Consider the following reaction in which methanol is produced from carbon monoxide and hydrogen gas:
CO + H2 ->CH3OH
The fresh feedstock to the process consists of 32 mol% CO, 64% H2 and 4% N2 and is mixed with a recycle stream in a ratio of 1 mol of fresh feed to 5 mol of recycled gas before it enters the reactor which has a N2 content of 13 mol %. Product from the reactor passes through a separator which removes all the methanol as product, with all the CO, H2 and N2 returned through the recycle stream and mixed with the fresh feedstock. To avoid the buildup of N2, a purge line is open on the recycle line. Calculate the composition of the stream between the reactor and the separator as well as the single pass conversion and the overall conversion.
