Abstract

The sugar industry is continually researching methods to improve and enhance the efficiency of the sugar manufacturing process, with a particular focus in the evaporation stage due to high thermal energy demands. The evaporation stage primarily utilises multi-effect Robert evaporators, which are a specific type of rising film evaporator that use steam to condense and transfer heat across vertical tubes to the sugarcane juice to boil and evaporate. By extensive investigation of this effect, a single-tube evaporator has been redesigned and revised from the previous research. This new, mobile, and adjustable single-tube apparatus has been developed and analysed. Preliminary test with steam form pure water found steady condensation rate in majority of the 1-hour operation period. In addition, test with steam with Nalco-2857 solution also achieved consistent condensate rate. Furthermore, the total liquid weight condensed from steam with 100ppm of Nalco-2857 was 25.7% higher than that from steam of pure water at the end of one hour. Further investigation will be conducted to test the impact of various chemical solutions (corrosion inhibitors) on the condensation heat transfer rate, and the optimal substance and the optimal concentration.
