The gas-phase dehydrogenation of ethane to ethylene and hydrogen: сно сна + н, is carried out in a flow reactor with no pressure drop. the reaction is irreversible and it reaction rate is first order with respect to ethane concentration and, i. e. takca where rate of reaction of ethane (a), in moll-1s-1 specific rate constant, in s1 concentration of ethane (a), in moll-1 k = ca = the reactor is fed continuously with a mixture of gaseous components ethane and steam (an inert gas). the mixture is composed of 40 mol% ethane and 60 mol% steam. the gas mixture enters the reactor at 2 bar pressure with a total molar flow rate, fo, of 150.0 mols at a temperature of 700 °c. at this temperature the rate constant, k, for the reaction is 0.131 s1. calculate: i) the entering concentration of ethane, cao (in moll-1) ii) the entering volumetric flow rate of gas, vo (in ls1) iii) the expansion factor, e iv) the conversion of ethane if the reactor is a cstr of 50 m3 volume. v) the mole fraction of ethane, ethene, hydrogen and steam in the outlet stream from the reactor. a) if the outlet stream from the cstr (from part (iv)) is fed into another cstr, what volume (in l) of this reactor would be necessary for an overall conversion of 80% for ethane? b) if the outlet stream from the cstr (from part (iv)) is fed into a pfr, what volume (in l) of this reactor would be necessary for an overall conversion of 80% for ethane? assume the gases are ideal and the reactor is maintained at the same temperature and pressure as the inlet conditions. data: ideal gas constant, r = 8.314 kpalmol-1k-1 = 8.314 jmol-1k-1
