Document Summary
12-9 six pound moles of ethane, three lb-moles of propane and one lb-mole of n- butane are mixed in a closed container and the temperature is adjusted to 75of. Calculate the compositions of the gas and liquid at equilibrium at 75of and 300 psia. You may assume that the mixture behaves like an ideal solution. C3 n-c4 pd = 1/0. 00606 = 165 psia. This is a trial-and-error solution; only the calculation with the final trial value of ng = 0. 532 will be shown. Since xj = 1. 000, the trial value of nf = 0. 532 is correct, and the compositions of the liquid and gas are given in the table. 12-10 determine the compositions of the gas and liquid phases of the mixture in. 35 xj xj xj xj ng = 0. 5 ng = 0. 3 ng = 0. 15 ng = 0. 05. Since the xj is always greater than 1. 0, the mixture is a liquid at 5000 psia.
