基于程序驱动的常减压蒸馏-加氢裂化全流程模拟与分析
Process simulation and analysis of atmospheric and vacuum distillation and hydrocracking based on program driving
摘要
Abstract
Objective Being a kind of traditional fossil fuel,petroleum has complex compositions,which makes it difficult to accurately control in refineries.Under the requirements of intelligent manufacturing,establishing a reasonable and reliable refining process model and accurately predicting the impact from upstream and downstream during the refining process can help achieve intelligent regulation and optimization of the refining process.Methods Based on Aspen HYSYS software and the reactor module integrated with lumped kinetic model,a rigorous simulation process of atmospheric and vacuum distillation-hydrocracking from crude oil to product was established.Based on the simulation,the influence of the volume ratio of hydrogen-containing gas to oil on the reaction products flow rate and the amount of hydrogen was investigated.On this basis,the change of product output of downstream hydrocracking unit was obtained by using Matlab to drive process simulation under the condition of fluctuation of upstream crude oil ratio.Results The simulation had high accuracy,with an average relative error of 0.41%.When the proportion of domestic crude oil increased from 20%to 50%,the production of diesel products decreased by 13.9%,the production of naphtha products increased by 6.1%,and total production decreased by 8.7%.Conclusions Based on the program-driven Aspen HYSYS,an atmospheric and vacuum distillation and hydrocracking model have been established,which includes the complete process from petroleum to products,and can analyze and optimize refining process.This model contributes to the implementation of intelligent refining and the transformation of traditional refining enterprises towards intelligence and digitization.关键词
