Unformatted text preview: : 4.58. Methane reacts with chlorine to produce methyl chloride and hydrogen Chloride. Once formed, the methyl chloride may undergo further chlorination to form methylene chloride (CHEClg) chloro. form, and carbon tetrachloride. ? mole ratio of methyl chloride to methylene chloride in the product is 5:1, and negligible amounts of chloroform and carbon tetrachloride are formed. The product stream ﬂows to the condenser. Two streams emerge from the condenser: the liquid condensate, which contains essentially all of the i (3) Choose a quantity of the reactor feed as a basis of calculation, draw and label a ﬂowchart, and ‘ determine the degrees of freedom for the overall process and each single unit and stream mixing point. Then write in order the equations you would use to calculate the molar ﬂow rate and molar composition of the fresh feed, the rate at which HCI must he removed in the absorber, the methyl chloride production rate, and the molar flow rate of the recycle stream. Do no calculations.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
