Simultaneous Treatment of Industrial Wastewater and Vent Streams
The recent standards of performance for wastewater sources in the Synthetic Organic Chemical Manufacturing Industry (SOCMI), published by the U.S. Environmental Protection Agency (EPA), call for treatment of waste–water containing 500 ppmw volatile organic compounds (VOCs) and operating at flow rates greater than 1.0 liter per minute. There are a number of methods for achieving compliance with the treatment standards for wastewater. Among these is treatment to a VOC concentration of less than 50 ppmw with the removal of total VOC mass from the wastewater stream by 95%. If the wastewater treatment system uses stripping or evaporation, then the unit must be covered and vented to a control device. Emissions from the vent control system must be no greater than 20 ppmw. In this work, a treatment system is designed that would achieve compliance with the published standards. A novel unit operation—thin–film evaporation into a natural gas receiving stream—is used to treat the wastewater stream, while the vapor stream is combusted in a boiler or similar fired unit. The process employs a multimedia approach to minimize total treatment costs.
