A continuous reaction requires a steady flow rate of ethylene. Ethylene is supplied by a 60.9 L gas cylinder initially at 2200.0 psig and 25.0C. Once leaving the cylinder, a regulator reduces the pressure to 15.0 psig and a valve allows 1.300 mL/s of ethylene at 25C to flow into the reactor. At this flow rate, how long would it take before the gas cylinder needs to be replaced (before the cylinder pressure reaches 15.0 psig)? Assume that the cylinder doesn't change temperature. Use the law of corresponding states and compressibility charts to describe ethylene within the cylinder. Atmospheric pressure is 1 atm. First, label the process flow diagram. What is the reduced pressure of ethylene at 2200.0 psig? What is z, the compressibility factor, for ethylene at 2200.0 psig and 25.0∘C? What is n intial the number of moles of ethylene in a full gas cylinder?

Question
A continuous reaction requires a steady flow rate of ethylene. Ethylene is supplied by a 60.9 L gas cylinder initially at 2200.0 psig and 25.0C. Once leaving the cylinder, a regulator reduces the pressure to 15.0 psig and a valve allows 1.300 mL/s of ethylene at 25C to flow into the reactor.
At this flow rate, how long would it take before the gas cylinder needs to be replaced (before the cylinder pressure reaches 15.0 psig)? Assume that the cylinder doesn't change temperature. Use the law of corresponding states and compressibility charts to describe ethylene within the cylinder. Atmospheric pressure is 1 atm. First, label the process flow diagram.
