2.3Mt/a催化裂化装置吸收稳定系统模拟及优化
Simulation and optimization of 2.3 Mt/a catalytic cracking absorption and stability system
摘要
Abstract
Systematic simulation study of the absorption stabilization system process of a 2.3 Mt/a catalytic cracking unit in a refinery was carried out using Aspen Plus,a chemical process simulation and analysis software.Firstly,the process model of absorption stabilization system was obtained by simulating the actual production data,which was consistent with the actual operation results of the device,thus ensuring the feasibility and correctness of the process simulation.After that,by analyzing the process conditions,a flash tank was used instead of a re-absorption tower to obtain suitable hydrocarbon components as a supplementary absorption liquid,which could enhance the absorption process of the absorption tower.This optimization scheme reduces the number of stream and tower equipment,and significantly reduces the investment of equipment cost.After optimization,the absorption and stabilization process reduce the energy consumption of the supplementary absorbent heat exchanger and desorption tower reboiler in the original process,resulting in a decrease of 16.38 GJ/h in comprehensive energy consumption compared with the original process,with an energy saving rate of 2.21％.This can increase the factory's benefits by approximately 2.183 74 × 107 yuan/a.关键词
