Simulation And Optimization Of Coal Indirect Liquefaction Process

In future energy's structure,the new energy system based on coal gasification will play a more and more important role undoubtedly.Coal to Liquid,as a green chemistry technology,has a great significance for adjustment on chinese energy structure,improving entironmental building and the advancement of human society.This work mainly focused on the simulation and optimization of coal indirect liquefaction technology.ASPEN PLUS flowsheet simulation software was used as a main tool.By the study and analyse on ORCF CTL project,a simulation model of coal indirect liquefaction process was developed,including SHELL gaisification model and SMDS Fischer-Tropsch synthesis.In this paper,acrroding to SHELL gasification technology data and ORCF project's design report,the simulation models of gasification were developed,and they were verified by comparing with production data in industry.After completing the simulation models of gasification,the steady state system of SHELL gasification process was developed.The results showed that simulation data was consistant with industrial condition,and this simulation system can be used for later study.Based on this work,the effection on the simulation results were studied by adjusting operating condition,and proposed optimized operating condition.Based on the simulation of coal gasification,this paper using ORCF project's design data simplified the industrial process,adopted slurry bed reactor,and simulated Fischer-Tropsch synthesis.The primary indirect liquefaction products were achieved,and the computer simulation of Fischer-Tropsch synthesis process was developed.
