Question

QUESTION 2 10 points CH3OH. Methanol is produced by the reaction of CO with H2: C0+2H2 A process flowchart is shown below. Condenser 4 CH,OH 275 moles H, 0.227 Product сн он со. 0.330 - CH,OH: 0.443 1. What is the overall conversion of CO? 2. If the single pass conversion of H2 is 0.7952, calculate the amount of H2 fed to the reactor. 3. Calculate the amount of CO fed to the reactor (method of molecular species). 4. What is the extent of reaction?

Answer 1

This is a typical mass balance with reactions problem from process calculations. Proceed as follows:

co Ha CO 12 LHн сиң * 5k 1 Chon: 0.004 Freshdeed 21Reacties 137 275 mole H2; 0.227 CH₂OH. (0:0,330 Cot2H2 CH₃OH CH₃OH 10.443 I since the final product taken out is only pure CH3OM, we have no co left to be converted. Hence the overall conversion of co is 100% OR 1.00. 2. single pars conversion of H₂ = 0.7982. males in stream3: ni (species) = model of here M3 (H2) ► 0.227x275 = 62.425 mal.

For each 2 moles of Ma converted, one mole of co would also be converted & one mole of Cloon would be produced. . .
