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 NH; and selectively extracting the degradation product into or through the hydrophobic medium.

Process for regenerating a liquid absorbent

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.

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

Process and apparatus for heat integrated liquid absorbent regeneration through gas desorption

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.

Reversible light driven gas absorbent solution and process

An absorption columnfor separating COand a second acid gas from a gas stream, the column comprising a first and second section () for the absorption of COand the second acid gas; a solvent inlet in the second section for the addition of liquid streamincluding an absorbent liquid for COand the second acid gas; a gas inlet () in the first section for the addition of a gas stream () containing COand the second acid gas; a gas outlet () in the second section of the column; a first solvent outlet () for the removal of at least a portion of the solvent () from the second section of the column and a second solvent outlet () for solvent stream () from the first section of the column; and a liquid flow distributor arrangement () to allow a portion of the solvent to flow from the second section of the column to the first section. A method of operating the apparatus and method of solvent extraction is also disclosed.

Process for capturing acid gases

A process for the capture of COfrom gas streams, the process including contacting a COcontaining gas stream with a compound including: a primary or non-sterically hindered secondary amine group and at least one tertiary amine or sterically hindered secondary amine group; wherein the primary or non-sterically hindered secondary amine and the nearest tertiary or sterically hindered secondary amine group are separated by a carbon chain including 3 or 4 carbon atoms and wherein the compound is a compound of Formula (I).
