METHOD AND INSTALLATION FOR THE HETEROGENEOUS SYNTHESIS OF METHANOL OR AMMONIA Russian patent published in 2007 - IPC C07C31/04 C07C29/152 C01C1/04 B01J8/04 

FIELD: chemical industry; methods and the devices for the heterogeneous synthesis of the chemical compounds.

SUBSTANCE: the invention is pertaining to the method of the heterogeneous synthesis of the chemical compounds such as methanol or ammonia and to the installation for the method realization. The method includes the catalytic conversion in the pseudo-isothermal conditions of the corresponding gaseous reactants routed through two sequentially located zones of the reaction. At that in the first zone of the reaction are gated through the immovable mass of the corresponding catalyst, in which the placed side by side mainly box-shaped lamellar heat-exchange components, through which the working fluid heat-carrier medium is gated. At that the gaseous reactants are fed into the first zone of the reaction after the indirect heat-exchange in the second zone of the reaction with the reaction mixture, which is fed into the second zone of reaction from the first zone of the reaction. The installation for the heterogeneous synthesis of synthesis of methanol or ammonia by the catalytic conversion of the gaseous reactants contains the sequentially connected the first and the second zones of the reaction, the corresponding heat exchangers mounted in the first and the second zones of the reaction. At that in the first zone of the reaction the heat exchanger is dipped in the mass of the catalyst and contains some disposed side-by-side box-shaped lamellar heat-exchange components, through which the working fluid heat-carrier is passing. At that the inlet into the first zone of the reaction communicates with the outlet of the heat exchanger in the second zone of the reaction. The invention allows to produce methanol or ammonia by the simple in realization method at the high conversion yield at the chemical installations of the high productivity at the low capital investments and the power input.

EFFECT: the invention ensures production of methanol or ammonia by the simple in realization method at the high conversion yield at the chemical installations of the high productivity at the low capital investments and the power input.
