摘要：通过能量衡算分析了高效脱硫溶剂(XDS)的再生塔能耗构成。结果表明,加热胺液所需热量是再生塔再沸器热负荷的主要构成部分,对整个脱硫系统能耗影响最为显著。采用Aspen HYSYS流程模拟分析提高贫液中XDS含量对炼厂气脱硫系统再生塔能耗的影响,并在干气?液化气脱硫装置上进行了工业验证。模拟计算结果表明,提高贫液中XDS含量并降低其循环量可以在保证净化效果的前提下降低再生蒸汽耗量。工业试验结果与模拟值相吻合,贫液中XDS质量分数由23.82%提高到44.40%,再生塔的富液流量和相应的蒸汽耗量可分别降低20.4%和20.6%,节能降耗效果明显;XDS溶剂系统发泡倾向与腐蚀性均维持在较低水平,脱硫系统运行平稳。
The constituent of energy consumption in the stripper for efficient desulfurization solvent （XDS） was analyzed with energy balance. Results suggested that, the energy required to heat amine so- lution accounted for the major part of the reboiler heat duty, and had the most significant impact on the energy consumption of the whole desulfurization system. The effect on reducing energy consumption with increasing the mass fraction of XDS solution for refinery gas desulfurization system was simulated and analyzed by the process simulation software Aspen HYSYS, and then industrial validated in a petro- chemical enterprise. Simulation results showed that, the steam consumption for the stripper could be re- duced by increasing mass fraction of lean solution and reducing solution circulation flow rate under the premise of ensuring the quality of purified gas. Industrial test results matched well with the simulated ones. In the petrochemical enterprise, the mass fraction of lean solution was increased from 23. 820//00 to 44.40G, while the rich solution flow rate and corresponding steam consumption for the stripper could be reduced by 20.4% and 20.6%, respectively, which displayed the positive energy saving effect. Prior and post to increase mass fraction of lean solution, the foaming tendency and corrosive nature of XDS solution kept lower levels, and the desulfurization efficiency of the units remained stable.
