![]() From y-x plot for Methanol x = 0.65, 2.A10. At what pressure does pure propane boil at a temperature of -30oC? 160 kPaĪ. Within a homologous series such as light hydrocarbons as the molecular weight increases, the K value (at constant pressure and temperature) a. As the pressure increases, the K value a. At 100oC and a pressure of 200 kPa what is the K value of n-hexane? 0.29 b. Decrease the drum diameter and decrease the relative volatilities. ![]() ![]() In a flash drum separating a multicomponent mixture, raising the pressure will: i. The liquid is superheated when the pressure drops, and the energy comes from the amount of superheat.Ģ.A6. Feed location cannot be found from TF and z on the graph because equilibrium data is at a lower pressure on the graph used for this calculation. In the flash mixture enthalpy is unchanged but temperature changes. When pressure is dropped the mixture is above its bubble point and is a two-phase mixture (It “flashes”). At this pressure its enthalpy can be calculatedĪs a liquid. 2.A1.įeed to flash drum is a liquid at high pressure. New Problems and new solutions are listed as new immediately after the solution number. SPE 4th Edition Solution Manual Chapter 2.
