Since its initial development in the 1980′s, Real-Time Optimization (RTO) has been widely appreciated as an efficient way to optimize process decision variables and improve economic performance of refineries. RTOs consist of nonlinear optimization

There is not a consensus about the benefits of implementing Real-Time Optimization (RTO) technologies to increase the profit of process plants. A lack of experimental and theoretical works which evaluate the scope and limitations of different RTO app

This paper addresses the optimization of cleaning schedules of heat exchangers in crude preheat trains in petroleum refineries. The optimization approach is based on a heuristic scheme composed of a set of movements according to a greedy rationale. E

The fuel consumption in the fired heaters of atmospheric distillation columns for petroleum refining increases during the refinery operation. This effect is a consequence of fouling in the heat exchangers of the crude preheat train. The application o

Crude preheat trains are heat exchanger networks which heat the crude oil stream in the petroleum distillation using hot product streams and pumparounds. The final heating step is executed in a furnace. The thermal efficiency of this process is stron

Several fouling mitigation techniques depend on the capacity of predicting fouling rates. Therefore, the identification of accurate fouling rate models is an important task. Crude fouling rates are usually evaluated through empirical or semiempirical
In this work a practical implementation of a real time optimization (RTO) in an industrial scale propylene-propane distillation process (Refinaria de Paulinia, SP, Brazil) owned by Petrobras S.A. is carried out. The main steps of a classical RTO cycl
