Conceptual design of energy-saving stripping process for industrial sour water

Sour water contains ammonia, carbon dioxide, and hydrogen sulfides, producing from oil refining, coking, and coal gasification. To reduce the energy consumption in sour water stripping, a novel process is proposed which integrates with the bottom flashing mechanical vapor recompression heat pump (MVRHP) for treating such wastewater. Here, Aspen Plus™ as a powerful set of chemical process simulation software is utilized to investigate the economy...
