HEXANE AS BY-PRODUCT OF ISOMERIZATION PLANT USING DIVIDING WALL COLUMN Russian patent published in 2023 - IPC C10G7/00 B01D3/14 C07C7/04 

FIELD: hexane production.

SUBSTANCE: invention is related to a dividing wall column system for production of hexane, the system comprising: a dividing wall column comprising a dividing wall that divides the dividing wall column at least partially into the first and the second sides, wherein one side consists of the first and the second sides configured to operate as a deisohexanization column, and the other side of the first and the second sides is configured to operate as a hexane column for producing hexane, said system further comprising a hexane tertiary treatment unit connected to the dividing wall column such that the hexane produced in a column with a dividing wall, is transferred to a hexane tertiary treatment unit, the hexane tertiary treatment unit comprising a hexane tertiary treatment reactor for hydrogenating at least a portion of the benzene contained in the resulting hexane. The invention is also related to a method for producing hexane and a method for producing a special boiling point mixture component using a dividing wall column system.

EFFECT: effective separation of components and reduced operating costs.
