Methane Reacts with chlorine producing methyl chloride and hydrogen chloride (Reactive Atomic Balance)
Note: Please assume in your calculations that the Reactions producing negligible CHCL3 and CCl4 are irrelevant and can be taken out of the problem. Thank you!
Methane reacts with chlorine to produce methyl chloride and hydrogen chloride CH4 Cl, CH Cl HC1 Once formed, methyl chloride may undergo further chlorination reactions via CHI C1 C1, CH Cia HC1 CH Cl, C1 CHC1, HC1 CHC13 C1 CCl, HC In a methyl chloride production process, methane and chlorine are fed to a reactor in a mole ratio of 5:1. A single-pass convers on of 100% may be assumed The mole ratio of CH3Cl to 2 in the product is 4:1, and negligible amounts of CHCl3 and CCla re produced. The CH2C product gases are cooled, condensing CH3Cl and CH2C which are then separated in a distillation column. The gas leaving the condenser goes to a scrubber in which HCl is absorbed The gas leaving the scrubber, which may be considered pure methane, is recycled back to the reactor. For a production rate of 1000 kg CH3C /hr (a) Draw the process flow diagram (b) Calculate, using the atomic balance method (i) the flow rate and molar composition of the fresh feed (ii) the rate at which HCl must be removed in the scrubber, and (iii) the molar flow rate of the recycle stream
