Steam Stripping and Batch Distillation for the Removal/Recovery of Volatile Organic Compounds

摘要

Steam stripping and batch distillation are two techniques under investigation by the Hazardous Waste Treatment Branch of the USEPA Risk Reduction Engineering Laboratory. The studies evaluated the application of these methods to aqueous and dilute organic solutions which are currently subject to land disposal restrictions. General design equations which can be used to assess the applicability of steam stripping to achieve a given separation are included. Preliminary results of a pilot-scale steam stripping study with 2-nitropropane are reviewed. General design procedures for batch distillation are also discussed.
