摘要
以中国石化扬子石油化工有限公司炼油厂0.48 Mt/a的2号气体分馏装置为研究对象,利用Aspen Plus流程模拟软件对气体分馏装置工艺流程建立稳态模型,得到的模拟结果与装置生产实际情况相符合。在此基础上运用灵敏度分析工具,在保证各产品满足质量要求的前提下,以降低能耗、最大化增产丙烯为目标对装置精馏塔塔顶压力、回流比等重要操作参数进行分析优化。优化结果证明,在提高精丙烯塔塔顶压力、丙烯产品质量满足要求的条件下,气体分馏装置的丙烯收率有了显著提高。优化方案实施后,装置丙烯产品收率增加0.08百分点,每年可增加的经济效益约为92.05万元,说明应用流程模拟优化增产丙烯效果显著。
Taking the No.2 gas fractionation unit with the capacity of 0.48 Mt/a of SINOPEC Yangzi Petrochemical Co.Ltd.as the research object,the Aspen Plus process simulation software was used to establish steady-state model of the gas fractionation unit.The simulation results were consistent with the actual production of the unit.Based on the above results,the sensitivity analysis tool was used to optimize the analysis of important operating parameters such as the top pressure and reflux ratio of the distillation column of the unit,with the goal of reducing energy consumption and maximizing propylene production,while ensuring the quality requirements of each product.The optimization results proved that under increasing the pressure at the top of the propylene rectification column and the propylene product quality,the propylene yield of the gas fractionation unit was improved.After optimization,the yield of propylene product increased by 0.08 percentage point,and the annual economic benefit was about 920500 Yuan.The application of process simulation to optimize the production of propylene has a significant effect.
