ptsDioxane has historically been used to stabilize chlorinated solvents and more recently has been found to contaminant numerous consumer and food products. Based on this experimental evidence, the US Environmental Protection Agency EPA has listed dioxane as a high priority chemical and classified it as a probable human carcinogen. You are tasked with analyzing a stage stripping column that operates isobarically at and isothermally at and is used to purify water contaminated with dioxane. The entering liquid stream contains moldioxane D and the balance water W If the amount of pure nitrogen N available is how much liquid feed in can this column treat if the EPA requires the column to produce a liquid stream containing moldioxane in water. Assume solute free flow rates are constant, meaning water is nonvolatile and nitrogen does not dissolve in water. Use the Wilson equation to describe the dioxane and water equilibrium. The Wilson constants for dioxane D and water W are given below and the Antione's Constants for dioxane are given below in terms of and
