  • Patent number: 9404043
    Abstract: A device for introduction of primary combustion air into the primary heating space of a coke oven chamber admits primary air through ports in the top of a oven chamber or in the oven chamber walls above the door or in the chamber door or in several or all of the mentioned positions These ports have inserts that are equipped with spouts, with the spouts having an opening through which primary air is conducted at a chamfered angle onto the coke cake. The primary air from the opening ports in the coke oven chamber top streams to the coke oven at an angle of less than 90° and primary air from the opening ports in the chamber wall above the door or in the door streams to the coke oven at an angle of greater than 0°. Also shown is a method for use with the described device.

  • Patent number: 7578907
    Abstract: The present invention features a coke drum de-heading system that provides unique advantages over prior art de-heading systems, namely the de-heading of a coke drum without having to physically remove the head units. This is essentially accomplished using one of a variety of specially designed de-header valves that may be removably coupled to a coke drum much the same way a conventional head or flange unit would be attached. The de-header valve is equipped with, among other things, a valve closure and means for supporting a valve closure capable of forming a continuous contact seal during the coke manufacturing process. The means for supporting a de-header valve typically comprises a seat support system comprising a variety of configurational designs. Actuation of the valve closure functions to open and close the de-header valve, wherein in a closed position, the de-header valve and coke drum are prepared to receive the petroleum byproduct feed from the refinery process used to manufacture coke.

    Abstract: The present invention is directed to a photolytic cell, and to a photolytic artificial lung incorporating such a cell. The photolytic artificial lung converts water to oxygen for blood absorption, regulates pH, the removes carbon dioxide, and co-produces electrical power. The photolytic artificial lung includes a photolytic cell where all of the chemical reactions occur. Additionally, the present invention relates to photolytically sensitive materials for oxygen generation. These materials are useful for gas-free artificial lung and/or pulmonary capillary fabrication. The photolytic cell disclosed herein can also be used to direct chemical reactions in organs other than the lung.

  • 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).

  • Patent number: 7316762
    Abstract: The present invention features a flange to flange dynamic seal and sealing system, particularly suited for use within high temperature, high pressure environments, such as a delayed coking process. The dynamic flange seal and sealing system comprises two primary elements or seals, each of which are capable of independently forming a flange seal between two flanged components or combining to create a flange seal. Specifically, these primary seals are an iconel bellows seal and a bi-material gasket, each of which surround a flange opening along a sealing surface. The flange seal created by the dynamic flange seal and sealing system is capable of being maintained in light of, or rather the sealing system adapts to, any structural or environmental changes within the connected flanges. As such, the flange seal may be a dynamic flange seal or a static flange seal or both.

  • 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.
