Introduction of Cogeneration has encouraged Sugar Industry to reduce their process steam consumption by employing innovative equipments and technology. Evaporation technology plays role in this progress. Evaporators use 2 to 2.5 bar pressure steam in four to five effects. This paper suggests a novel process employing low pressure vapours from pan and evaporators in multiple effects plate falling film evaporator. Using this technology, we are able to use available enthalpy and temperature of vapours for evaporation before letting it go to condensing and cooling systems. By eliminating evaporation process above 100 degree C, this concept aims to increase Plant capacity utilization, lowering cost of evaporation, enhancing power generation potential. Low temperature evaporation has potential to reduce scaling, inversion, colour formation and heat losses.
