| Abstract: | The model of cocurrent multi-effect evaporation with extra vapor elicitation and condenser water flash is established. A computer-aided calculating method is presented. The algorithm is programmed by Visual Basic 5.0. A practical example shows that the calculating method is fast and accurate. With condensed water flash and preheating cane sugar solution from 26.7?℃ to 70?℃ by eliciting extra vapor， the fresh vapor expenditure of cocurrent four-effectevaporation is decreased by about 11%. |
