This article describes the design and implementation of a unit for separating heavy vacuum gas oil, providing technical solutions and the results of its operation. Experimental studies were conducted using a laboratory model of the distillation column, and a mathematical model of multicomponent distillation was utilized for calculations. The main and auxiliary equipment for the vacuum distillation unit was also selected.
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.
