Forward feed evaporator
WebSpecific heat of feed is constant for all temperatures and concentrations. Overall heat transfer coefficient remains constant throughout the operation of the evaporator. 5 Evaporator is operated at steady state. Vapours from each effect are solute free. Forward feed arrangement is employed. WebTranscribed Image Text: A forward-feed double-effect evaporator, having 10 m2 of heating surface in each effect, is used to kg concentrate 1 of caustic soda solution from 10 per cent by mass to 30%. During a particular run, kN when the feed is at 373 kelvin (K), the pressures in the two calandrias are 375 and 180- respectively, m2 while the condenser …

WebIn the evaporator, the seawater fed in is heated to its boiling temperature and is partly evaporated by boiling. Heating is performed by passing steam inside the tube bundle. The heating steam loses its latent heat and condenses before it flows out of the tube bundle. WebFeb 1, 2024 · A double-effect evaporator with reverse feed is used to concentrate 4536 kg/h of a 10 wt % sugar solution to 50%. The feed enters the second effect at 37.8°C. Saturated steam at 115.6°C enters the first effect and the vapor from this effect is used to heat the second effect. The absolute pressure in the second effect is 13.65 kPa abs.
