CHEMICAL ENERGY BALANCE - EXAMPLE 11.4 : Calculate the bubble temperature T at P = 85-kPa for a binary liquid with x(1) = 0.4. The liquid solution is ideal. The saturation pressures are Psat(1) = exp [ 14.3 - 2945 / (T + 224) ], Psat(2) = exp [ 14.2 - 2943 / (T + 209) ] where T is in degree Celsius. Please take note that x(1) + x(2) = 1. Please take note that y(1) + y(2) = 1, y(1) = [ x(1) * Psat(1) ] / P, y(2) = [ x(2) * Psat(2) ] / P, * is multiplication. P is in kPa.

CHEMICAL ENERGY BALANCE - ANSWER 11.4 : By trial and error, T = 84.37 degree Celsius. Excel program may be used, either by Solver or Goal Seek. Overall equation : y(1) + y(2) = 1 = { 0.4 exp [ 14.3 - 2945 / (T + 224) ] + 0.6 exp [ 14.2 - 2943 / (T + 209) ] } / 85. Solve the equation by computer iteration with one unknown will produce T = 84.37 degree Celsius. Let x(2) = 1 - x(1) = 1 - 0.4 = 0.6, P = 85.

(a) Calculate its flowrate in the unit of mega US-gallon per day or MGD. (b) The following formula is written next to the chlorine feed point : (chlorine feed rate, lb / day) = (flowrate, MGD) X (dose, mg / L) x (8.34). If this formula is correct, then what should the chlorine feed rate to be in pounds per day (lb / day) if the desired dose is 2 mg / L. (c) Prove by calculations that the constant 8.34 in the formula next to the chlorine feed point is correct. Let 1 US-gallon = 3.78541 L and 1 mg = 0.0000022046 pound.
