A cellophane manufacturing plant uses various organic solvents in its process, among which we can find THF (tetrahydrofuran), a substance classified as mutagenic and carcinogenic. The plant evacuates from the industrial warehouse a volume of 1,200 m3 of air/min (@ 25 C and 1 atm pressure), the THF concentration measurements in the gas stream indicate values of 1,283.2 ppm THF. The gas stream is passed through an adsorption system that uses sepeolite. The tank has the following dimensions: 4 m in diameter and a bed height of 8 m. The maximum THF retention capacity in sepeolite is 212 mg THF/g sepeolite. Suppose: that at the outlet of the sepeolite column the THF concentration is 0.001 ppm. The density of sepolita is 0.95 Kg/Lt

Suppose: that at the outlet of the sepeolite column the THF concentration is 0.001 ppm. The density of sepolita is 0.95 Kg/Lt How many hours can the sepeolite column operate before becoming saturated with THF?
