摘要:

对空间位阻胺配方溶剂脱除天然气中H₂S和有机硫的性能进行了实验研究,开发出了高效有机硫脱除溶剂CT8-24。室内实验结果表明,CT8-24对H₂S和有机硫的脱除性能明显优于传统的Sulfinol-M溶剂,在相同条件下,对COS脱除率可提高39.3%,对甲硫醇脱除率提高17.4%,净化气中H₂S含量可降低94.1%。针对高含硫气质,采用CT8-24溶剂体系时,溶液循环量与Sulfinol-M溶剂体系相比可降低28.5%,酸气负荷则可提高39%,具有良好的节能降耗效果。

Abstract:

Performances of sterical hindered amine formula solvents for removing H₂S and organic sulfur from natural gas have been studied in laboratory. A high effective organic sulfur removal solvent CT8-24 has been developed. The results show that CT8-24 has higher H₂S and organic sulfur removal capacity than the traditional solvent sulfinol-M. Under the same conditions, the removal rate of COS and RSH could be increased by 39.3% and 17.4% respectively, and the content of H₂S in sweeten gas could be reduced by 94.1% compared with sulfinol-M. Furthemore, when CT8-24 was used in higher sour gas purification, the acid gas loading of the solvent could be increased by 39%, and the solution circulation quantity could be reduced by 28.5%. All above show that the formula solvent has significant effects for saving energy and reducing consumption.
