SYSTEM FOR METHANOL PRODUCTION FROM A SYNTHESIS GAS RICH IN HYDROGEN AND CO2/CO

摘要

A system for methanol synthesis from a synthesis gas rich in hydrogen and CO₂/CO that comprises a first adiabatic reactor (11) with a structure comprising an inlet stream (10), a first catalytic bed (12), one Venturi type mixing element (13), a first divergent nozzle (14), a second catalytic bed (27) and one outlet stream (28) all of them connected sequentially to each other; a first heat exchanger (15) connected to the outlet stream (28) downstream the reactor (11); a condenser (16) connected to the heat exchanger (15) downstream of the heat exchanger (15); a separator (18) connected to the condenser (16); a first cold gas stream (19) joining the separator (18) to both the first heat exchanger (15) and the first Venturi type mixing element (13); a first outlet stream (21) joining the heat exchanger (15) to a second adiabatic reactor (24) similar to the first adiabatic reactor (11).
