Considerable interest exists in the conversion of coal into liquid products for production of desirable chemicals. Two of the main gases produced from in situ (in ground) coal combustion are H2 and CO. These product gases can be combined to form methanol (H2+CO-> CH3OH).

fresh feed --> mix point( fresh feed and recycle) --> reactor --> separator --> (liquid are product, gas goes to recycle and purge stream)

Your system has the following specifications:

1. The fresh feed contains 55% mass H2, 44.3% mass CO and 0.7% mass CH4
2. The outputs from the condenser are a liquid stream (pure methanol) and a gas stream containing the un-reacted components, inert methane and uncondensed methanol (5% of the total methanol produced in the reactor)
3. The purge stream is used to maintain the CH4 concentration in the gas stream leaving the condenser at 4% mole.
4. The single pass conversion of CO is 25%

Assuming a production rate of methanol of 100 mol/h,

1. Draw and label the flow chart completely
2. Perform a degree of freedom analysis and show that all of the unknowns can be solved

Calculate the following:
3. Recycle ratio of the H2
4. Feed rate of CO
5. Purge gas composition and rate
