ABSTRACT
Delayed Coking Units (DCUs) are capable of processing bottom-of-barrel materials into valuable lighter products, increasing refineries’ profit margins and assuring the flexibility needed in a refinery scheme to keep up with the demand for light products. In Brazil, the increasing importance of DCU can be seen as a result of the heavy crudes production in the oil fields at Campos Basin and the large demand for diesel (Barros et al. 2003).
