Treatability studies of condensate water from Synthane coal gasification

Abstract

Bench-scale treatment tests consisting of oil and grease removal, biological oxidation and adsorption with by-product char were conducted on condensate water from the gasification of Montana and Illinois coals in the Synthane process development units. Test data from each of the treatment steps are presented, indicating that a single treatment step will not adequately clean the water and that several consecutive treatment steps will be required. Overall removals of 99.9% phenol and 97% TOC (total organic carbon) were obtained by the treatments used.
