The decoking control valve includes a piston, a cylinder, and a hydraulic rod seal at the outlet ports. The piston can move translational inside the cylinder along a fixed direction. The cylinder houses the hydraulic rod seal in a groove of the cylinder that places the hydraulic rod seal next to the piston. The hydraulic rod seal has a seal ring in contact with the piston, and the seal rings are activated. As the piston translates within the cylinder, the seal ring will activate at one outlet port and allow fluid to flow out of another outlet port.

In an embodiment, a de-heading device for a coke drum includes an outer component that includes an inlet nozzle; and an inner component that includes a pipe elbow and an orifice, wherein the outer component is coupled to the inner component by an actuator, the actuator for shifting between two or more positions. In another embodiment, a method of de-heading a coke drum includes actuating an actuator, the actuator coupled to a de-heading device, wherein the de-heading device includes an outer component comprising an inlet nozzle; and an inner component comprising a pipe elbow and an orifice, wherein the outer component is coupled to the inner component by the actuator, the actuator for shifting between two or more positions; and either removing a material from a coke drum coupled to the de-heading device, or filling a coke drum coupled to the de-heading device with a material.

An automatic dehydration, extraction and transportation apparatus for petroleum coke, includes a bottom cover device, crusher, coke chute and extracting device. The bottom cover device is at the bottom of a coke tower and connected to a coke storage pool via the chute. A grid net for filtering petroleum coke is horizontally provided in the lower part of the pool. A partition door is on an end, away from the chute, of a side pool wall of the pool. The extracting device enters and exits the coke storage pool through the partition door. A partition wall is between the partition door and the chute. The surface of the partition wall is opposite the chute, such that a corridor is formed between the other pool wall opposite the chute and the partition wall. One end of the partition wall is connected to the pool wall provided with the partition door.

An apparatus for raising and lowering a cutting tool within a decoking drum, a decoking system and a method of raising and lowering a decoking system cutting tool. Instead of using metallic ropes, chains, or a self-propelled gear-based approach, non-metallic belts are secured at respective ends to a crosshead and one or more counterweights to enable vertical movement of the crosshead that in turn permits vertical movement of the cutting tool throughout the height of the drum. A motorized pulley system controls the movement of the belt, and preferably avoids having the motor be carried by the crosshead. The belts on each pulley are preferably arranged as cooperative sets so that within each set, both primary load belts and secondary load belts are present. Enhanced engagement between at least the primary load belts and the pulleys promotes greater load-bearing capability, while the secondary load belts are sufficiently strong to ensure positional stability of the crosshead and decoking tool upon damage to or failure of one or more of the primary load belts.

An arrangement of a coke drum unit and of a coke crushing unit for use in a closed, gastight system for gaining sellable petroleum coke pieces out of solidified petroleum coke in a coke drum unit. It comprises a coke drum unit containing solidified petroleum coke; a coke crushing unit for crushing the petroleum coke into sellable petroleum coke pieces arranged below the coke drum unit; a lower funnel connected to the coke crushing unit and having an upper end portion; an upper funnel connected to the lower end of the coke drum unit and having a lower end portion with a smaller diameter than the upper end portion of the lower funnel; the lower end portion of the upper funnel extending into the upper end portion of the lower funnel; and at least one circumferential sealing element providing a gastight sealing between the upper funnel and the lower funnel and allowing for an axial and radial movement of the upper funnel with respect to the lower funnel.
