System and method for the integrated production of first and second generation ethanol and the use of integration points for said production

摘要

pThe present invention relates to a system and to a method for the production of ethanol and similar products from lignocellulosic biomasses (second-generation (2G) ethanol), especially bagasse and sugar cane stalks although not limited thereto -integrated into conventional methods for producing ethanol (first generation (1G) ethanol) such as for example using cane juice and/or molasses (a typically Brazilian method either in sugar and ethanol plants or stand alone distilleries) corn cereal wheat saccharine sorghum white beet comprising reutilization of flows and effluents. More specifically the present invention relates to an integrated method for production of ethanol and similar products with enhanced efficiency in terms of use of the raw material steam electrical energy and treated water in the main./p
