摘　　要：为了研究DEA法在国内某页岩气的脱硫效果和规律，结合页岩气性质和DEA溶液的脱硫特性，建立了DEA法脱硫模型。利用该模型模拟了页岩气DEA法脱硫过程中的吸收塔工作压力和贫液循环量等参数的变化规律，对模拟结果进行分析，结果表明，可适当提高吸收塔工作压力以提高脱酸效果；提高页岩气的进塔温度可有效减少重沸器的工作负荷；吸收塔塔板数对页岩气的脱酸效果有显著影响；DEA溶液的循环量对重沸器负荷的影响很大；质量分数40％～50％的DEA溶液脱酸效果较好。In order to study desulfurization effect and law of DEA desulfurization method in shale gas, a DEA desulphurization model is established, combining with the characteristics of shale gas and DEA desulfurization method. By using this desulphurization model, the process of DEA desulphurization is simulated by changing law of parameters such as absorption tower pressure,lean amine solution circulating volume, and so on, during the process. The results show that desulfurization effect can be improved by increasing the absorption tower pressure appropriately. The workload of reboiler can be effectively reduced by increasing the shale gas temperature. Absorber stage number has a significant influence on desulfurization effect. Lean amine solution circulating volume has a great effect on reboiler workload. DEA solution whose mass fraction arranges from 40% to 50% has a better desulfurization effect.
