Abstract (en)

Methods for producing oil coke, using delayed coking, are described. A primary feed is heated and charged into a remote stripper of a rectification column, where it is mixed with heavy gasoil as a recirculant and where a secondary feed is produced, which is then heated in a reaction/heating furnace and transferred to a coking chamber, where a coking additive and vapour/liquid coking products are produced. The latter ones are fractionated in the rectification column, forming gas, benzene, light and heavy gasoil and coking bottom products. Calcium oxide/hydroxide is mixed with the secondary feed, and then mixed with heavy gasoil, before being transferred to the coking chamber. Alternatively, calcium oxide/hydroxide is added to the coking bottom products, mixed with heavy gasoil, after which the coking bottom products are either mixed with the secondary feed before feeding it into the coking chamber or they are introduced into the coking chamber directly.
