Example 8.4: Flash Separator
When the pressure of a compressed liquid is brought between the bubble point and the dew point, the liquid "flashes," that is, it partially evaporates, creating a vapor that is enriched in the more volatile components and aliquid that is enriched in the heavier components. This simple process provides partial separation of the components.A mixture of heptane/decane at 1.8 bar, 120 °C contains 80% by mol heptane. At what pressure should it be flashed to obtain a stream that is 90% rich in heptane? What are the composition of the liquid and the amounts of the two phases?
Write balanced equations for the combustion of each component of the fuel gas.
Design a decanter for this duty, for a feed rate of 3500 kg/h. Concentrate on the separation of the water and aniline. The densities of water-aniline solutions are given in Appendix F, Problem F.8, available in the online material at booksite.Else..
The mass transfer coefficients are HL=0.436 m and kGa=6.06x10-7kg mol/s m3Pa and are to be assumed constant in thetower for the given concentration range. Use equilibrium data from Appendix A.3. Bynumerical or graphical integration, determine NG. ..
In the storage of flammable liquids, if the composition of the vapor-air mixture above the liquid surface falls within the flammability limits, a floating roof tank would need to used or the tank blanketed with inert gas. Check if the vapor compos..
The unit is to operate 8000 h/year. Determine the height and diameter of the absorption tower at conditions of minimum annual cost.
The enthalpy change of reaction for the balanced equation (with lowest whole-number coefficients) is H 67.7 kJ. If 2.50 102 mL of N2(g) at 100.C and 3.50 atm and 4.50 102 mL of O2(g) at 100.C and 3.50 atm are mixed, what amount of heat is..
when sulfuric acid is a component of polluted air it chemically attacks statues memorials and monuments made from

Hydrogen chloride gas, produced by burning chlorine with hydrogen, is required at a supply pressure of 600 kN/m2, gauge. The pressure can be achieved by either operating the burner under pressure or by compressing the hydrogen chloride gas.
At Chernobyl in 1986, hydrogen was produced by the reaction of superheated steam with the graphite reactor core: C(s)+H2O(g) yields CO(g)+H2(g) It was not possible to prevent a chemical explosion at Chernobyl
