Process for removal of unreacted oil from surfactant slurry

摘要

A process for effectively removing unreacted oil from a surfactant slurry containing the same comprising: continuously feeding steam from one side of a pressure vessel into an anionic surfactant slurry containing unreacted oil in the pressure vessel while maintaining a pressure in the system of at least 5 kg/cm2; and simultaneously discharging the anionic surfactant slurry from the other side of the pressure vessel into a low pressure region to effect vaporization of the unreacted oil from the anionic surfactant slurry.
