Steady operation of a petrochemical company and its installations as well as its efficiency depends in many respects on reliable and optimal performance of the technological equipment. It is common that technological equipment complexes often do not operate in optimal mode even if they are controlled by modern automatic control systems. If for some reason, the equipment comes to a halt, even the best technologies and control systems cannot compensate for the economic costs and losses caused due to downtime of the equipment. The solution to this problem is to construct computer models that allow one to encompass the technological equipment from a single standpoint and conduct necessary experiments without recourse to the existing equipment. The calculation and comparison of the results of computer modeling of the process of separation of hydrocarbon mixtures are based on real components and pseudocomponents using CHEMCAD software package. The computer model of the fractionating block was constructed by modeling a section of the technological scheme of liquid fuel production of the vacuum gas oil hydrocracking plant.

石化公司及其装置的稳定运行及其效率在许多方面取决于技术设备的可靠和最佳性能。技术设备综合体即使由现代自动控制系统控制，也常常不能以最佳模式运行，这是很常见的。如果由于某种原因设备停机，即使是最好的技术和控制系统也无法弥补因设备停机而造成的经济成本和损失。解决这个问题的方法是构建计算机模型，使人们能够从单一角度涵盖技术设备，并在不依赖现有设备的情况下进行必要的实验。烃类混合物分离过程的计算机建模结果的计算和比较是基于使用 CHEMCAD 软件包的真实组分和伪组分。通过对减压瓦斯油加氢裂化装置液体燃料生产工艺方案的一部分进行建模，构建了分馏块的计算机模型。
