COST-EFFECTIVE GAS PURIFICATION METHODS AND SYSTEMS BY MEANS OF EJECTORS

The invention provides methods and systems for reducing cost and energy consumption of gas purification processes that use physical or chemical absorbents. These methods and system provide a novel approach to vaporize process energy wastes including thermodynamic inefficiencies and waste heat by optimally integrating ejector technology into gas purification processes. These methods and systems use single-phase and/or two-phase ejectors as alternatives to mechanical compressors or pumps for recirculating fluid between vessels or as part of the cooling system associated to the gas purification processes.
