Document Summary
A fragrance is stripped out of flowers using 5 mol air. @ eqbm, what % of fragrance is in the oil? by using the y* eqn, we can relate y air to xoil yoil = 0. 2xoil: packed tower. Draw operating and eqbm lines and labelx the slopes. Chen3006_masstransferandseparations page 1 operating line slope = 0. 2 = 0. 2 l/g eqbm line slope = m = 0. 2. Chen3006_masstransferandseparations page 3 this is where the integral came from. Given t = 303 k, p = 1 atm. Follows raoult"s law gamma = 1 b/c ideal we"re just trying to relate y and x to make eqbm line. -> eqbm line now deriving it our kinetic eqn comes from mole balance over small area of the column. Chen3006_masstransferandseparations page 6 when we"re dilute, g is constant, but not when we"re concentrated we"re dilute for this problem divide by deltaz for ntu, need log mean delta t.
