Writen Solution please
You are working in a (very old) ethylene plant. (Liquid) process water is in contact with pure, vapour ethylene at 25C,24 Barg in vessel V-101. Two streams leave the vessel; vapour (mostly ethylene) and liquid (mostly water). The next step in processing the ethylene vapour is drying, where the water is completely removed. The liquid water stream leaving V-101 is sent to a pond where dissolved ethylene 'weathers off' completely. a) Sketch the process, including V-101, the dryer and the pond, and all streams leaving these process vessels. b) Assume equilibrium is achieved. What is the composition water in the vapour as it leaves the process (mol fraction). Assume the dryer is perfect. The vapour flow rate is 10kg/s ethylene, how much water is removed in the dryer, [kmol/h] ? c) What is the Henry's law constant for ethylene in water including units. (Hint: R. Perry, D. Green "Chemical Engineers' Handbook" available on-line from the University of Alberta Library is one good source) Reference your source. d) Assume equilibrium is achieved. What is the mol fraction of ethylene in the water leaving the process. e) If the water flow leaving V-101 is 30kg/s, what is the steady state release of ethylene to the atmosphere, [kg/day]Step by Step Solution
