Reforming. The process of reforming was developed to raise both the quality and volume of gasoline produced by refiners. Using a catalyst again, after a series of reforming processes, substances are converted into aromatics and isomers, which have much higher octane numbers than the paraffins and napthenes produced by other refinery processes.

The process begins with heating crude palm oil (CPO) to a specific temperature, typically around 70-75°C (158-167°F). This heating reduces the viscosity of the oil, making it more fluid and easier to work with. Crystallization: After heating, the CPO is gradually cooled down under controlled conditions.
Before entering the refining process, crude oil must go through the pretreatment steps of dewatering and desalting and, in addition, undergo stabilization (removal of the main part of the associated gas) at the production field. After that, the stabilized oil is transported to the refinery with a minimum amount of water and salts.

A ladle furnace (LF) refining process model is proposed considering both steel mixing and multiphase chemical reactions. In the model, the LF, together with the melts, is divided into a finite number of tanks according to the tank-in-series model. The tank number is determined by simulations of the model with varied tanks and compared …
