摘要:
采用精馏分离降苯技术,以不同含苯质量分数的模拟汽油为研究对象,根据Aspen Plus流程模拟软件中的Petlyuk模块建立隔板精馏模型,利用灵敏度分析对进出物料位置进行优化;此外,在不同回流比条件下,采用序贯二次规划算法对塔顶采出率和侧线采出率双变量进行优化,并与RedFrac常规精馏模型进行了对比分析。结果表明:采用隔板精馏塔,随着回流比的增加,汽油的收率和产值逐渐增加;当含苯质量分数为1%,3%,5%时,最高汽油收率依次为99.53%,96.35%,93.75%。隔板精馏工艺适用于含苯质量分数较低和较高的汽油,而常规精馏工艺更适用于含苯质量分数较低的汽油。
Abstract:
The distillation separation and benzene reduction technology was adopted, and the simulated gasoline with different mass fractions of benzene was adopted as the research object. According to the Petlyuk module in Aspen Plus simulation software, the partition distillation model was established, and the location of incoming and outgoing materials was optimized by sensitivity analysis. In addition, under the conditions of different reflux ratios, sequential quadratic programming algorithm was used to optimize the recovery rate at the top of the tower and sideline recovery rate, which was compared with the conventional distillation model of RedFrac. The results showed that with the increase of reflux ratio, the yield and output value of gasoline increased gradually with the use of the diaphragm distillation column. When the mass fraction of benzene was 1%, 3% and 5%, the highest gasoline yield was 99.53%, 96.35% and 93.75% respectively. The diaphragm distillation process was suitable for gasoline with low and high benzene mass fractions, while the conventional distillation process was more suitable for gasoline with low benzene mass fractions.
