Ethane is chlorinate in a continuous reactor:

C2H6 + Cl2 C2H5Cl + HCl

Some of the product monochloroethane is further chlorinated in an undesired side reaction:

C2H5Cl + Cl2 C2H4Cl2 + HCl

a) Suppose your principal objective is to maximize the selectivity of monochloroethane production relative to dichloroethane. Would you design a reactor for a high or low conversion of ethane? Explain your answer. (Hint: If the reactor contents remained in the reactor long enough for most of the ethane in the feed to be consumed, what would be the main product) What additional processing steps would almost certainly be carried out to make the process economically sound?

b) Take a basis of 100 mol C2HsCl produced. Assume that the feed contains only ethane and chlorine and that all of the chlorine is consumed, and carry out a degree-of-freedom analysis based on atomic species balances.

c) The reactor is designed to yield a 15% conversion of ethane and a selectivity of 14 mol C2HsCI/mol C2H4CI, with a negligible amount of chlorine in the product gas. Calculate the feed ratio (mol Ch/ mol C2Ho) and the fractional yield of monochloroethane

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.

An external consultant recommends that a plant installs a bank of capacitors for power factor correction. this will reduce the peak electrical demand charges by an average of 93 kw every month. the plant current pays $13 per kw in peak demand charges. the capacitor bank will include 223 kw of fixed capacitors, and 183 of variable capacitors. the fixed capacitors cost $59 per kw, and the variable capacitors will cost $65 per kw. the consultant charges 21% of the equipment costs to install the capacitors. because this project will reduce the demand for the electric utility, they are prepared to provide a one-time rebate of $42 per kw of reduced demand. what is the simple payback period for this project (in years)?
