【摘要】：利用Aspen Plus软件对抚顺式油页岩干馏过程进行模拟,采用带Fortran气化动力学子程序的自定义反应模型来代替Gibbs反应器,通过与文献中实验数据对比来验证模拟结果的准确性,结果吻合良好。利用该模型研究了主风量和主风饱和度等参数对气体组分、气体热值、气化效率和热效率的影响。研究结果表明:随着气化温度的增加,CO的含量增加,而H_2和CH_4的含量减少,同时气体的热值呈现出逐渐降低的趋势;提高主风量,气化效率、干发生气热效率(ηd)和湿发生气热效率(ηw)均有显著提高,但是过量空气的通入将会造成烧油,建议主风量控制在7.38×10~4~8.61×10~4m~3/h最佳;提高主风饱和度,气化温度呈线性下降;当主风饱和度为90℃时,湿发生气热效率(ηw)达到最大,为37.08%;但是综合考虑实际过程中的合理运行,建议主风饱和度选取80℃为宜。
[Abstract]:The Fushun oil shale distillation process was simulated by Aspen Plus software. The self-defined reaction model with Fortran gasification kinetics subroutine was used to replace the Gibbs reactor. The accuracy of the simulation results was verified by comparing with the experimental data in the literature. The results are in good agreement. The effects of main air volume and main air saturation on gas composition, gas calorific value, gasification efficiency and thermal efficiency were studied by using the model. The results show that with the increase of gasification temperature, the content of CO increases, while the contents of HS2 and CH_4 decrease, and the calorific value of gas decreases gradually. The main air volume, gasification efficiency, dry gas thermal efficiency (畏 _ d) and wet gas thermal efficiency (畏 _ w) are all increased significantly, but excessive air flow will lead to oil burning. It is suggested that the main air rate should be controlled at 7.38 脳 10 ~ (4) ~ (4) ~ 8.61 脳 10~4m~3/h. When the main air saturation is 90 鈩，
