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.

A heavy vacuum gas oil separation unit was developed and implemented at an industrial enterprise with a stabilized composition. The technical solutions, the selected equipment and the results of the installation operation are described. On a laboratory model of a distillation column, experiments were made to develop technological conditions. In calculations of an industrial column with a new regular packing applied previously developed mathematical model of multicomponent distillaton. The mixture is represented as pseudo-binary in terms of fractions. In addition, software packages for plate-by-plate calculation of the column. The selection of the main and auxiliary equipment of the industrial vacuum distillation plant was carried out.

The pervaporation dehydration of diethylene glycol using ceramic tubular membranes with a hydrophilic selective layer formed from HybSi material was experimentally studied. The experiments were carried out over the process temperature range of 70–90°C at pressures in the permeate part of membrane unit in the range of 5–30 mm Hg and at diethylene glycol concentrations in the range of 93.5–99.8 wt %. Dependences of the membrane surface area required for the dehydration of diethylene glycol over a predetermined range of concentrations on productivity, process temperature, and vacuum were determined.

Экспериментально исследовано первапорационное обезвоживание диэтиленгликоля с использованием керамических трубчатых мембран с гидрофильным селективным слоем из материала HybSi. Эксперименты выполнены в диапазоне температур процесса 70–90°C, давлений в пермеатной части мембранной установки от 5 до 30 мм рт. ст. и концентраций диэтиленгликоля 93.5–99.8 мас. %. Определены зависимости площади мембранной поверхности, необходимой для обезвоживания диэтиленгликоля в заданном диапазоне концентраций, от производительности, температуры процесса и вакуума.

Results of researches on fire neutralisation of a firm waste (bio-logical and a waste of treatment-and-prophylactic establishments) on the trial installation work-ing by a principle of pulsing burning are resulted. In top internal space of a pulsation were gen-erated by the knot working on the liquid hydrocarbonic combustible: low-grade commodity fuel and a liquid combustible waste (a waste of petroleum products, petrochemistry etc.). Results tes-tify that on offered installation the cost price of neutralisation of a firm waste much more low, than on existing installations. High ecological compatibility and efficiency of their neutralisation is thus provided.
