3. A 200 lbmol/hr stream that is 95 mole% methylformate and 5% methanol is to be recovered from top of a distillation column. The feed to the column is 20 mole% methylformate and 80 mol% methanol, and 98% of the methylformate entering the column is contained in the distillate stream leaving the top of the column. (30 points) • Draw and label a flow chart of the process and do the degree of freedom analysis • Calculate the mass and mole fractions of methanol in the bottom stream and determine the molar flow rates of methanol and methylformate in the bottom and feed streams. Molecular weight of methanol = 32.04 g/mol Molecular weight of methylformate = 60.05 g/mol

In the process of methanol production, a gas stream flowing at a molar flow rate of 100 mol / min containing 32 mol% CO, 64 mol% Hz. and 4 mol% of N2 is led to the reactor. The product from the reactor is condensed where liquid methanol is separated. Unreacted gases are recycled in a ratio of 5: 1 mol of recycle to moles of fresh feed. Parts of the recycled gases are purged. The reaction equation is CO +...

Methanol is produced by reacting carbon monoxide and hydrogen. A fresh feed stream containing CO and H2 joins a recycle stream and the combined stream is fed to a reactor. The reactor outlet stream flows at a rate of 350 mole/min and contains 10.6 wt% H2 , 64 wt% CO and 25.4 wt% CH3OH. This stream enters a cooler in which most of the methanol is condensed. The liquid methanol condensate is withdrawn as a product, and the gas stream...
