Problem 1 Common salt and CaCO; react according to the following flowchart to produce CaCl2. The conversion of CaCO; in the reactor is 76%, based on the input to the reactor. All the unreacted CaCO3 is recycled back to the reactor. Calculate a) The kg of CAC12 produced per 1000 kg of feed. b) The molar composition of the exit stream c) The kg of CaCO3 recycled per 1000 kg of feed Note: NazCO3 is not reacting. Write the stoichiometry cquation

Question
Problem 1 Common salt and CACO; react according to the following flowchart to produce CaCl2. The conversion of CaCO; in the reactor is 76%, based on the input to the reactor. All the unreacted CACO; is recycled back to the reactor. Calculate a) The kg of CaCl2 produced per 1000 kg of feed. b) The molar composition of the exit stream c) The kg of CaCO; recycled per 1000 kg of feed Note: • Na2CO3 is not reacting. • Write the stoichiometry equation • The percent composition of the feed is mass percent (convert from mass fraction to mole fraction) • Start with the overall process and write atomic species balance for Ca, C, and Na (you should now be able to solve for the three unknown flowrates in the overall process). Continue with writing an equation that describes the conversion of CaCO3 in the reactor. • No reaction occurs in the separator and the mixing point (meaning input-output) NaCl - Na,CO3 Reactor Separator -CaCl2 Feed CaCO3 90% NazCO3 10% 1000 kg hr CaCO,
