  • Patent number: 7468118
    Abstract: A system for the extraction, drainage and wet transport of the petroleum coke produced by the coking chambers is described. Such system provides the collection, drainage and transport of the petroleum coke coming from the coking chambers during the cutting phase all the way to the boilers' feeding. The material extracted from the coking chamber (7) through the use of high pressure water is conveyed on the pre-crusher (4) through a connection system (1a). Between the pre-crusher (4) and the draining belt conveyor (2) there is a drainage and containment hopper (1) which has the dual function of accumulation and possible drainage thanks to some holes that serve as weir. The material which falls from above in different sizes, after having being reduced in size by the pre-crusher (4), gets transported by the belt (2) that carries out a first drainage phase through the holes made on the same belt. The coke is collected on the belt while the drained water is collected in a lower collection channel (8).

  • Publication number: 20080053814
    Abstract: A liquid distributor for use in a column having distillation trays has been developed. The liquid distributor functions to uniformly distribute a descending liquid stream across the tray for interaction with an ascending vapor stream. The liquid distributor has a feed pipe which delivers the liquid stream to an underlying elongated trough. Liquid discharge holes are positioned in the floor of the trough. A perforated v-plate positioned within the trough so that liquid from the feed pipe passes through the perforated v-plate before encountering the floor of the trough. When liquid passes through the perforated v-plate, the stream is divided into smaller streams of lower velocity, providing a more uniform overall flow rate of liquid passing through the trough. Liquid is then delivered from the discharge outlets of the trough onto the upper surface of the tray with a substantially uniform flow rate across the trough.

  • Publication number: 20040024279
    Abstract: An apparatus and method for processing hazardous wastes directly from 55-gallon drums through the use of pyrolysis and steam reforming. The method is based on a pyrolyzer using heat to vaporize organics that are present in the hazardous wastes. The waste is heated in the original drums to avoid the bulk handling of alpha radionuclides and to ensure criticality control. At pyrolysis temperatures, all liquids and organics in the drums will evaporate and volatize. The resulting waste in the drums is a dry, inert, inorganic matrix with carbon char containing radioactive metals. The off-gas produced by pyrolysis mainly consists of water vapor, volatized organics, and acid gases from the decomposition of various plastics and other organics present in the waste drums. The off-gas produced by the pyrolysis is then collected and fed into an off-gas treatment system that is in fluid communication with pyrolyzer operated under oxidizing conditions.

Said steam is confluent with steam generated by combustion of said Hydrogen and Oxygen. Net steam flow is used externally for generating power, heating and cooling purposes.

  • Patent number: 6395139
    Abstract: There is provided a feed distributor for feeding liquid to a liquid distributor. The feed distributor has an elongated body sized to extend across the liquid distributor and an inlet defined in the one of the ends thereof. One or more passageways are provided within the body extending between the ends of the body. Each passageway has an elongated outlet configured to discharge the liquid across the liquid distributor. Each passageway has a taper configured to promote a constant liquid velocity within the passageway. As a result, a uniform liquid distribution of the liquid out of the elongated outlet and therefore to the liquid distributor are promoted.

  • Publication number: 20020023829
    Abstract: A coke drum head is hinged to a coke drum body using a compound joint such as a trammel pivot, and the head is moved between open and closed positions using an actuator. In moving between open and closed positions, the head traces out a non-circular path which reduces the required headroom relative to a head using a standard pivot.

  • Publication number: 20010032780
    Abstract: The present invention relates to an apparatus and method for withdrawing and dewatering slag from a gasification system. In particular, the present invention relates to a conveying lockhopper and method of using the conveying lockhopper to collect slag and other waste byproducts from the gasifier of a gasification system. The conveying lockhopper is configured to receive slag from a gasifier, simultaneously extract and dewater the slag, and expel the processed slag directly into an awaiting container suitable for carrying the processed slag away. The conveying lockhopper generally comprises a housing with inlet and outlet valves to receive and expel slag, respectively. The housing is inclined at an angle typically between 5 and 60 degrees to the horizontal so that the outlet is at a higher elevation than the inlet. Inside the housing, an auger or similar conveying mechanism conveys the slag from the inlet towards the outlet while simultaneously dewatering the slag.

  • Patent number: 6290494
    Abstract: The invention provides a coke oven charging machine including a mobile frame and a coke oven feed device on the mobile frame. The coke oven feed device includes a movable, elongate charging plate having a first end and a second end, retractable side-walls adjacent the charging plate, first and second end walls adjacent the first and second ends of the charging plate and a shuttle section adjacent the first end of the charging plate for spanning an area between the first end of the charging plate and an entrance to the oven. The shuttle section has opposed shuttle side walls and a shuttle end wall. A charging plate moving device is provided for moving the charging plate into and out of the oven. The charging machine apparatus provides a means for quickly charging coking ovens with a compacted coal charge so that lower quality coals may be used to make metallurgical coke.

  • Patent number: 6113745
    Abstract: Methods and compositions are provided which decrease the risk and spillage associated with discharging coke from a coking vessel. The risk to workers is decreased by eliminating the need for workers to be near the coking vessel while the head is being removed. The spillage is decreased by modifying the effective diameter of the coke chute inlet in a manner which allows it to catch any materials discharged from the coking vessel both during and after the opening of the bottom head. The process can enhance drum draining and further eliminate the need for process piping to facilitate the draining of water from the coking vessel.

  • Patent number: 6051110
    Abstract: In apparatus for thermolytic distillation of lump carbonaceous material, an enclosure contains a degassing bath, a reactor bath and a quenching bath. A closed loop continuous chain conveyor drives a plurality of baskets carrying carbonaceous material through the three baths of the enclosure. The carbonaceous material is degassed in hot distillate, then immersed in molten lead in the absence of oxygen to produce char and vapor by thermolytic distillation. The char is quenched with water in the absence of oxygen. At least a portion of the vapor is condensed to produce combustible distillate.
