Process and apparatus for heat integrated liquid absorbent regeneration through gas desorption
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 vapor, and a second product stream (14) including a gas-lean liquid. The desorption u...

Summary: | 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 vapor, 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 vapor through which vapor 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 vapor through which vapor transfers to separate a vapor portion from the second product stream (14), and an outlet for a vapor reduced second product stream. |
