Repsol Cartagena Utilities Real Time Optimization -- A Success Story
MetadataShow full item record
"In 1998 Honeywell Hi-Spec Solutions successfully implemented a Utilities Optimization system at Repsol's Cartagena Spain Refinery Complex. The Utilities Optimization System is implemented using Honeywell's Hi-Spec Solutions ProfitMax R100 system for Real Time Optimization (RTO) which runs on an NT-based workstation. ProfitMax uses the NOVA modeling system from DOT Products Inc. for non-linear modeling and optimization. Data is supplied through Uniformance PHD, Honeywell Hi-Spec Solutions' real time database. The cogeneration system is controlled using Honeywell's IDC 3000 system. The Utility System at Repsol Cartagena refinery is a cogeneration system that supplies both electricity and steam to the site. The surplus electricity is exported to the National grid. The system consists of the following: • Gas Turbine and Heat Recovery Steam Generator • Four fired boilers • Four steam headers at various pressures • Three Back-Pressure/Condensing steam turbo-generators • Plant condensate system • Fuel gas collection and distribution system • Process steam producers and consumers • Numerous dual drivers (steam/electric) for various plant loads "
