Sažetak
This paper presents a model that uses the crude true boiling point curve and other routinely made laboratory measurements on crude distillation unit (CDU) for product properties prediction. The input to model is different type of crude. The objective of optimization is cost of energy consumption per tons of crude. The detailed model is based on a real refinery, a first-principle, nonlinear. The CDU model is a non-stage-by-stage, steady-state model and corrected by real process values. The model calculates the yields and properties of the products based on the feed information and product specifications. The proposed model has the next benefits in compares with commercials simulation models: adapted to real plant conditions, open source, flexible and fast execution. The model is very useful in the next applications: compare actual plant performance to the design case and to the optimal case, identify operating changes needed to maximize profits, ensure the highest return on investment for additional capital expenditures on the unit, identify the fouling level and for planning optimal shutdowns and maintenances the unit. The optimal solution obtained shows that the energy consumption could be decreased 3.2% over the normal operating condition.
