Title:
加圧下に三相化学反応を実施するための方法および装置
Document Type and Number:
Japanese Patent JP4571275
Kind Code:
B2
Abstract:
The installation comprises a triphase reactor coupled with an external high pressure separator and system of valves to control the pressure in the reactor. The process for effecting a triphase chemical reaction under pressure, involving a gaseous phase and two non-gaseous phases, comprises the following stages : (1) circulation, co-currently and in a closed loop, of two non-gaseous phases in a reactor by injection of the gaseous phase in the lower part of the central region of the reactor to create an ascending circulation. The reactor comprises a central section and an annular space for return of the reaction mixture, the two sections being separated by a cylindrical partition; (2) separation and recovery in the upper part of the reactor of excess gaseous phase and a liquid fraction; (3) conveyance of the excess gaseous phase and liquid fraction to a high pressure separator external to the reactor; and (4) regulation of the pressure in the reactor and level in the separator by control of the flow rates of gas and liquid leaving the separator.
