Methane reacts with chlorine to produce methyl chloride (CH_3 Cl) and hydrogen chloride. Once formed, the methyl chloride may undergo further chlorination to form methylene chloride (CH_2C1_2). CH_4 + Cl_2 rightarrow CH_3Cl + HCl CH_3Cl + Cl_2 rightarrow CH_2Cl_2 + HCl A methyl chloride production process consists of a reactor, condenser, a distillation column and an absorption column. A gas stream consisting of 80 mole % methane and the balance chlorine is fed to the reactor. In the reactor a single pass chlorine conversion of essentially 100% is attained, the mole ratio of methyl chloride to methylene chloride in the product is 5: 1. The product stream flows into a condenser. Two streams emerge from the condenser: the liquid condensate, which contains essentially all of the methyl chloride and methylene chloride from the reactor effluent, and a gas containing methane and hydrogen chloride. The condensate goes to a distillation column in which the two component species are separated. The gas leaving the condenser flows to the absorption column where it contacts with an aqueous solution. The solution absorbs essentially all the HCl and none of the methane in the feed. The liquid leaving the absorber is pumped elsewhere in the plant for further processing, and the methane is recycled to join the fresh feed to the reactor (a mixture of methane and chlorine). Taking as basis of calculation the 100 kmol per hour of feed to the reactor: Draw and label the flowchart for the process Calculate the molar flow rate and molar composition of the fresh feed Determine the rate at which HCl must be removed in the absorber Determine methyl chloride production rate Calculate the molar flow rate of recycle stream
