Calculation method for the conversion rate of methanol synthesis towers
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%, nitrogen: 26.55%. Composition of the gas exiting the tower: hydrogen: 21.8%, carbon dioxide: 0.71%, carbon monoxide: 9.68%, methane: 38.6%, nitrogen: 29.21%. Give points for a reply!
The conversion rate of hydrogen is 9.69%. The conversion rate of carbon monoxide is 14.94%
Reply to 2# guojing9113: Hehe! Could you tell me how you did the calculation? Thank you!
There is no flow rate of the gas exiting the tower – how can it be calculated then?
The outlet flow rate of the synthesis tower is required to calculate the conversion rate of each individual component
The outlet flow rate of the synthesis tower is required to calculate the conversion rate of each individual component
The conversion rate for carbon monoxide is 20%, and the conversion rate for carbon dioxide is 7.3%
CO conversion rate% = (1 - CO_out * (CH4 + N2)_in / CO_in * (CH4 + N2)_out) * 100 CO2 conversion rate% = (1 - CO2_out * (CH4 + N2)_in / CO2_in * (CH4 + N2)_out) * 100
Generally, it refers to the one-pass conversion rate or total conversion rate of the first-stage reactor and the second-stage reactor
Why is it CO that is emitted (*CH4+N2)? Shouldn’t it be the flow rate of the exhaust gas?
