根据结构族组成数据建立了模拟石油组分平均官能团结构的整数规划模型。根据平均官能团结构 ,应用UNIFAC模型即可计算含石油组分体系的气液平衡。该方法无需从现场装置获得试验数据来校正模型参数 ,因而是一种普遍化的方法。可用于酮苯装置的设计计算 ,并可推广到糠醛精制等装置
According to the data of structural group composition, an integer programming model was established to simulate the average functional group structure of petroleum components. Based on the average functional group structure, the UNIFAC model can be used to calculate the gas-liquid equilibrium for petroleum-containing systems. This method is a generalized method without the need to obtain experimental data from field devices to correct model parameters. It can be used in the design and calculation of ketone-benzene plant and can be extended to furfural refining and other devices
