摘　　要：抚顺式油页岩干馏工艺在中国油页岩工业中占据着非常重要的地位,该文利用Aspen Plus软件对该工艺流程进行建模,并通过与实际运行参数进行物料平衡和热平衡数据对比来验证模拟结果的准确性。通过调整送入干馏炉气化段的主风饱和度来分析流程中各段瓦斯流量、组分和热值,以及发电部分的变化情况,并在此基础上分析循环瓦斯温度对系统所产生的影响。研究结果表明,主风饱和度从0℃提高至90℃,系统的循环瓦斯和燃料瓦斯流量将下降近20%,由此用于发电的动力瓦斯流量将大幅提升,使得燃气透平的输出功率从4.07 MW提高至44.12 MW;相对而言,循环瓦斯温度从600℃提高至700℃对系统产生的影响较小,仅将循环瓦斯流量降低了近20%。Fushun-type oil shale retorting system plays an important role in Chinese oil shale industry and the retorting process is simulated by using Aspen Plus software. The results were verified by comparing the material balance and thermal balance with the practical system. Meanwhile, this paper investigated the variation of gas flow, composition, heat value and the power through changing the feeding air＇s saturation. Furthermore, the influence of circulating gas temperature on process was analyzed as well. The results show that feeding air＇s saturation varied from 0 ℃ to 90 ℃ can reduce the circulating gas flow and fuel gas consumption by 20%, and increase the power generation of gas turbine from 4.07 MW to 44.12 MW. However, increase of the circulating gas temperature from 600 ℃ to 700 ℃ has a little effect on process but almost reduces the circulating gas＇ flow by 20%.
