BITUMEN PLANT Russian patent published in 2017 - IPC C10G9/00 C10G7/06 C10C3/04 C10C3/06 

FIELD: construction.

SUBSTANCE: bitumen plant comprises the raw material feeding line, the heat exchanger and the separator equipped with the separation residue feeding line and connected by the separation vapour feeding to the fractionation unit are arranged on the feeding line, the fractionation unit is equipped with the output lines of fractionation gas and light fractions, and is connected by the heavy gas oil feeding line and the vapour feeding line to the thermal conversion unit; the thermal conversion unit is equipped with the thermal conversion residue output line; the plant is characterized in that the feeding line of thermal conversion residue and that of part of the thermal conversion vapour are adjacent to the initial raw material feeding line before the separator, the vacuum fractionation unit is installed on the separation residue feeding line, which is connected by the feeding line of paraffinic gas oil from vacuum distillation to the heat conversion unit, and is connected by the vacuum distillation residue feeding line to the oxidation unit, the oxidation unit is equipped with the lines of air supply, black diesel fuel and bitumen output, and the sulfur recovery unit equipped with the lines of the purified gas and sulfur output is adjacent to the fractionation gas output line.

EFFECT: obtaining bitumen from raw materials rich in paraffins.
