METHOD FOR PRODUCING A COKING ADDITIVE BY DELAYED COKING

This invention relates to the field of oil refining and, in particular, to a delayed coking process that produces coke with a volatile substances content of 15-25% for use as a coking additive in a coal coking charge in the production of metallurgical coke. The invention is directed towards increasi...

Beschreibung
Zusammenfassung:	This invention relates to the field of oil refining and, in particular, to a delayed coking process that produces coke with a volatile substances content of 15-25% for use as a coking additive in a coal coking charge in the production of metallurgical coke. The invention is directed towards increasing the content of volatile substances in coke and increasing the efficiency of a plant. The method comprises preheating a primary raw material, mixing the latter with recycle in a tank in order to form a secondary raw material, heating the secondary raw material to 455-470° C. and supplying the latter to a coking chamber, and coking to form a coking additive. It is expedient to feed an antifoaming additive into the coking chamber 3-5 hours before coking is finished. It is preferable to feed in the antifoaming addition agent at two-four points around the perimeter of the coking chamber.
