STEAM STRIPPING INORGANIC PROCESS LIQUID DISCHARGED FROM HPO® EXTRACTION SECTION AND UTILIZING HEAT OF CONDENSATION

摘要

A continuous process for preparing cyclohexanone oxime comprising steps including passing an extracted aqueous phase comprising organic solvent directly from the extraction zone to a water stripping zone; evaporating at least 5 % by weight of the water present in the extracted aqueous phase; passing the water vapour containing stream into a heat exchanger and transferring energy from the water vapour containing stream to an in-process liquid, thereby heating the in-process liquid and condensing at least part of water vapour containing stream.
