Abstract: 

IN THIS STUDY, AN INDUSTRIAL CARBON DIOXIDE HYDROGENATION UNIT IS SIMULATED. THE RESULTS ARE COMPARED WITH THREE-DAY EXPERIMENTAL DATA AND EFFECT OF REACTOR FEED TEMPERATURE AND REACTOR PRESSURE ON THE METHANOL FLOW RATE IS STUDIED. ACCORDING TO SIMULATION RESULTS THE UNIT IS NOT WORKING UNDER ITS OPTIMUM CONDITIONS. BY DECREASING TEMPERATURE AND INCREASING PRESSURE, THE PROCESS PRODUCTION OF METHANOL IS INCREASED. ALSO A NEW APPROACH IS PROPOSED TO MODIFY THE HYDROGENATION PROCESS AND REDUCE THE UNDESIRED BY-PRODUCT. IN THE NEWLY DESIRED SCHEME, THE OUTLET STREAM OF ORIGINAL CARBON DIOXIDE HYDROGENATION REACTOR IS SENT INTO A HEAT EXCHANGER AND AFTER COOLING, THE FLOW IS SENT INTO A NEW REACTOR. IN THE SIMULATION OF CONVENTIONAL AND MODIFIED PROCESS, THE CARBON DIOXIDE HYDROGENATION REACTOR INLET TEMPERATURE AND PRESSURE ARE REGULATED AS ADJUSTABLE PARAMETER FOR THE OPTIMIZATION OF THE PROCESS. IN NEWLY DESIRED SCHEME, AT THE SAME TEMPERATURE AND PRESSURE OF CURRENT UNIT, METHANOL PRODUCTION IN REACTOR OUTLET AND UNIT OUTLET IS INCREASED MORE THAN TWO TIMES.
