a) A feed of 100 kg/h containing 2% solids is to be concentrated to yield a product containing

10% solids. Estimate the flow rate of thick liquor and water evaporated
b) A gas containing 20% CH4, 80% N2 is burnt with 10% excess air. Find the composition of

gases leaving the chamber, if 80% of methane burns to CO2 and rest leaves unburnt
