Patent number: 10081766Abstract: A retractable center feed injection device can be employed to feed residual oil into a coke drum as part of a delayed coking process. The retractable center feed injection device can include a housing within which the injection nozzle slides between an extended and a retracted position. A feed inlet is positioned on an opposite side of the coke drum from the retractable center feed injection device. When in the extended position, the injection nozzle can couple with the feed inlet and thereby form an extension of the feed inlet into the center of the coke drum. In this way, the residual oil never flows through the housing.Type: GrantFiled: June 17, 2016Date of Patent: September 25, 2018Inventors: Ruben F. Lah, Kenneth Krause, Gary Larsen
