| Abstract | ||||
| There is regenerate interest in the sugar industry to get to high performance in color removal during clarification process of raw sugar melt. Many efforts have conducted to approach the most proper alternative decolorants. The present study is focusing on investigation of cationic color precipitants “CCP” as alternatives of “H2O2” in clarification of raw sugar melt in Egypt. The experiments have performed using a pilot plant at Quos sugar factory, Qena governorate, Egypt. In these experiments, a comparison between two types of “CCP” (S TYPE 20 and TACELENE 4015) have been evaluated from the standpoint of decolorization efficiency. The behavior of the most effective matter has studied via the effect of dosage, pH, retention time and feeding point on the decolorization efficiency. A comparison between S TYPE 20 and hydrogen peroxide H2O2 in decolorization of raw sugar melt has conducted. The results show that, (S TYPE 20) is more effective than (TACELENE 4015) with percentage of color removal of 33.11% and 20.70% respectively. In addition, the results revealed that the proper experimental conditions for application S TYPE-20 are 7.4-pH, 30-minutes retention time and 100-ppm dosage. Addition of S TYPE 20 after clarification is the most proper feeding point. The results of comparison between S TYPE 20 and H2O2 show that decolorization percent are 40.40% and 27.70% respectively. Depending on these results, we concluded that the cationic color precipitants can be used successfully as decolorizing agents to replace hydrogen peroxide. | ||||
