Evaluation of hydrogen peroxide at Huletts refinery: Preliminary results † [Full subscriber]

The high costs and the very high reactivity of this chemical are negative factors that have prevented its full-scale application in sugar factories. Work was done in the USA to reduce the quantity of H2O2 required by dosing as wash water in raw sugar centrifugals. Based on the promising results, trials were done in the Technology and Engineering Group of Tongaat Hulett laboratory on raw sugar and WSM sugar. Full-scale tests were carried out at the Huletts refinery (Hulref) centrifugals on…
