1. A gaseous stream whose composition is: 30% hydrogen, 27% nitrogen and
43% water is passed through an absorption column packed with granulated
calcium chloride, which exclusively absorbs 96.8% water. %. The column
packing was initially found dry, with a mass of 33.5kg; After a period of
continuous operation, the granules are weighed, observing a mass of 34.81kg.
Calculate the mass flow rate of water in the feed gas and the mole fraction
of water vapor in the exhaust gas.
