摘要： 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.

摘要： The present disclosure concerns a pyrolysis residue-discharge system fluid-tightly connectable to a pyrolysis reactor delimiting a fuel-containing cavity and having a discharge opening extending therethrough, the pyrolysis residue-discharge system comprising a residue discharge duct defining a residue discharge passageway having an inlet port and an outlet port; and a reactor-connecting end portion having a through opening, the reactor-connecting end portion being fluid-tightly connectable to the pyrolysis reactor to fluidly connect the through opening of the reactor-connecting end portion with the discharge opening of the pyrolysis reactor, the reactor-connecting end portion being fluid-tightly connectable to the residue discharge duct at the inlet port thereof to provide a fluid communication between the fuel-containing cavity of the pyrolysis reactor and the residue discharge passageway via the discharge opening. It also concerns a corresponding pyrolysis reactor assembly and a pyrolysis residue discharge method.

摘要： A method of removing an obstruction of coke built up in a riser of a fluid catalytic converter and of cleaning the riser involves using a suspended centralizer and narrowly angled nozzles for first hydroblasting a drainage orifice in the obstruction, adjusting guide arms and manipulating the suspended apparatus to allow enlargement of the orifice, further adjusting the guide arms and enlarging the angles of the nozzles to work the remaining coke built up.

摘要： A material transfer system for transferring material into or out of a pyrolysis system is described. The system includes a first conduit comprising a first inlet and a first outlet. a store, and a second conduit comprising a second inlet and a second outlet. The first conduit is configured to receive, at the first inlet, the material and transfer the material, through the first outlet, to the store. The store is configured to store the material. The second conduit is configured to: receive, at the second inlet, the material, transfer the material, and output the material through the second outlet.

摘要： 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.

摘要： 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.

摘要： A fluid jet nozzle for a decoking tool, a decoking tool and method of operating same. The nozzle includes a nozzle assembly for use in a fluid jet decoking tool. The assembly includes a housing to hold one or more nozzles that are used to spray or otherwise distribute decoking fluid. An internal flowpath that extends from an inlet of the nozzle to an outlet of the nozzle defines a tapered shape such that when the decoking fluid passes through the nozzle, the flowpath produces a predominantly coherent flow pattern in the fluid.
