OIL RESIDUAL DELAYED THERMAL CONVERSIOIN PLANT Russian patent published in 2017 - IPC C10G9/00 C10G7/00 C10G31/00 

FIELD: machine engineering.

SUBSTANCE: invention relates to the oil residual delayed thermal conversion plant, including the fractionation unit, equipped with the gas discharge lines, light products, flux oil and the heavy gas oil outlet line to which the circulating residue supply line adjoins and at which the cracking furnace and the separator, equipped with the residue feed line in the thermal conversion reactor, equipped with the supply line of the circulating and balance residue vapours. In this case, the fractionation unit is equipped with the heavy fraction input and the thermal conversion vapours supply lines, the marine fuel and naphtha input lines, the latter - to the heavy gas oil outlet line. In addition, the plant is equipped with two mixers and three separators, the first of which is located on the heavy gas oil outlet line, the balance residue supply line is adjacent to the flux oil output line to the first mixer, located on the vapour part supply line from the first to the second separator, which is equipped with the vapours supply line to the thermal conversion vapour supply line and the residue supply line to the third separator, connected by the vapour supply line to the second mixer, located on the vapour remained part supply line from the first separator to the thermal conversion vapour supply line, also equipped with the residue supply line to the absorber, equipped with the absorption vapour supply line into the vapour supply line from the third separator, on which the vacuum-generating device is located, as well as the bituminic raw materials output lines, the input of the raw fuel oil part and the supply of the heavy fraction into the fractionation unit, to which the supply line of the raw oil residual remain part heated in the recuperative heat exchanger ajoins, located on the bituminic raw material output line.

EFFECT: plant allows to obtain the marine fuel and bituminic raw materials without using the water vapour.
