PLANT FOR PRODUCING GASOLINES OR CONCENTRATES OF AROMATIC COMPOUNDS WITH VARIABLE NUMBER OF ACTIVE REACTION ZONES Russian patent published in 2024 - IPC C10G35/95 

FIELD: oil refining industry; petrochemical industry.

SUBSTANCE: plant for production of gasoline or concentrates of aromatic compounds with a variable number of active reaction zones, including three lines for supplying feedstock: the first line for supplying a low-aromatic hydrocarbon fraction, the second and the third for supplying a mixture of olefin-containing fraction and oxygenate, raw material tanks, and a reactor unit, implemented in the form of three separate reactors containing the first, the second and the third reaction zones, respectively, at least three heat exchangers arranged in series, a furnace, shut-off and control valves, in which the process line of the reaction flow from the reactor unit is connected to the bank of heat exchangers consisting of less than three consecutive heat exchangers. The heated raw material supply lines pass through the heat exchangers in such a way that the greatest temperature difference is provided for the third raw material supply line, the smallest for the second raw material supply line, each of the raw material supply lines is connected through shut-off and control equipment to the first, the second and the third reaction zones, and the reaction zones are connected to each other and to the reaction flow line in such a way that any of the reaction zones can be turned off without losing functionality of the installation.

EFFECT: simplification of the design.
