Commercial plant to produce ethanol from bagasse using Iogen's process

There is a large opportunity to produce ethanol from sugar cane bagasse in Brazil. Raizen is building a plant in Piracicaba, Brazil to carry this out. The process includes: pretreatment with dilute sulfuric acid; enzymatic hydrolysis of the cellulose; fermentation of the sugars to ethanol by Saccharomyces yeast; and, distillation of the broth to recover cellulosic  ethanol. The plant is a scale-up of Iogen’s Demonstration plant in Ottawa and is scheduled to be operational by the end of 2014. 

 This presentation will describe how the design of the commercial plant builds upon the experience of operating the Demonstration plant and the synergies created by integrating with an existing sugarcane mill.
