PROCESS FOR TREATING AN AQUEOUS MEDIUM CONTAINING PHOSPHATE, CYCLOHEXANONE AND CYCLOEXANONE OXIME

摘要

The invention relates to a process for treating an aqueous medium containing phosphate, cyclohexanone and/or cyclohexanone oxime, said process comprising: feeding the aqueous medium to a stripping zone; passing steam through the aqueous medium in the stripping zone; and discharging a vapor stream from said stripping zone; wherein the joint content cyclohexanone and cyclohexanone oxime in the aqueous medium entering the stripping zone is less than 0.08 wt.%.
