Group 8 In the process of methanol production, a gas stream containing 4 0 mol % C O 2 , 6 0 mol % H

Group 8
In the process of methanol production, a gas stream containing 40mol%CO2,
60mol%H2 is fed to the reactor. The product from the reactor is condensed
where liquid methanol is separated using distillation column. Unreacted gases
are recycle in a ratio of 3:2mol of recycle to moles of fresh feed. Parts of the
recycled gases are purged from the process. 90% of the purified methanol can
be achieved from this process with the overall conversion of 85% from the fed
gas. Recycling the unreacted gases can improve the methanol conversion to
80%-100% although one pass of reactant gas has about 25% conversion.
How much methanol is produced and what is the amount of recycle and purge
gases from this process? The reaction equation is CO2+3H2CH3OH+H2O.help
