Separation of acidic gas constituents from gaseous mixtures containing the same |
摘要 |
Acidic gas constituents are removed from a gaseous mixture by contacting the gaseous mixture with a single-phase liquid solution of a normally liquid dialkyl ether of a polyalkylene glycol and diisopropanolamine. Absorption conditions are selected to effect substantial absorption of the acidic gases while maintaining the solvent as a single-phase. The single-phase liquid solution containing absorbed acidic gases is separated from the resulting sweet gas and conducted to a stripping zone wherein the solution is subjected to conditions to effect removal of absorbed gas therefrom. The resulting stripped single-phase solution can be recycled for further contacting with gaseous mixtures containing acidic gases.
