Abstract
The invention pertains to processes for separating gases, acid gas, hydrocarbons, air gases, or combinations thereof. The processes may employ using a liquid phase cloud point with or without subsequent liquid-liquid separation. In some embodiments membranes can be employed with reverse osmosis to regenerate a solvent and/or an antisolvent. In some embodiments thermal switching phase changes may be employed during absorption or desorption to facilitate separation.
Claims15
A process for separating gas comprising:
- absorbing one or more gases in a liquid system comprising one or more physical solvents,
- wherein said one or more physical solvents comprise one or more liquid phases in the liquid system;
- and
- changing the number or composition or combination thereof of liquid phases in said liquid system by changing one or more system conditions wherein the temperature of said liquid system is greater than −30° C. and less than 500° C. during the changing;
- desorbing
- at least one gas of said one or more gases;
- and
- reversing said change to the number or composition or combination thereof of liquid phases in said liquid system.
