PLANT FOR PRODUCING GASOLINES OR AROMATIC COMPOUNDS CONCENTRATES Russian patent published in 2024 - IPC C10G35/95 

FIELD: oil refining industry; petrochemical industry.

SUBSTANCE: invention relates to a plant for production of gasoline or concentrates of aromatic compounds, including three supply lines for a mixture of feedstock - a low-aromatic hydrocarbon fraction, an olefin-containing fraction and oxygenate, raw material tanks, a reactor unit implemented in the form of a three-shelf reactor or in the form of three separate reactors, at least three heat exchangers installed in series, a furnace, shut-off and control valves. The outlet from the reactor unit is connected to the input of the line of sequential heat exchangers through the process pipeline of the main reaction stream to use the hot reaction product as a heating coolant, and the heated feed lines pass through the heat exchangers in such a way that the greatest temperature difference is provided for the third feed line, the smallest for the second feed line, the first, second and the third feed lines of the first, the second and the third feed streams are supplied to the first, the second and the third reaction zone, respectively.

EFFECT: simplification of the design of the plant.
