Observations from Energy Audits in the Petrochemical Industry
MetadataShow full item record
Du Pont Energy Management Services has done energy studies at a number of refining and petrochemical plants. These studies are done through a rigorous, systematic, and objective analysis of all plant systems and equipment that convert, transport, use, or reject significant quantities of energy. The approach taken for these studies and several examples of specific energy savings items will be reviewed. The importance of an optimum steam system for overall energy efficiency will be discussed. The economical use of topping turbines in the steam system versus other mechanical energy options, savings possible from combustion versus other mechanical energy options, savings possible from combustion excess air control in boilers and fired heaters, and energy saving techniques on distillation columns will be reviewed. The discussion will also include an explanation of the key points in developing a successful energy conservation program.
