Method and apparatus for compacting coal for a coal coking process

Номер: US20120030998A1
Принадлежит: Sun Coke Co

Relatively high speed methods for increasing the bulk density of coal particles without impacting the coal particles and an apparatus for compacting coal for making metallurgical coke. The method includes depositing coal particles onto a charging plate external to a coking oven. The charging plate has side walls, and at least one movable end wall to provide an elongate bed of dry, uncompacted coal having an upper surface on the charging plate. The uncompacted coal is compacted by passing a vibratory cylindrical compactor along a length of the uncompacted coal for a number of passes sufficient to decrease a thickness of the bed of coal to less than about 80 percent of an original thickness of the uncompacted coal. The vibratory cylindrical compactor has a length to diameter ratio ranging from about 1.4:1 to about 2:1.

CONTROLLING COKE MORPHOLOGY WITH SULFUR

Номер: US20210301211A1
Принадлежит:

Systems and methods are provided for controlling the morphology of coke produced during delayed coking. The morphology control is achieved in part by introducing elemental sulfur into the coker feedstock prior to coking. The elemental sulfur can be introduced into the feed under conditions so that the sulfur is well-dispersed within the feed for a sufficient period of time. This can allow for relatively even reaction of sulfur with components throughout the feed, resulting in a relatively small, uniform domain size distribution for the coke produced during delayed coking. This coke can correspond to shot coke. By producing coke with a small and relatively uniform domain size distribution, the risk of uneven heating within the coke can be reduced or minimized. 1. A method for controlling coke morphology during delayed coking , comprising:providing a coker feedstock that forms transition coke under standard delayed coking conditions;mixing the coker feedstock with 0.5 wt % to 5.0 wt % of elemental sulfur to form a mixed coker feedstock;maintaining the mixed coker feedstock at a temperature of 160° C. to 260° C. for 2.0 hours to 5 days to form a treated coker feedstock; andexposing the treated coker feedstock to second delayed coking conditions to form a coker effluent and treated coke comprising shot coke.2. The method of claim 1 , wherein the treated coke further comprises a lognormal domain size distribution having a value of a shape parameter σ of 0.30 or less and a value of a location parameter μ of 1.85 or less.3.

Method of charging coke oven with coal

Номер: DE19545736A1
Принадлежит: Thyssen Still Otto Anlagentechnik GmbH

A bottom-heated coking oven is filled with coal by a method in which the coal outside the oven is dumped on to a base plate at uniform height and then compacted, the plate and compacted coal cake being pushed into the oven chamber. The plate is then removed. The coal cake is 500-1000 (600-800) mm high. Also claimed is an operating machine, which can be moved along a row of adjacent coking ovens, having a base plate (3) of the dimensions of the oven base which forms a shallow and large-area coal filling and compaction chamber with side walls (9, 10) and front and rear side walls. When the coal is charged into the oven chamber, the rear end wall and the base can be moved in the longitudinal direction jointly with the base plate.

Coking coal compacting - by projection into mould through blades of centrifugal impellers, reduces machine stresses

Номер: DE2922861A1
Автор: Gerd Dipl Ing Veit
Принадлежит: SAARBERG INTERPLAN GmbH

A fine-grained coal blend which is to be used for charging coke ovens is compressed by transferring the coal blend from a continuous conveyor to one or more impellers, each with one or more blades. The impellers revolve opposite to the direction of free fall of the coal particles so that they are compacted into clumps. The centrifugal force accelerates the clumps and projects them into a compression mould, thus effecting a further compression by impact. Several impellers can be arranged on the same drive shaft, or several shafts, each with one or more impellers, can be arranged in parallel one after another. This method produces much less noise than the conventional stamping system. It results in less high stresses for the machine and mould use for the compaction; large quantities of a coal blend can be compressed in a very short time.

Method of producing petroleum coke (embodiments)

Номер: RU2719849C1

FIELD: oil, gas and coke-chemical industries.SUBSTANCE: invention relates to oil refining industry, particularly, to methods of producing petroleum coke by delayed coking oil stock with different content of volatile substances. Method involves heating of the coking raw material, its supply to the additional column with formation of secondary raw material with its further heating to 475 °C, supply to the coke chamber and fractionation of gas-vapour coking products in the rectification column. At that, according to the first embodiment of coke production with increased content of volatile substances, heat carrier - mixture of heavy and bottom-gas coke gasoil is heated in furnace to temperature of 510 °C, Then, it is supplied into reaction chamber and then through reduction valve with pressure of 0.1 MPa higher than in coke chamber, and temperature not lower than that of coking feed is supplied to bottom of coke chamber. According to the second embodiment, to produce coke with low content of volatile substances, a heat carrier with temperature of 510 °C is introduced into a hot feed stream with temperature of 505 °C, and then is fed into a coke chamber.EFFECT: technical result is higher output of components of motor fuel and higher efficiency of coking plant.6 cl, 1 tbl, 1 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 719 849 C1 (51) МПК C10B 55/00 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (52) СПК C10B 55/00 (2020.02) (21)(22) Заявка: 2019114639, 13.05.2019 (24) Дата начала отсчета срока действия патента: Дата регистрации: (73) Патентообладатель(и): Акционерное общество "Институт нефтехимпереработки" (АО "ИНХП") (RU) 23.04.2020 (45) Опубликовано: 23.04.2020 Бюл. № 12 2 7 1 9 8 4 9 R U (54) Способ получения нефтяного кокса (варианты) (57) Реферат: Изобретения относятся к нефтеперерабатывающей промышленности, в частности к вариантам способа получения нефтяного кокса замедленным коксованием нефтяного сырья с ...
