It is desired to produce 200 million pounds per year of ethylene glycol. The reactor is to be operated isothermally. A 1lbmol/ft3 solution of ethylene oxide in water is fed to the reactor together with an equal volumetric solution of water containing 0.9 wt % of the catalyst H2SO4. If 80% conversion is to be achieved, determine the necessary reactor volume. Assumption: Ethylene glycol is the only reaction product formed. CSTRs in parallel. For two 800-gal CSTRs arranged in parallel with 7.67 ft3/min(v0/2) fed to each reactor, the conversion achieved The elementary gas-phase reaction (CH3)3COOC(CH3)3C2H6+2CH3COCH3 is carried out isothermally in a flow reactor with no pressure drop. The specific reaction rate at 50C is 104min1 (from pericosity data) and the activation energy is 85kJ/mol. Pure di-tert-butyl peroxide enters the reactor at 10atm and 127C and a molar flow rate of 2.5mol/min. Calculate the reactor volume to achieve 90% conversion in: (a) a CSTR (Ans.: 4700dm3 ) (b) a FFR (Ans.: 967dm3 ) It is desired to produce 200 million/pounds per year of ethylene glycol. The reactor is to be operated isothermally. A1lbmol/ft3 solution of ethylene oxide in water is fed to the reactor together with an equal volumetric solution of water containing 0.9wt% of the catalyst H2SO4. If 80% conversion is to be achieved, determine the necessary reactor volume. X=0.8 Assumption: Ethylene glycol is the only reaction product formed
