An apparatus and process for thermally de-manufacturing tires and other materials. The apparatus is a retort chamber with various zones in which tires are combusted to provide energy for the thermal depolymerization reaction, depolymerization takes place, and products leave the retort chamber. In one embodiment, the process reacts water with iron present in steel-belted tires to produce hydrogen, which helps to break sulfur-sulfur bonds in vulcanized materials. The water also helps control the temperature of the reaction, which allows for control over the types and relative amounts of the various depolymerization products.

The present application discloses a gas sampling device, in particular, a fractionation gas sampling device comprising a heat exchanger, and the heat exchanger comprises one or more groups of tubes, wherein, a guide plate is disposed in the tubes. The fractionation gas sampling device further comprises a coke cleaning mechanism having a decoking head, and the decoking head has a circular arc guide. The fractionation gas sampling device has a large heat exchange area, a high heat exchange efficiency, and overcomes the surface tension between liquids so as to avoid generating liquid columns; moreover, by combining with the coke cleaning mechanism, the fractionation gas sampling device not only achieves excellent technical effects relevant to decoking, but also effectively prevents from a blocking phenomenon of the decoking head, thereby realizing an automatic cleaning.

Systems and methods are provided for coke removal from the coke drum vapor line and/or other conduits between the coke drum and a coker product separation stage, such as a fractionator. A hydro-lance is inserted above the coke drum vapor line in the region where coke removal is desired. The hydro-lance can be inserted through a port, so that the lance is not present during coker operation. The hydro-lance can remove coke from the coke drum line during the water quench (flooding) stage of the coke drum process and/or during the draining step following the quench water cooling step of the coke drum.

Systems and methods for safe on-line pigging decoking of a coker furnace tubes and which also permits on-line spalling operations.

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.

The present subject matter describes a method and apparatus for operating a delayed coker. The method comprises contacting a vapour produced in a delayed coker-drum with a catalyst maintained in form of a bed, and maintaining a level of said catalyst-bed within pre-defined limits during catalytic-cracking of the vapour. Thereafter, the cracked-vapour is routed to a coker-fractionator column to trigger conversion into one or more hydrocarbon products.

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.
