Figure 4.36 shows a system to cool reactor effluent and separate light gases from hydrocarbons. K-values at 500 psia and 100^οF are:

(a) Calculate composition and flow rate of vapor leaving the flash drum. 

(b) Does the liquid-quench flow rate influence the result? Prove your answer analytically.
