OPTIMIZATION OF POWER GENERATION FROM BAGASSE AND SUGARCANE WASTE IN A BRAZILIAN SUGAR AND ALCOHOL MILL
Brazil is, along with the USA, one of the worlds largest alcohol producers. Since the 80s efforts have been made to reduce alcohol cost production from sugar cane, in a well established and worldwide famous program called Pro-Alcohol, a Brazilian answer to the oil crisis at that time. Nowadays the country is facing a new dilemma, a restriction in its capacity of producing electricity. Despite the huge hydro energy still available to be explored, most of such potential lies in northern regions of Brazil, where power demand is low and where big reservoirs must be formed in order to stabilize power production. This fact brings a significant opportunity for “exporting power production from the more than 300 sugar and alcohol mills spread out through the southeast region. This concept is based on exploring a better utilization for the bagasse which has so far been very inefficiently burnt in low pressure boilers, together with a sugarcane waste collection. Todays practice of burning such waste in the cropland, prior to harvesting, will soon be banned across Brazil. More than 90 new plants are now under development and by 2015 alcohol production should reach twice the current annual volume of 17 billion liters. This study shows how to improve power production based on an installed upgrade of a thermo power bagasse plant in the South of Brazil This improvement can almost double its final output electricity capacity. If properly adopted in other projects, the concepts described herein could easily add more than 5 GW to Brazilian power production capacity in the near future, at competitive costs and low installation and operation risks.
