Abstract:
For short-term scheduling of crude oil operations in a refinery, charging tanks are a type of critical resources. If the number of charging tanks is insufficient, the scheduling problem is further complicated. In this case, to make a refinery operate uninterruptedly, a charging tank has to be operated under a mode such that it is charged and at the same time used to feed a distiller for some time. Such a mode is called simultaneously-charging-and-feeding (SCF) mode, leading to disturbance to the oil distillation in distillers. Thus, the usage of such a mode should be as less as possible. To do so, a hybrid Petri net model is developed to describe the behavior of the system. Then, a scheduling method is proposed to find a detailed schedule for realizing a given refining schedule such that the SCF mode is minimally used. It is computationally efficient.
