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 invention features a coke canister deheading system (10) that does not actually remove the head unit. This is accomplished by using a specially designed double fixed linear moving eye guard valve or deheader valve (12) which is detachably attached to the flanged portion (42) of the coke drum (18) and make it airtight the same way a conventional head unit is attached to it. The deheading valve (12) is equipped with a sliding baffle (122) contained and movable between an upper (34) and a lower (38) seat, one of which is floating Dynamic real-time load bearings of the present invention, which can be automatically adjusted through one or more load zones to seal the baffle (122) between the upper (34) and lower (38) bearings. The movement of the sliding baffle (122) is used to open and close the deheading valve (12). When it is in the closed position, the deheading valve (12) is ready to receive the incoming gas from the refining process for the production of coke (4). Residual by-products. Once the tank (18) is full, the deheader valve (12) can be actuated (opened) and the coke (4) accumulated on the baffle (106) is sheared by the upper (34) and lower (38) seats. to de-head the coke drum (18) and facilitate removal of the coke (4) using methods generally 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...
