Co-production of anode and fuel grade petroleum coke in a delayed coker unit

摘要

Co-production a product anode grade coke and a product fuel grade coke is done using a system configured to implement a method that includes: directing an anode grade coker charge material from a tower to a first coke drum set; generating the product anode grade coke using the first coke drum set while directing a first vapor stream from the first coker drum set to the tower; directing a fuel grade coker charge material from a fractionator to a second coke drum set; generating the product fuel grade coke using the second coke drum set while directing a second vapor stream from the second coke drum set to the fractionator; and directing a third vapor stream from the tower to the fractionator while generating the product anode grade coke using the first coke drum set and generating the product fuel grade coke using the second coke drum set.
