INSTALLATION AND METHOD FOR ISOMERISATION OF HYDROCARBON FLOW Russian patent published in 2015 - IPC C07C5/22 C07C9/12 C07C9/16 B01J38/48 B01J38/04 

FIELD: chemistry.

SUBSTANCE: invention refers to an installation for the isomerisation of a hydrocarbon flow rich in hydrocarbon C4 and/or at least one of hydrocarbons C5 and C6. The installation comprises: A) a container, which comprises a fluid containing a hydrogen-rich gas; B) a device for displacing the above fluid flow receiving the fluid containing the hydrogen-rich gas from the above container; C) at least one drier receiving the fluid containing the hydrogen-rich gas from the above device for displacing the fluid; the above at least one drier operates in the first mode to dry the fluid containing the hydrogen-rich gas and in the second mode in the regeneration environment performed by means of a regenerant; D) a reactor connected with at least one drier for receiving the fluid containing the hydrogen-rich gas; at least one drier is connected to the above container by at least supplying the fluid containing the hydrogen-rich gas, or the regenerant through a flow orifice at least for the flow regulation and/or decrease in the pressure of the regenerant supplied into the above container. The invention refers to a method.

EFFECT: using the present invention enables reducing the undesired effect following the regeneration of the gas drier preventing functional failures of downstream equipment.
