| 摘 要： | 用三次样条插值法处理实沸点蒸馏数据,所得二阶光滑曲线用于描述实沸点蒸馏曲线。结合实组分物性数据库,根据实沸点蒸馏曲线确定原油的组分和组成。对实组分体系运用常见状态方程描述过程热力学性质,并按照新的动态模型求解策略,实现了常减压蒸馏过程的实时动态模拟。

| Abstract: | A segment tri polynomial which is a continuous and smooth curve can be derived by processing the figures of true boiling points with tri sample trial and error. From the curve, a composition and its components can be figured out through existing physics database. Equation of State are used to compute equilibrium coefficients. This model accomplishes the simulation of crude distillation process in a relative complicated system by means of true component cutting methodology. |

| Keywords: | crude distillation process true component cutting dynamic model |
