Crude oil containing 5.0 mole per cent of gasoline is stripped by running the crude down a columnup which live steam is passed so that 15 kmol of steam are used/100 kmol of oil stripped. Determinethe number of theoretical plates required to reduce the gasoline content to 0.05 mole per cent, assumingthat the crude oil is non-volatile. The vapor–liquid relation of the gasoline in the oil is given by ye = 44x,where ye is the mole fraction in the vapor and x the mole fraction in the liquid. The temperature ismaintained constant by internal heating so that steam does not condense in the tower.
