The production of ethylene glycol from ethylene chlorohydrin and sodium bicarbonate CHOHCH2Cl + NaOHCO3 (CHOH)2 + NaCl + CO is carried out in a semi-batch reactor. A 2-molar solution of ethylene chlorohydrin is fed at a rate of 3.5 mol/minute to 1250 dm of a 1-molar solution of sodium bicarbonate. The reaction is elementary and carried out isothermally at 50C where the specific reaction rate is 3.2 dm/mol.h. Higher temperatures produce unwanted side reactions. The reactor can hold a maximum of 3000 dmof liquid. Assume constant density (p=1000g/L). (a) Consider that CO2 remains in the reactor as being dissolved in the solution (no flow out of the reactor). Plot the conversion, concentration of reactants and products, and number of moles of glycol formed as a function of time until the reactor is full. (b) Consider now that CO2 leaves the reactor when it is formed (as show in the equation above). Plot the conversion, concentration of reactants and products, and number of moles of glycol formed as a function of time until the reactor is full. (c) Suppose this reaction was carried out in a batch reactor instead. The sealed reactor would be filled to its maximum capacity, with an initial concentration of each reactant of 2M. Plot the conversion, concentration of reactants and products, and number of moles of glycol formed as a function of time until a conversion of 90% is reached.
