In gas adsorption a vapor is transferred from a gas mixture to the surface of a solid. (See Section 6.7) An approximate but useful way of analyzing adsorption is to treat it simply as condensation of vapor on a solid surface. Suppose a nitrogen stream at 35°C and I atm containing carbon tetra chloride with a 15% relative Saturation is red at a rate of 10.0 mol/min to a 6-kg bed of activated carbon. The temperature and pressure of the gas do not change appreciably from the inlet to the outlet of the bed, and there is no CCl4 in the gas leaving the adsorber. The carbon can adsorb 40% of its own mass of carbon tetra chloride before becoming saturated. Neglecting the effect of temperature on the heat of vaporization of CCl4, estimate the rate at which heat must be removed from the adsorber (kJ/min) to keep the process isothermal and the time (mm) it will take to saturate the bed.
