Assignment Help Chemistry
Reference no: EM131109267

An analysis of the waste solvent vapors from a plant showed that the gas contained 20 mol% CH4, 20 mol% CS2, 10 mol% SO2 and 50 mol% H2O. It has been proposed that the gas be combusted with excess air and then emitted to the air. Air pollution regulations limit the concentration of SO2 in the stack gases to below 2 mol% on a dry basis. Using a sutiable basis for it.

1) Calculate the minimum percent excess air assuming complete combustion, that must be used to meet this requirement.

2) What is the composition of the stack gases on a wet basis?
