To synthesise ethyl chloride, C2H5Cl, two feed streams, one with pure HCl(g) and the other with a mixture of C2H4(g) and C2H6(g), at 0C entered the reactor. The reaction is carried out in the presence of an aluminum chloride catalyst at 50C : C2H4(g)+HCl(g)catalystC2H5Cl(g)Hr(0C)=64.5kJ/mol The stream leaving the reactor passes through a condenser where it is cooled to 0C, condensing all of the ethyl chloride as product. The uncondensed gas stream leaves the heat exchanger at 0C. The molar flow rates based on mass balances are given in the flow diagram below. At the process conditions, the influence of pressure on enthalpy may be neglected. Data: Hv(C2H5Cl, independent of T)=24.7kJ/mol Cp.Catiscl(g)=0.052+8.7105TCp,C2Hl(9)=40.75103+11.47105T6.891106T2+17.661012T3Cp,CaHo(G)=49.37103+13.92105T5.816108T2+7.2801012T3Cp.HCl(g)=29.131030.1341105T+0.9715108T24.3351012T3 where heat capacity values are in kJ/molC and T is in C (a) As the reaction is exothermic, write an energy balance around the reactor and use it to determine the rate at which heat must be removed to keep the reactor temperature at 50C. [12 marks] (b) To remove the heat generated from the reaction, a portion of the liquid product is recycled to the reactor so that as the reaction proceeds, the heat released goes to vaporise the liquid. Determine the recycle rate of liquid ethyl chloride so that the reactor temperature will maintain at 50C. [5 marks] (c) A number of simplifying assumptions were made in the process description and analysis, so the results obtained using a more realistic simulation would differ from those you should have obtained in parts (a) and (b). List three of these assumptions. [3 marks]
