GranBio Investimentos SASecond-generation Ethanol Plant in Brazil Automated with Yokogawa’s CENTUM VP, Batch Package, and PRM SolutionsExecutive SummaryGranBio Investimentos SA is a Brazilian industrial biotech company that was born out of the vision of bringing about a green revolution through the con-struction of second-generation ethanol plants that will produce cheap, clean-burning biofuel from readily available biomass. Following its establishment in June 2011 by Gran Investimentos S.A., a holding company in which the Gradin family are the primary investors, the company built Bioflex 1, the first commercial second-generation ethanol plant in the Southern Hemisphere. Bioflex 1 started operation in early 2014 and is able to produce 82 million liters of biofuel per annum, making it one of the largest such facilities in the world. As the main automation contractor (MAC) for the Bioflex 1 project, Yokogawa South America was in-volved from the front end engineering design (FEED) stage, performing the basic design for a control system and field instrumentation solution that will reduce costs and improve production efficiency throughout the lifecycle of the plant. Yokogawa in-stalled the CENTUM VP integrated production control system; the csTUNER control loop tuning software; the CENTUM VP Batch package to control the plant’s pretreatment, enzymatic hydrolysis, fermentation, and distillation/separation units; field instruments including FOUNDATION™ Fieldbus-enabled ADMAG AXF magnet-ic flowmeters, DPharp EJA series pressure/differential pressure transmitters, and control valves; and the Plant Resource Manager (PRM) asset man-agement package. Yokogawa South America was responsible for product delivery, engineering, and operator training.The Challenges and the SolutionsImproving productivitySecond-generation ethanol and other chemical pro-ducts are produced from non-food agricultural ma-terials and industry waste. The cost of producing biofuel with this method compares favorably to fossil fuels such as oil and natural gas, and it produces fewer greenhouse gases. The GranBio plant produces ethanol from energy cane, bagasse, and straw, all of which are readily available in Alagoas State. The raw materials used in this production process must first be pretreated to make the cellulose in the plant cell walls easier to break down with enzymes (hydrolysis) and solubilize hemicellulose sugars. The cellulose in the plant cell walls is in a matrix with other polymers, primarily hemicellulose and lignin, and the pretreatment of biomass with heat removes Plant InformationLocation: Sao Miguel dos Campos, Alagoas, BrazilOrder date: October 2013Completion: February 2014Overview of second-generation ethanol process“All in one” high density HMI displayMain process graphic displayInstrument faceplate displayProcess variables in trend displayCCTV view41Success Story CollectionChemical (Fine & Specialty Chemical, Biofuel)& Pharmaceutical
