摘要:
利用Aspen HYSYS软件，建立柴油加氢改质装置的全流程模型，通过考察反应器入口温度、氢油体积比和分馏塔塔顶石脑油采出量等操作参数对反应氢耗量、石脑油产量和质量的影响，在满足精度要求的基础上对操作参数进行模拟与优化。结果表明：提高改质反应器入口温度和氢油体积比有利于增加石脑油产量，但催化剂床层温度过高会影响催化剂寿命；提高分馏塔塔顶石脑油的采出量可升高石脑油干点、精制柴油闪点以及塔顶温度；在氢油体积比由1 400降低至1 200，石脑油干点由170.0 ℃升高至173.5 ℃的优化操作条件下，可节省中压蒸汽消耗量2.92 t/h，增加石脑油产量1.1 t/h。
Abstract:
The whole process model of the diesel hydro-upgrading unit was established by Aspen HYSYS software. The effects of operation parameters such as reactor inlet temperature， hydrogen to oil volume ratio and naphtha production at the top of the fracking tower on the hydrogen consumption， naphtha production and quality were investigated. The operation parameters were simulated and optimized on the basis of meeting the accuracy requirements. The results showed that increasing the inlet temperature and hydrogen to oil volume ratio of the modified reactor was beneficial to increasing the naphtha yield， but the catalyst bed temperature was too high to affect the catalyst life. The dry point of naphtha， the flash point of refined diesel oil and the temperature at the top of the tower could be increased by increasing the naphtha output. Under the optimal operating conditions of reducing the hydrogen to oil volume ratio from 1 400 to 1 200 and increasing the naphtha dry point from 170.0 ℃ to 173.5 ℃， the medium pressure steam consumption could be saved by 2.92 t/h and the naphtha production could be increased by 1.1 t/h.
