Question

A gas containing equal parts methane, ethane, and ammonia flows at a constant rate through a laboratory water-based absorption unit which absorbs 96% of the ammonia and retains it in the liquid. No ethane or methane is absorbed in the water and no water evaporates in the gas. Initially there were 5 kg of water and after 4 hours of operation, the liquid mass was 5.25 kg. Calculate the molar flow rate (mol/hr) of the gas stream coming in and the mol fraction of ammonia in the exit gas stream
