- 摘要：利用Aspen Hysys软件模拟干气脱硫系统的运行过程，考察了操作压力、操作温度、胺液循环量、胺液浓度等条件对干气脱硫后总硫含量的影响，并根据模拟结果进行了优化分析。得到最佳操作条件为：操作温度低于34.00 ℃、贫液流量35.00 t/h、胺液浓度34%~36%、操作压力 1.00~1.10 MPa、贫液中 H2S含量低于 1.20 g/L。最后，提出夏季提高贫液流量和胺液浓度、增加冷却器降低干气温度、结合蒸汽单耗控制再生蒸汽用量等建议，以进一步优化脱硫效果。
Abstract: This article uses Aspen Hysys software to simulate the operation process of the dry gas desulfurization system. Itexamines the impacts of operating pressure, operating temperature, amine solution circulation volume, amine solution concentrationand other conditions on the total sulfur content of the dry gas after desulfurization. Based on the simulation results, an optimizationanalysis is carried out, and the optimal operating conditions are obtained as follows: the operating temperature is lower than34.00 ℃, the lean solution flow rate is 35.00 t/h, the amine solution concentration is 34%-36%, the operating pressure is 1.00-1.10MPa, and the H₂S content in the lean solution is lower than 1.20 g/L. Finally, suggestions such as increasing the lean solution flowrate and amine solution concentration in summer, adding coolers to reduce the dry gas temperature, and controlling the regenerativesteam consumption in combination with the unit steam consumption are put forward to further optimize the desulfurization effect.
