基于Petro-SIM的常减压流程模拟和参数优化

Process simulation and parameter optimization of atmospheric & vacuum distillation unit based on Petro-SIM

利用流程模拟软件对常减压装置进行工艺流程模拟和操作参数优化对于指导生产具有重要意义。以金陵石化公司所加工的原油为基础,通过原油数据校正选择合适的原油数据,结合现场工艺数据,基于Petro-SIM进行初馏塔和常压塔的模拟计算。同时,通过对部分操作参数进行优化,在保证侧线产品质量的前提下,有效地改善了常二线和常三线的分离精度,提高了常二线轻柴油的收率和常压塔的整体收率。

Application of process simulation software to make process simulation and operating parameter optimization of the atmospheric&vacuum distillation unit has significant meaning for guiding production.With the crude oil processed by Jinling Petrochemical Company as the basis,by correcting crude oil data to select proper crude oil data and combining the process date from the site,simulation calculation was made to the primary tower and atmospheric tower based on Petro-SIM.In the same time,by optimizing part operating parameters,and under the premise of ensuring side draw product quality,the separation accuracy of the atmospheric cut2and atmospheric cut3was effectively improved,and the yield of the atmospheric cut2light diesel and overall yield of the atmospheric tower were improved.
