For beginners: small issues with FLASH2
Thread Content
I’m a beginner with ASPEN and FLASH2 Blocks, and I have two questions: In the flash specifications settings, 1) Does \"Pressure\" refer to the feed pressure or the pressure used by the equipment? 2) Does Vapor fraction refer to the gas-liquid ratio of the condensate? Thank you so much!
1. Operating pressure of the equipment； 2. It refers to the mole ratio of the vapor phase to the liquid phase after flashing...
Reply to 2# EagleYuan: If the gas-liquid ratio is 1/3 after FLASHing, then is VAPOR FRACTION=0.33 or 0.25?
This post was last edited by EagleYuan on 2010-10-20 at 14:33. The highest value for the vapor fraction is 1, which indicates the mole ratio between the vapor phase and the feed material... So, for a gas-liquid ratio of 1/3, the vapor fraction is 0.25. . . .
Pressure refers to the operating pressure of the flasher, while the vapor fraction denotes the proportion of the gas phase in the total material within the flasher
