EVAPORATÖR
İleri besleme kullanılan zorlanmış üç etkili bir evaporatör, 38,1 °C’deki 13658 kg/h debiye sahip %15 NaOH çözeltisi beslenmekte ve evaporasyon işlemi sonunda çözelti %50’ye derişiklendirilmektedir. Isıtma için kullanılan su buharları doygun olarak bilinmektedir ve ilk evaporatöre beslenen buhar basıncı gösterge basıncı olup 56,6 kPa’dır. Üçüncü etki içerisindeki basınç 6,76 kPa’dır. Isı aktarım katsayıları sırasıyla U1=6246, U2=3407 ve U3=2271 W/m².K olarak verilmektedir. Üç etkinin de yüzey alanı eşittir. a) yüzey alanlarını ve b) su buharı tüketimini hesaplayınız.

Calculate the surface area and steam consumption
A forward feed triple effect evaporator is used to fed 13608 kg/hr of NaOH solution containing 10 wt% solute. The entering feed temperature is 37.8°C. It is to be concentrated to a 50% NaOH solution. The steam used to enter at 58.6 kPa gage. The absolute pressure in the vapor space the third effect is 6.76 kPa. The heat transfer coefficient are U;=6246, U.=3407, and Uz=2271 W/m²K. All effects must have the same area. Calculate the surface area and steam...

Evaporation of Sugar Solution in a Multiple-Effect Evaporator. A triple-effect evaporator with forward feed is evaporating a sugar solution with negligible boiling- point rise (less than 1.0 K, which will be neglected) and containing 5 wt% solids to 25% solids. Saturated steam at 205 kPa abs is being used. The pressure in the vapor space of the third effect is 13.65 kPa. The feed rate is 22 680 kg/h and the tempera- ture 299.9 K. The liquid heat capacity...
