Chapter 5, Problem 5.60P
Two humid gas streams are combined in a heated mixing chamber. The first stream contains 23.5 moIe ethane and 76.5 ethylene on a dry basis and enters the chamber at 25°C and 105 kPa at a rate of 125 L/min. The second stream is humid air, which enters at 75°C and 115 kPa at a rate of 355 L/mm. The product stream emerges at 65°C and 1.00 atm. A hygrometer is used to measure the water contents of the two feed streams and the combined product stream. The calibration curve for the hygrometer is a straight line on a semilog plot of y (mole fraction of water) versus R (hygrometer reading), which passes through the points
Hydrocarbon Feed Stream: R = 86.0
Air Feed Stream:
R = 12.8
(a) Derive an expression for y(R).
(b) Calculate the volumetric flow rate of the product stream and the molar composition of the product gas on a dry basis.
(c) Calculate the partial pressure of water in the product gas and the hygrometer reading for this stream.

A wet gas from a field in Iran is processed through two stages of separation; first
stage separator operates at 220 psia and 71°F, while the stock tank operates at atmospheric
pressure and 69°F. The separator gas condensate ratio is 41,000 scf/STB and the stock tank gas
condensate ratio is 450 scf/STB. The molecular weights of the separator gas and stock tank gas
are 25.0 and 35.0 lb/lb-mol, respectively. The stock tank condensate gravity is 0.85 and its

- Solid calcium (CaF2) reacts with sulfuric acid to form solid calcium sulfate and gaseous hydrogen fluoride. The HF is then dissolved in water to form hydrofluoric acid. A source of calcium fluoride is fluorite ore containing 96 wt% CaF2 and 4% SiO2.

Ninety-five percent of the ore dissolves in the acid. Some of the HF formed reacts with the dissolved silica in the reaction 6 HF + SIO2 (aq) – H2SİF6 (9) + 2 H2O (1) The hydrogen fluoride exiting from the reactor is subsequently dissolved in enough water to produce 60 wt% hydrofluoric acid.
