专利汇可以提供Liquid-gas absorption process专利检索，专利查询，专利分析的服务。并且Stable alkanolamine-acid gas reaction products formed during the absorption of acidic gases from gas mixtures by means of an alkanolamine-containing absorbent liquid are reverted to free alkanolamines by treatment with caustic and water. The alkanolamines thus formed are recovered from a two phase system and reused in the absorption process.，下面是Liquid-gas absorption process专利的具体信息内容。
2. The method of claim 1 wherein the stable reaction products are concentrated prior to contacting with caustic and water.
3. The method of claim 1 wherein the stable reaction compounds are predominantly oxazolidones.
4. The process of claim 1 wherein the withdrawn alkanolamine phase is steam stripped.
5. The method of claim 1 wherein the absorbent liquid consists essentially of diisopropanolamine, sulfolane and water.
6. The method of claim 4 wherein the stable reaction products are concentrated prior to contacting with caustic and water.
