BRAZIL / BIOFUELS:
Brazil has made great progress in consolidating the technical production of biofuel from sugar cane. By 2012, the ethanol market is expected to be worth US$15 billion. Digital networks are used extensively and today over 50% of new sugar and ethanol plants use PROFIBUS. New projects include Tropical Bioenergia S.A., which has approximately 1000 PROFIBUS nodes connected to SMAR DFI302 DF73 controllers with SYSTEM302-7, a hybrid control system with decentralized architecture, which enabled this facility to quickly double production.In September 2007, Santa Elisa Distillery and SMAR signed a contract for the complete automation of 4 new plants This distillery is owned by the Santelisa-Vale Group, one of the major sugar-ethanol producers. The deal involves the supply of SYSTEM302-7 plus all instrumentation using PROFIBUS. It also includes the infrastructure of a Center of Integrated Operations (COI) similar to the successful Santa Elisa COI.
Included are more than 3200 SMAR PROFIBUS PA field instruments and 4 supervision and control systems that include 21 DF73 DPV1 CPUs per unit. AS-i technology is used for on-off valves and sensors. Two of the units – Ituiutaba and Itumbiara - are scheduled to start grinding in July 2008 and the other two - Campina Verde and Platina - in May 2009. Another facility – Usina Tropical, in Edéia, Goiás state – is part of the deal. It was contracted in June 2007, with project and conditions similar to the other four plants. All projects are integrated by Studio, a SYSTEM302-7 component that makes it possible to easily manage the software. One fourth of the primary energy used in Brazil comes from biomasses, a unique situation in the world. The position today, and the projected situation for 2012/13 are shown in the table.
