Question

Zeolite is used to remove moisture from methane. A vertical column is filled with 1000.0 kg of dry zeolite. The zeolite has the capacity to hold 0.100 kg water/kg dry zeolite. Once the zeolite becomes saturated with moisture, it must be regenerated by heating. The inlet moisture content of the methane is 7.00% (by mass) and the outlet moisture content is 0.05% (by mass). How much methane (kg) will be produced before the zeolite must be regenerated? (Hint: Calculate the ratio of the water to methane at the inlet and at the outlet.)

Explanation / Answer

Inlet Moisture content of Methane 7.00% Outlet moisture content of Methane 0.05% Moisture to be absorbed by Zeolite= 6.95% 1 kg Dry Zeolite can hold water of                           0.10 kg 1000 kg zeolite can hold water of                      100.00 kg Methane that will be produced=100/6.95%=                1,438.85 kg So 1439 kg methane will be produced before the zeolite must be regenerated
