原油蒸馏塔的模拟计算

在深入研究石油馏分虚拟组分切割方法的基础上，按照原油常压蒸馏塔的工艺原理，提出了联合使用BP法和SR法，以功能模块组合的流程模拟法求解原油常压蒸馏塔的新途径。它具有收敛性好、计算精度高等特点，为进一步实现原油常压蒸馏塔的优化和炼油厂全流程的模拟与优化奠定了基础。

Analog Calculation for Crude Oil Distillation Tower

Based on further study on cutting process of oil fraction virtual compositions, in accordance with the process philosophy of crude oil atmospheric distillation tower, the new approach of figuring out crude oil atmospheric distillation tower based on the functional module composed flow analog by combination of BP process and SR process is raised. It has the advantage of good contracting, high calculation accuracy etc. and it laid the foundation for further realizing the optimization of crude oil atmospheric distillation tower and the analog and optimization of the whole process of the refinery.
