Synthesis of acetic acid via methanol hydrocarboxylation with CO Nat. Since it takes 2 L of H 2 to react with every 1 L of CO, the H 2 will be limiting since we don't have twice as much H 2 as we have CO. Now we can use the limiting reactant (H 2) to find the theoretical yield (volume) of CH 3 OH. Douglas, C. M. (2013). Ed.

In this section, the impacts of eight parameters on the methanol production cost were determined using sensitivity analysis. (2003). 0 A synthesis reaction takes place when carbon monoxide (CO) and hydrogen The reaction will form more reactants CO and H2. 11, Issue 3, Physical Chemistry Chemical Physics, Vol. In the optimal region of study, the inlet pressure and temperature to the first reactor show significant impacts on the methanol production cost. - The maintenance and repairs are 5% of fixed capital investment. The efficiencies of all compressors were assumed at 75% (adiabatic). doi: 10.1016/j.apcatb.2008.11.018. However, the methanol production cost via direct CO2 hydrogenation is 22.5 times higher than the cost of conventional process (Atsonics et al., 2015). CO If S < 0, it is exoentropic. The unreacted CO2 and H2 then entered the second equilibrium reactor to produce more methanol product. The synthesis of methanol from carbon monoxide and hydrogen gas is described by the following chemical equation: Mercury is a liquid metal having a density of 13.6 g/mL. The percent error of the model was estimated by comparing between the predicted methanol production cost with the actual production cost. 54, Issue 13-15, Catalysis Communications, Vol. Since there are an equal number of atoms of each element on both sides, the equation is balanced. The results showed that the methanol production rate can be increased by 7% with higher feed pressure and lower feed temperature (Hoseiny et al., 2016).
