METHOD OF PRODUCTION OF THE OLIGOMER OF THE LINEAR ALFA OLEFIN AND THE INSTALLATION FOR THE METHOD REALIZATION WITH USAGE OF THE HEAT EXCHANGER Russian patent published in 2007 - IPC C07C2/08 C07C2/32 B01J8/18 C08F110/02 

FIELD: chemical industry; petrochemical industry; other industries; methods and the devices for production of the oligomer of the linear alpha olefin.

SUBSTANCE: the invention is pertaining to the method of manufacture of the oligomer of the linear alpha olefin. The invention presents the method of production of the oligomer of the linear alpha olefin in the reactor containing the liquid and the gaseous phases including the phases of the catalytic oligomerization of ethylene in the presence of the complex of iron with the derivative of 2,6-bis(arylimino))pyridine up to oligomer of the alpha olefin with the average molecular-weight from 50 up to 350 with the heat release, and withdrawal of the heat by means of the heat exchanger, which is not in the direct contact with the liquid phase, with usage of at least, a part of the gaseous phase in the capacity of the coolant. The invention also presents the installation for realization of the above indicated method of production of the oligomer of the linear alpha olefin. The technical result of the invention is the effective cooling of the reaction mixture, prevention of the clogging of the cooling devices by the settlings of the paraffin and polyethylene.

EFFECT: the invention ensures the effective cooling of the reaction mixture, prevention of the clogging of the cooling devices by the settlings of the paraffin and polyethylene.
