Factory concepts for very low steam demand and status of implementation

The export of power from cane sugar factories makes possible the production of “green energy” and proves nowadays to be a substantial source of revenue as well. Looking to the co-generation potential of the cane sugar industry, the power export is in fact still at a very early stage. This report gives an overview of concepts and measures that are required to achieve a low steam demand and high electrical power export for different factory concepts. The impact of sugar extraction by mills and diffusers as well as the option of producing refined sugar in an attached refinery is investigated. The factory models investigated allow steam demands to reduce to the range of 26–34% steam on cane. Such factory concepts are not theoretical any more but have been implemented and successfully proven in several plants in India, Brazil and Pakistan in the last five years. The report gives an overview of the actual achievements.
