Regarding the calculation method for the conversion rate of the methanol synthesis tower!
Thread Content
I’d like to ask the experts! Calculation method for the conversion rate of methanol synthesis towers! The gas flow rate entering the tower is 300,000 NM3/H, with a pressure of 6 MPA. The composition of the gas entering the tower is as follows: hydrogen: 24.14%, carbon dioxide: 0.72%, carbon monoxide: 11.38%, methane: 37.21%, and nitrogen: 26.55%. Composition of the off-gas: Hydrogen: 21.8%, Carbon dioxide: 0.71%, Carbon monoxide: 9.68%, Methane: 38.6%, Nitrogen: 29.21%. Give points for a reply!
Does the conversion rate refer to the conversion rate of CO or that of other substances?

Formulas for calculating the conversion rates of CO and CO2: Single-pass conversion rate of CO: 1－﹙y_methane_in*X_CO_out/y_methane_out*X_CO_in﹚ Single-pass conversion rate of CO2: 1－﹙y_methane_in*X_CO2_out/y_methane_out*X_CO2_in﹚ Total conversion rate of CO: 1－﹙y_methanefresh*x_CO_circulated/y_methane_circulated*x_CO_fresh﹚ Total conversion rate of CO2: 1－﹙y_methanefresh*x_CO2_circulated/y_methane_circulated*x_CO2_fresh﹚ Here, Y represents the inert gas components; it can be calculated using methane, nitrogen, or the sum of methane and nitrogen. In actual production, in order to reduce errors, we generally use the sum of these two values. These are formulas taught to us by professors from Nanjing University of Chemical Technology
