A flash chamber operating 80 degrees C and 500kPa is separating 1000 kg moles/hr of a feed that is 10 mole %ethane, 5 mole %propane, 15 % n-butane, 10 % n-pentane, 12 mole % isopentane, 8 mole %n-hexane, 30 mole %heptane and 10% nonane.
What are the product compositions and flow rates?

Teach me how to calculate the vapour fraction...erm... i need you to show me one by one using the Newton Raphson method.
Sorry...i don't have any kind of programming here :laugh:
