ISOMERIZATION ZONE IN THE ALKYLATE COMPLEX Russian patent published in 2022 - IPC C07C5/27 C07C5/32 C07C2/56 

FIELD: hydrocarbons processing.

SUBSTANCE: invention relates to methods for hydrocarbons processing. Described is a method for dehydrogenation and alkylation of a hydrocarbon stream containing n-butane, comprising feeding a hydrocarbon stream containing n-butane to an isomerization zone to obtain an isomerization zone product stream containing 60 wt.% isobutane and 40 wt.% n-butane; feeding the isomerization zone product stream to the dehydrogenation zone to obtain a dehydrogenation zone product stream, containing mixed butenes, isobutane and n-butane, and the mixed butenes contain 60 wt.% isobutene and 40 wt.% n-butene; feeding a dehydrogenation zone product stream to an alkylation zone to produce an alkylation zone product stream; feeding an alkylation zone product stream to a separation zone to produce an isobutane stream, an n-butane stream, and an alkylation product stream; and feeding an n-butane stream to the isomerization zone.

EFFECT: expansion of methods for processing hydrocarbons.
