27 FLASH SEPARATOR Description:
Find the flowrate of the liquid and vapor outlet streams of the flash separator Operate a flash separator in HYSYS to model the flash separation process A flash separator is performed to determine the product conditions and phases

28 FLASH SEPARATOR Liquid at a pressure equal to or greater than its bubblepoint pressure “flashes” or partially evaporates when the pressure is reduced, producing a two-phase system of vapor and liquid in equilibrium. Consider a simple process in which a multicomponent feed is allowed to separate into a vapor and a liquid phase with the phases coming to equilibrium, as shown in Figure below

29 FLASH SEPARATOR An overall material balance and component material balances can be written as: F = V + L Fzi = Vyi + Lxi where F = feed flowrate (kmol·s−1) V = vapor flowrate from the separator (kmol·s−1) L = liquid flowrate from the separator (kmol·s−1) zi = mole fraction of Component i in the feed (–) yi = mole fraction of Component i in vapor (–) xi = mole fraction of Component i in liquid (–)

30 FLASH SEPARATOR Consider a system containing one mole The material-balance equations are: L + V = 1 Dengan , , subtituting since

31 Flash Calculation of a ethanol-water mixture
Mulai dengan new case Pilih components ethanol and water Pilih FLUID PACKAGE yang sesuai (UNIQUAC) dan check parameter dari UNIQUAC apakah tersedia, kalau tidak tersedia apa implikasinya apa dan hal apa yang harus dilakukan? Enter Simulation environment manager dan buat stream dan namai stream tersebut Buat perhitungan flash untuk mendapatkan distribusi uap dan cairan jika kondisi feed adalah F= 100 kgmole/h, P= 150 kPa danT=92 deg C. Dengan menekan F12 dan memilih vessel terus separator dan beri nama stream keluar Vapor dan Liquid, untuk inlet pasang Feed.
