Non-metallic belt-driven crosshead drive system for hydraulic decoking

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.

Solid inert residue (SIR) dryer and extractor system

Plastic conversion vessels such as pyrolytic reactors convert plastic waste materials such as polymers, or hydrocarboneous material, or both, via in situ chemical reactions comprising cracking, recombination, reforming, recracking, and the like, to usable chemical compounds such as naphtha, diesel fuel, heavy oil, wax, and the like. Inherent within the polymers and/or carbonaceous material are generally solid, inert residues such as various fillers, pigments, flame retardants, silica, aluminum, talc, glass, clay, and so forth. Such solid inert residues (SIR) must be treated to remove residual volatile organic material therefrom in order to meet acceptable environmental standards and/or limits. A heated dryer for treating the SIR comprises heating units to remove excessive volatile organic material therefrom as when moved along a conveyor that transfers said material to a collection area. The collection area comprises one or more pistons that are capable of compacting and discharging said SIR material. Another collection area embodiment comprises a plurality of plungers that transfer the SIR material from said collection area to a plunger collection area, and subsequently to a collection container.

Decoking control valve using dynamic rod seal

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.
