Embodiment Construction

[0046] It will be readily understood that the components of the invention, generally described and illustrated in the drawings, may be arranged and designed in widely varying configurations. Therefore, next more detailed system, device and method of the present invention and from Picture 1-1 The description of the embodiments represented by 1 is not intended to limit the scope of the invention as the claims are, but is merely representative of preferred embodiments of the invention.

[0047] The presently preferred embodiments of the present invention will be best understood by reference to the drawings, wherein like numerals refer to like parts throughout. Although reference is made to the drawings and related descriptions that follow immediately below, it has the first advantage of providing a general background on the coking process, including the de-heading process of the coke drum at the end of the production process.

Abstract

The present invention features a coke drum de-heading system (10) without having to physically remove the head units. This is accomplished using a specially designed dual seated, linear motion goggle blind gate valve, or de-header valve (12), that is removably coupled to and seals against the flanged (42) portion of a coke drum (18) much the same way a conventional head unit would be attached. The de-header valve (12) is equipped with, among other things, a sliding blind (122) that is contained and capable of moving within an upper (34) and a lower (38) seat, wherein one of such seats is a floating dynamic, live loaded seat that is capable of automatic adjustment through one or more loading zones so as to seal the blind (122) between the upper (34) and lower (38) seats. The movement of the sliding blind (122) serves to open and close the de-header valve (12), wherein in a closed position, the de-header valve (12) is prepared to receive the resid byproduct feed from the refinery process used to manufacture coke (4). Once the drum (18) is full, the de-header valve (12) may be actuated (opened), wherein the coke (4) that has accumulated on the blind (106) is sheared by the upper (34) and lower (38) seats, thus de-heading the coke drum (18) and facilitating the removal of coke (4) using methods commonly known in the art.

Description

technical field [0001] The present invention contemplates a system and apparatus for deheading vessels containing liquid, distillate, or unconsolidated debris by-products, such as various types of coke. In particular, the present invention contemplates a system and apparatus, namely a deheader valve, which is attached to the coke drum, particularly at the top or bottom opening, to allow safe and effective It can effectively de-head the coke drum and facilitate the removal of coke during the decarburization process. Background technique [0002] In the hydrocarbon processing industry, many refineries recover valuable products from the heavy residue remaining after refining operations are completed. This recovery process is called delayed coking and produces valuable distillate and coke in large vessels or coke drums. Coke drums are usually operated in pairs so that when one drum is filled with by-products or residual raw materials, the feed can be filled directly into the o...
