采用Aspen Plus模拟软件建立了重整拔头油C5混合烷烃分离单元的模拟模型,并对热泵精馏技术与常规精馏技术进行了对比分析。结果表明:在满足正戊烷与环戊烷质量分数均不小于99.0%的分离要求下,相比常规精馏技术,热泵精馏技术可大幅降低脱正戊烷塔的回流比,由6.40降至0.86,系统冷量能耗、热量能耗以及总能耗依次节省10.1%,79.7%和45.0%。
- Abstract:
-
A simulation model of C5 mixed alkanes separation unit of reforming head oil was established by using Aspen Plus simulation software, and the heat pump distillation technology and conventional distillation technology were compared and analyzed. The results showed that under the separation requirement of mass fraction of both n-pentane and cyclopentane was not less than 99.0%, the heat pump distillation technology could greatly reduce the reflux ratio of the de-n-pentane column from 6.40 to 0.86 compared with the conventional distillation technology. The cooling energy consumption, heat energy consumption and total energy consumption of the system were saved by 10.1%, 79.7% and 45.0%, respectively.
