Advanced elevated feed distribution system for very large diameter RCC reactor risers

An FCC process and apparatus may include injecting hydrocarbon feedstock at different radial positions inside a riser. Multiple distributors may be used to position the openings for injecting feedstock at multiple radial positions. In addition, the openings may be away from riser peripheral wall and at different elevations along the riser wall or extending up from the riser bottom. The different opening positions introduce the feedstock across a larger area of the cross-section of the riser, which may improve the feedstock dispersion and mixing with catalyst. Improved mixing may increase conversion of the feedstock. Larger FCC units generally have greater riser diameters that may cause problems for feedstock dispersion and decrease the ability for the feedstock to mix with catalyst. Injecting the feedstock at multiple radial positions may improve feedstock dispersion in larger FCC units and increase mixing.

When placed at the bottom, the amount of reaction completed to match the supply of fresh raw material enters the separation section 22, where the flow rate of gas is slower than the minimum speed required to support the fine particles, and passes through the gas flow path. Will be discharged out.

Method for processing material in the form of particles and apparatus for performing the same

FIELD: processing procedures, mainly reducing material in the form of particles at least in one fluidized bed zone at elevated temperature, for example reduction of finely disintegrated ore. SUBSTANCE: material in the form of particles is held in fluidized zone by means of flow of processing gas passing from below to upwards. Fine-grain material passing from fluidized zone by action of processing gas is separated from processing gas in separation zone. In said zone next operations are realized: flow of processing gas and fine-grain material are fed to separation apparatus; fine-grain material is separated from processing gas due to removing processing gas out of separation apparatus as exhaust gas. Then fine-grain material is removed from separation apparatus and large-grain material is supplied to separation zone. EFFECT: lowered agglomeration degree, reduced quantity of deposits. 30 cl, 7 dwg ÐÎÑÑÈÉÑÊÀß ÔÅÄÅÐÀÖÈß (19) RU (11) 2 289 633 (13) C2 (51) ÌÏÊ C22B 1/10 (2006.01) C21B 13/00 (2006.01) C22B 5/14 (2006.01) ÔÅÄÅÐÀËÜÍÀß ÑËÓÆÁÀ ÏÎ ÈÍÒÅËËÅÊÒÓÀËÜÍÎÉ ÑÎÁÑÒÂÅÍÍÎÑÒÈ, ÏÀÒÅÍÒÀÌ È ÒÎÂÀÐÍÛÌ ÇÍÀÊÀÌ (12) ÎÏÈÑÀÍÈÅ ÈÇÎÁÐÅÒÅÍÈß Ê ÏÀÒÅÍÒÓ (21), (22) Çà âêà: 2004101037/02, 28.05.2002 (30) Êîíâåíöèîííûé ïðèîðèòåò: 19.06.2001 AT A948/01 19.06.2001 AT A949/01 (73) Ïàòåíòîîáëàäàòåëü(è): ÔÎÅÑÒ-ÀËÜÏÈÍÅ ÈÍÄÓÑÒÐÈÀÍËÀÃÅÍÁÀÓ ÃÌÁÕ ÓÍÄ ÊÎ (AT) R U (24) Äàòà íà÷àëà îòñ÷åòà ñðîêà äåéñòâè ïàòåíòà: 28.05.2002 (72) Àâòîð(û): ÍÀÃËÜ Ìèõåëü (AT), ØÅÍÊ Éîõàííåñ (AT), ×ÅÒ×Å Àëüáåðò (AT) (43) Äàòà ïóáëèêàöèè çà âêè: 10.06.2005 2 2 8 9 6 3 3 (45) Îïóáëèêîâàíî: 20.12.2006 Áþë. ¹ 35 (56) Ñïèñîê äîêóìåíòîâ, öèòèðîâàííûõ â îò÷åòå î ïîèñêå: JP 01-242708 À, 27.09.1989.

Apparatus and method for top removal of granular and fine material from a fluidized bed deposition reactor

유동층 증착 반응기로부터 과립상 물질의 상부 제거를 위한 장치 및 방법이 개시되어 있다. 반응기 상부로부터의 생성물의 제거는 분리 높이를 감소시킬 수 있고 층의 중량과 높이를 증가시키는 증착에도 불구하고 층 높이를 제어하는 패시브 수단을 제공한다. 분리 높이를 감소시키는 절약은 보다 짧은 전체 반응기 길이에서 보다 큰 유동층을 사용하게 하여, 반응기 비용을 감소시키면서 생산을 증가시킨다. 생성물 출구로부터 가스 입구의 분리는 가스 입구 영역이 생성물 출구보다 더 냉각되게 한다. 생성물 출구로부터 입구 가스에 의해 야기되는 생성물 연마의 분리는 생성물에서 시드의 손실을 감소시켜 보다 균일한 생성물을 생성한다. 동일한 장소에서 고온의 생성물과 고온의 가스의 제거는 단일의 단계에서 양자로부터 에너지를 회수하게 한다. An apparatus and method for top removal of granular material from a fluidized bed deposition reactor is disclosed. Removal of the product from the top of the reactor provides a passive means of reducing the separation height and controlling the layer height despite deposition which increases the weight and height of the layer. The savings in reducing the separation height allow the use of larger fluidized beds in shorter overall reactor lengths, increasing production while reducing reactor costs. Separation of the gas inlet from the product outlet allows the gas inlet area to be cooled more than the product outlet. Separation of the product polishing caused by the inlet gas from the product outlet reduces the loss of seed in the product and produces a more uniform product. Removal of hot products and hot gases at the same location allows energy to be recovered from both in a single step.

Heat removal and recovery in biomass pyrolysis

Pyrolysis methods and apparatuses that allow effective heat removal, for example when necessary to achieve a desired throughput or process a desired type of biomass, are disclosed. According to representative methods, the use of a quench medium (e.g., water), either as a primary or a secondary type of heat removal, allows greater control of process temperatures, particularly in the reheater where char, as a solid byproduct of pyrolysis, is combusted. Quench medium may be distributed to one or more locations within the reheater vessel, such as above and/or within a dense phase bed of fluidized particles of a solid heat carrier (e.g., sand) to better control heat removal.

Communicating compartmentalized fluidized bed reactor

A reactor configuration for fluidized bed reactors in which large exposed fixed surface area per unit reactor volume is required. The configuration uses a serpentine or hairpin bend arrangement of continuously connected and communicating thin channels, with the containing surfaces of these channels being vertical. This configuration enables uniform fluidization of particles throughout the cross-sectional area of the reactor and facilitates dispersal of membrane surfaces, heat transfer surface and baffles in gas-solid fluidized bed reactors.

В способе обработки измельченного материала в псевдоожиженном слое измельченный материал поддерживают в псевдоожиженном слое при помощи обрабатывающего газа, проходящего снизу вверх, и за счет этого обрабатывают. Обработке подвергается измельченный материал с широким распределением размеров зерна, имеющий относительно высокое содержание мелких частиц, а скорость обрабатывающего газа в свободном сечении в псевдоожиженном слое поддерживают меньшей, чем скорость, которая требуется для псевдоожижения самых крупных частиц упомянутого измельченного материала, при этом и крупные, и мелкие частицы перемещаются вверх и их выгружают через верхнюю область псевдоожиженного слоя. Скорость газа поддерживают в диапазоне 0,25-0,75 скорости, которая требуется для псевдоожижения самых крупных частиц. После предварительной обработки руду подают в плавильно-газификационный аппарат, где плавят с одновременным образованием восстановительного газа. Реализация изобретения позволит минимизировать потребление обрабатывающего газа и снизить унос мелких частиц обрабатывающим газом. 2 с. и 4 з. п. ф-лы, 3 ил.

The present invention is directed to an indirect-fired, stationary tube, gas/solids or solids/solids, full ceramic pyroprocessing furnace-reactor that uses heat-resistant conveyors to propel solids through the stationary tube.

Installation for thermal treatment of suspended powder substances, and use for flash calcining of mineral, in particular clayey, substances

The invention concerns an installation for quick thermal treatment of suspended powder substances, in particular for flash calcining of mineral substances. Said installation comprises modules (M1, M2, M3) advantageously arranged in mobile units including means supplying powder substances, a combustion chamber (21) wherein the substances are introduced suspended in a hot air flux and a cooling assembly (M3) where the calcined substances are recuperated to pre-heat the combustion air. The substances are pneumatically transported in the heated air downstream of the supplying means, via a pre-heating device (17) up to the combustion chamber (21).
