Abstract: The invention provides a process for regenerating a liquid absorbent, comprising: contacting the liquid absorbent with a hydrophobic medium, wherein the liquid absorbent comprises at least one amine of Formula (I) and degradation product thereof comprising at least one imine of Formula (II), wherein each Ar is independently an aromatic group and each R is independently selected from hydrogen, an organyl group and NH2; and selectively extracting the degradation product into or through the hydrophobic medium.

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.

Abstract: The invention relates to a process for removing a target gas from a gas stream rich in the target gas and to an absorbent solution for absorbing a gas, such as carbon dioxide, from a gas stream. The invention involves the use of a photoactive compound that is convertible from a first state to a second state upon irradiation to facilitate removal or collection of a target gas from a gas stream.
