A flash separator is performed to determine the product conditions and phasesFLASH SEPARATORLiquid 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

FLASH SEPARATORAn overall material balance and component material balances can be written as:F = V + LFzi = Vyi + Lxiwhere F = feed flowrate (kmols1)V = vapor flowrate from the separator (kmols1)L = liquid flowrate from the separator (kmols1)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 ()FLASH SEPARATORConsider a system containing one moleThe material-balance equations are:L + V = 1

Flash Calculation of a ethanol-water mixture Mulai dengan new casePilih components ethanol and waterPilih 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 tersebutBuat 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.
