The energy efficiency monitoring of the FCC exhaust-boiler is based on the parameters of temperatures, pressures and flow-rates taken from DCS. The energy efficiency of the exhaust-boiler can be calculated by the positive and negative equilibrium method through corresponding mathematical models. By way of computer programming, useful DCS data are read and the exhaust-boiler efficiencies are displayed on the DCS screen. The continuous dynamic monitoring of the FCC exhaust - boiler efficiency is thus realized. This energy efficiency monitoring system can reveal the boiler＇s operating status, by way of the exact determination of diagnosed and optimized. Through the saving economic performance is achieved. energy efficiency, the operational parameters can be of energy and upgrading of productivity, improved
