Abstract: This paper describes the selection of multiple process points before the distillation stage in alcohol production from sugarcane molasses, use of gravity separation methods (diluted molasses standing settlement, fouling removal at the bottom of the fermentation tank, mechanical centrifugationl) and gravity separation methods with the addition of chemical additives to perform antifouling processing on materials in alcohol production from sugarcane molasses. Physical and chemical parameters such as apparent fouling, total calcium magnesium and total sulfate were measured on materials and fouling to assess fouling removal effectiveness and characteristics. Based on apparent fouling removal rate by various control methods at various process points, optimal process points and methods for fouling removal were analyzed and technical protocols for fouling control and removal in alcohol production from sugarcane molasses were proposed.

Key words: molasses, alcohol, fouling, apparent fouling, fouling removal
