ABSTRACT:
Styrene is removed from a recycle water stream of an ethylbenzene dehydrogenation process by liquid-liquid extraction to prevent polymer buildup on heat exchange tubes and to lower coke formation in boiler tubes. The water stream is then fed into a heater to form steam for use within the reaction zone of the process. The solvent used for the extraction is benzene or a normal paraffin and preferably is the overhead product of a benzene-toluene column which separates the products of the process. The use of extraction lowers utility costs compared to stripping the recycle water stream.
