TARGETING AND DESIGN METHODOLOGY FOR REDUCTION OF FUEL, POWER AND CO2ON TOTAL SITES

Simultaneous optimisation of production processes and total site utili ty systems provides a novel methodology that can reduce energy demands and emissions on a total factory site whilst simultaneously avoiding loss of cogeneration efficiency. This paper reports on the results of studies of total sites where the application of the methodology has ac hieved savings in fuel of up to 20%, along with improvements in global CO? levels and other emissions levels of at least 50% when compared t o those achieved by application to individual operational processes. T he novel methodology took into account the specific features of semi-c ontinuous and batch operations and also the opportunities offered by t he multi-objective optimisation of the design strategy for he total si te. The environmental costs and potential for regulatory action were a lso incorporated. Software tools were developed to support the total s ite approach which was subsequently tested and its capabilities valida ted by successfully solving various case studies from different indust rial sectors.
