A membrane‐assisted solvent extraction (MASX) system coupled to a membrane‐assisted distillation stripping (MADS) system for use in decontaminating ground‐water is evaluated. Volatile organic compounds (VOCs) in the groundwater are extracted in the MASX unit using a sunflower oil solvent. In the MADS unit, VOCs are stripped from the sunflower oil, which is recycled to the MASX unit. Thermodynamic data for the sunflower oil‐water‐VOCs system were measured. The results were used along with published membrane mass‐transfer data to design MASX and MADS modules.
