| titleOfInvention | Delayed coking process utilizing adsorbent materials |
| abstract | A delayed coking process for use in a delayed coking unit that includes at least one drum (12), the coking unit producing a coke product (16) that is retained in the drum and a coking product stream (14) that is introduced into a coking product fractionator (20) to produce at least a bottoms fraction (22), an intermediate fraction (24) and a light fraction (28), the process including the steps of: a. introducing a fresh hydrocarbon feedstock (18) containing undesirable sulfur and/or nitrogen compounds for preheating into the lower portion of the coking product fractionator (20); b. introducing at least a portion (24b) of the intermediate fraction (24) and at least one adsorbent material (32) that selectively adsorbs sulfur and/or nitrogen-containing compounds into a mixing zone (30) to form an adsorbent slurry stream (34); c. discharging the bottoms fraction (22) from the fractionator (20); d. adding all or a portion of the slurry stream (34) to the bottoms fraction (22) to form a mixed coking unit feedstream (38); e. introducing the mixed coking unit feedstream (38) that includes the adsorbent material into the coking unit furnace (40) for heating to a predetermined coking temperature; and f. passing the heated mixed feedstream (42) to the delayed coking drum (12) to produce the delayed coking product stream (14) and depositing the adsorbent material (44) having adsorbed sulfur and/or nitrogen compounds with the coke (16) on the interior of the delayed coking unit drum (12). |
