Propane, adsorbed in a nonvolatile oil, is stripped with steam in a tray tower at 138Cand 1barabsolute pressure. The entering steam is pure. The liquid
Propane, adsorbed in a nonvolatile oil, is stripped with steam in a tray tower at 138Cand 1barabsolute pressure. The entering steam is pure. The liquid contains 18.1molepercent propane and is passed into the column at a flow rate of 120kmol/h. The stripped liquid must not contain more than 1.96molepercent propane. The amount of water vapor to be used
a)Please draw the system schematically and label all streams showing the flow rates and compositions.
b)Calculate the required amount of water vapor in kg/h.
c)Determine the concentration of the gas phase leaving the column.
d)Calculate the percentage recovery of propane.
e)Determine the ideal number of trays required.
