by the catalytic dehydrogenation of ethylbenzene.

Method of providing heat for chemical conversion and a process and system employing the method for the production of olefin

A method is provided herein for the extraction of phenol from a waste water stream. The method is used in conjunction with a process for producing acetone and phenol from cumene. The method for extracting phenol from waste water includes contacting in a countercurrent mode a phenol-containing waste water stream with a hydrocarbon stream derived from a bottoms stream from the acetone finishing column to produce a dephenolated waste water stream and a phenol-containing hydrocarbon stream. The phenol-containing hydrocarbon stream is preferably washed with an aqueous caustic solution to provide a hydrocarbon stream, which is then conveyed to the alpha-methylstyrene recovery system. Preferably the hydrocarbon stream derived from the bottoms stream of the acetone finishing column is water washed prior to contacting the phenol-containing waste water stream.
