Abstract

Abstract: In this paper,Aspen Plus was used to simulate Fushun type retort for oil shale processing using a user-defined model with gasification kinetics of Fortran subroutines to replace Gibbs reactor.The accuracy of results was verified by comparing document of the experimental data and simulation of the data,which indicated that the results were in good agreement.Meanwhile,the effects of the air volume as well as saturation of feeding air on the gas component,the calorific value of the gas,the gasification efficiency and the thermal efficiency were systematically studied.The results showed that the increase of gasification temperature could decrease H₂ and CH₄ fractions and promote the generation of CO. Furthermore, the high temperature gasification would lead to a decrease of heating value. The increase of the air volume could raise the gasification efficiency and the thermal efficiency(η_w)as well as the thermal efficiency(η_d). Because the excess air may cause oil firing,it was suggested that the air volume was best in the range of 7.38×10⁴-8.61×10⁴m³/h. The gasification temperature declined linearly when the saturation of feeding air increased. When the saturation of feeding air maintained 90℃,the thermal efficiency(η_w)reached the maximum value of 37.08%.But considering the reasonable operation in the actual process,the saturation of air of 80℃ was recommended.

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H₂和CH₄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（η_d）和湿发生气热效率（η_w）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7.38×10⁴~8.61×10⁴m³/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（η_w）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。
