A unit for separating heavy vacuum gas oil of a stabilized composition from a wide fraction of vacuum gas oil with a capacity of 65,000 tons per year is designed and implemented at an industrial enterprise. Technical solutions, as well as the results of operating the unit, are described. Experimental studies into technological modes are carried out using a laboratory model of the distillation column. A previously developed mathematical model of multicomponent distillation is used to calculate an industrial column with a new regular packing, where the mixture is represented as pseudo-binary in terms of fractions. In addition, software packages for plate-by-plate calculations of the column are applied. The main and auxiliary equipment for the developed vacuum distillation unit is selected.

某工业企业设计并实施了年产6.5万吨/年从宽馏分减压瓦斯油中分离稳定成分的重质减压瓦斯油的装置。描述了技术解决方案以及操作该单元的结果。使用蒸馏塔的实验室模型对技术模式进行实验研究。以前开发的多组分蒸馏数学模型用于计算具有新规则填料的工业塔，其中混合物以馏分表示为伪二元。此外，还应用了用于对柱进行逐板计算的软件包。选用研制的真空蒸馏装置的主辅设备。
