A fuel gas consists of 75% butane (C4H10), 10% propane (C3H8) and 15% butene (C4H8) by volume. It is to be fed to the combustion chamber in 10% excess air at 25ºC, where it is completely burnt to carbon dioxide and water. The flue gases produced are to be used to generate 5 bar steam from water at 90ºC. net calorific value (MJm-3) at 25oC Butane (C4H10) = 111.7MJm-3, Butene (C4H8) = 105.2 MJm-3. Propane (C3H8) = 85.8 MJm-3. air...

When air (21 mol% O2, 79 mol% N2) is placed in contact with 1000 cm3 of liquid water at body temperature, 37°C, and 1 atm absolute, approximately 14.1 standard cubic centimeters [cm3(STP)] of gas are absorbed in the water at equilibrium. Subsequent analysis of the liquid reveals that 33.4 mol% of the dissolved gas is oxygen and the balance is oxygen a) Estimate the Henry’s law coefficients (atm/mole fraction) of oxygen and nitrogen at 37°C b) An adult absorbs approximately...

Q.1 Iso-octane (a gasoline blend) can be produced by the reaction: C4H8 (Butene) + i-C4H10 (isobutane) > C&H18 (iso-octane) The reaction takes place in the liquid phase at 45 F and 90 psia. The desired production of isooctane is 918 mol/h. One feed stream containing 80 mol% butene, 12% n-butane and 8% propane is mixed-in equi-molar ratio- with another stream containing 73 mol% isobutane, 15% n- butane and 12% propane. The mixed feed streams enter the reactor at 45° F...
