Steam stripping
Steam stripping is a process used in petroleum refineries and petrochemical plants to remove volatile contaminants, such as hydrocarbons and other volatile organic compounds (VOCs), from wastewater. It typically consists of passing a stream of superheated steam through the wastewater. This method is effective when the volatile compounds have lower boiling points than water or have limited solubility in water. References
