VAPOUR COMPRESSION FOR REGENERATION OF A CAPTURE MEDIUM RICH IN A CAPTURED TARGET GAS

Abstract: a process of regeneration of a capture medium rich in a captured target gas comprising the steps of: heating a target gas rich capture medium comprising an absorbent medium, absorbed target gas and water using thermal energy, thereby facilitating the separation of the absorbed target gas from the capture medium into a gas containing vapour phase and a heated lean capture medium, said gas containing vapour phase comprising the target gas and water vapour having a steam fraction of at least 0.8; compressing at least one of: the gas containing vapour phase; or a vapour phase thermally associated with the gas containing vapour phase, to form a compressed vapour; and using the compressed vapour as a source of thermal energy to heat the target gas rich capture medium.
