Methanol is synthesis from CO2 and H2 by using catalytic reactor. CO2 + 3H2 → CH3OH + H2O In a parallel reaction occurs in the reactor and CO2 reacts with hydrogen to produce CO and water: CO2 + H2 → CO + H2O The fresh feed to the process contains 25% of CO2 and 75% of H2. The reactor effluent passes to a condenser that removes essentially all of the methanol and water formed as product and none of the reactants and carbon monoxide are in it. To avoid the CO accumulation in the system, 15 % of the condenser off-gas is purged and the rest is recycled. The overall conversion of the carbon dioxide is 97% and the system off gas the mole ratio of H2 to CO is 2.3. a.
