REACTOR FOR CONDUCTING EXOTHERMIC EQUILIBRIUM REACTIONS Russian patent published in 2021 - IPC B01J8/04 B01J8/06 C07C29/152 C07C31/04 

FIELD: engineering.

SUBSTANCE: proposed is a reactor for conducting exothermic equilibrium reactions, wherein a gaseous feed mixture is at least partially converted by means of a solid catalyst into a finished mixture containing at least one liquid reaction product condensed at a pressure in the reactor and temperatures below the temperature in the reactor, containing at least two reaction chambers connected consequently, fluidly communicating with each other and located in a common reactor shell, wherein each reaction chamber comprises the following consequently connected units in fluid communication with each other: (a) a preheating area suitable for heating a feed mixture or a gaseous product stream from an upstream reaction chamber, wherein use of the preheating area is optional in the first reaction chamber in the direction of the gaseous feed mixture stream, (b) at least one reaction area containing a catalyst, active with respect to the conducted exothermic equilibrium reaction, and a cooling apparatus in heat exchange communication with the catalyst, (c) at least one cooling area containing a cooling apparatus suitable for cooling a partially converted gaseous product stream filled with a condensable reaction product and outflowing from the reaction area to a temperature below the dew point of the gas, (d) a precipitation area containing a gas-liquid phase separation apparatus intended to separate the product stream outflowing from the cooling area into a stream of gaseous product freed from condensate and a condensate stream containing a liquid reaction product, (e) a pipeline tool for discharge of the condensate stream containing a liquid reaction product from the reactor and optionally a tool for supplying a condensate stream to an apparatus for processing a reaction product, (f) a tool for diverting the gaseous product stream freed from the condensate, and a tool for supplying the gaseous product stream to a downstream reaction chamber and/or a tool for diverting the gaseous product stream from the reactor. Also proposed is an application of the described reactor for producing methanol by converting feed synthesis gas containing carbon dioxide.

EFFECT: technical result is determination of a reactor providing, namely, a high degree of conversion based on the target products of an exothermic reaction per pass in the reactor and a possibility of reconfiguring and therefore optimising reaction conditions along the longitudinal coordinate of the reactor, thereby decreasing the recirculation coefficient to lower values.
