Abstract: A process and apparatus for stripping a gas from a gas-rich liquid. The apparatus includes a desorption unit (10) to desorb a gas from the gas-rich liquid to form a first product stream (13) including the gas and a vapour, and a second product stream (14) including a gas-lean liquid. The desorption unit (10) includes a gas-rich liquid inlet (25), a first product stream outlet, and a second product stream outlet. The apparatus further includes at least one of a membrane condenser (22) and/or a membrane (evaporator 17). The membrane condenser (22) includes a membrane interface (26) permeable to the vapour through which vapour transfers from the first product stream to the gas-rich liquid stream and the membrane evaporator (17) includes a membrane interface (18) permeable to the vapour through which vapour transfers to separate a vapour portion from the second product stream (14), and an outlet for a vapour reduced second product stream.

Abstract: The invention provides a process for regenerating a liquid absorbent, including: contacting the liquid absorbent with a hydrophobic medium, wherein the liquid absorbent includes at least one amine of Formula (I) and degradation product thereof including 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: 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.
