IMPROVED COMPOSITION AND METHOD FOR ACID GAS TREATMENT |
摘要 |
An improved composition and method for acid gas treatment, comprising an effective amount of tetraethylene glycol dimethyl ether, optionally in combination with other alkyl ethers of alkylene glycols. Utilization of a predominance of tetraethylene glycol dimethyl ether produces significant benefits in carbon dioxide slip in, e.g., ammonia systhesis plants. A solvent based predominantly on tetraethylene glycol dimethyl ether can be used neat or can be added to the existing recirculating solvent stream to increase the concentration of tetraethylene glycol dimethyl ether to a satisfactory level.
