SYSTEM FOR CARRYING OUT THE EXOTHERMIC REACTION Russian patent published in 2007 - IPC B01J19/24 B01J8/06 

FIELD: chemical industry; devices for carrying out the exothermic reactions.

SUBSTANCE: the invention is pertaining to the devices for carrying out the exothermic reactions of the molecular oxygen and ethylene for production of the ethylene oxide. The unit of the reactor with the refrigerator contains the tubular reactor (1) and the tubular heat-exchanger (7). The reactor (1) has the inlet chamber (5) and the outlet chamber (6), the catalyst filled tubes (2) placed inside the reactor (1) and supported by the inlet tube plate (3) and the outlet tube plate (4). The heat-exchanger (7) has the upper edge and the lower edge and contains the upper tube plate (9) and the lower tube plate (10) retaining the tubes (8). The upper edge of the heat-exchanger (7) is integratedly fixed along the periphery of the bore of the outlet chamber (6) of the reactor (1) forming the integrated structure with the reactor. The hole of the outlet chamber (6) of the reactor is used for the reaction gases passing from the reactor (1) into the heat-exchanger (7) and through the tubes (8) of the indicated heat-exchanger. The reaction gases are cooled by the indirect heat-exchange with the heat-exchanging liquid fed into the heat-exchanger (7). The invention ensures the quick cooling, reduced formation of aldehydes, limitation of the time of formation of the by-products, consumption of the less material and operational inputs.

EFFECT: the invention ensures the quick cooling, reduced formation of aldehydes, limitation of the time of formation of the by-products, consumption of the less material and operational inputs.
