SYSTEM AND METHOD FOR FLUIDIZED DIRECT REDUCTION OF IRON ORE CONCENTRATE POWDER

A system and method for the fluidized direct reduction of iron ore concentrate powder. A two-phase fluidized bed is used for the direct reduction of iron ore concentrate powder. Each phase of the fluidized bed is formed by a bubbling bed and a circulating bed. Use of serial-connection processing involving gas and of high-gas-velocity processing of the circulating bed increase the gas utilization rate and the reduction efficiency of single-phase reduction. Once reduced gases are subjected to preheating, each gas is sent into an initial reduction phase and a final reduction phase so as to implement reduction of minerals. Use of mixed-connection processing involving gas appropriately reduces processing pressure. Hot flue gas produced by combustion in a gas heater is sent to a mineral pre-heating system that is used for pre-heating iron ore concentrate powder.

FLUID BED APPARATUS FOR TREATING PARTICLE-SHAPED GOODS

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.

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.

Device and method for introducing oxygen into gasification process in fluidized formation under pressure

FIELD: machine engineering. SUBSTANCE: oxygen lance comprises three pipes arranged coaxially with respect to each other. An outer pipe 6 is arranged to pass the superheated steam 7. An inner pipe 2 leads to a middle pipe 4 and comes to a nozzle type cone before its mouth and is configured for passing oxygen 1 with temperature not exceeding 180°C. There is a temperature sensor 3 in the inner part of the inner pipe 2 that almost completely reaches the mouth of the outer pipe 2. The mouth of the middle pipe 4 further extends relative to the moth 8 of the outer pipe 6. The method for introducing oxygen into the fluidized-formation gasification reactor operated according to the Winkler method comprises supplying wet gas to the outer pipe under pressure by the oxygen lance exceeding the pressure in the fluidized-formation gasification reactor. The oxygen 1 is passed through the inner pipe 2 under a pressure higher than the pressure in the fluidized-formation gasification reactor. Wet gas is discharged from the mouth 8 of the outer pipe 6 as an external flow around the mouth of the middle pipe 4, and the free jet 10 is discharged. The flow velocity of discharged wet gas is higher than the velocity of the discharged gas from the inner pipe 2. EFFECT: invention makes it possible to provide efficient, safe and accessible introduction of oxygen into the gasification process in the fluidized formation under pressure above 10 bar as well. 14 cl, 2 dwg, 4 ex РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 635 631 C2 (51) МПК C10J 3/56 (2006.01) C21B 7/16 (2006.01) C21C 5/48 (2006.01) F27B 1/16 (2006.01) F27D 3/16 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (21)(22) Заявка: 2015106191, 08.08.2013 (24) Дата начала отсчета срока действия патента: 08.08.2013 Дата регистрации: (73) Патентообладатель(и): ТюссенКрупп Индастриал Солюшнс АГ (DE) Приоритет(ы): (30) Конвенционный приоритет: 14.08.2012 DE 10 2012 016 086.0 (45) Опубликовано: 14 ...

Direct reduction equipment and process

Method for treating powdered, especially metal containing initial material and apparatus for performing the same

FIELD: treatment of powdered, especially metal containing initial material introduced together with treating gas such as reducing gas for creating fluidized bed in fluidized bed chamber, for example in fluidized-bed reactor. SUBSTANCE: treating gas at least after partial conversion in fluidized bed is removed out of fluidized bed and then outside fluidized bed it is partially recovered, preferably oxidized due to performing chemical, namely exothermal reaction with gaseous and(or) liquid oxidizer. Heat energy of such reaction at least partially is fed to fluidized-bed chamber, especially to fluidized bed or it is taken out of it. Cyclone is arranged over fluidized bed in fluidized-bed chamber. Powdered initial material is heated or cooled in zone of cyclone, namely near inlet opening of cyclone due to using treating gas at least partially recovered over fluidized bed in fluidized-bed chamber, possibly heated or cooled, and(or) due to using system for recovering treating gas. EFFECT: possibility for decreasing caking on distributing collector of fluidized-bed reactor, lowered slagging in zone of fluidized bed. 10 cl, 1 dwg ÐÎÑÑÈÉÑÊÀß ÔÅÄÅÐÀÖÈß (19) RU (11) 2 298 453 (13) C2 (51) ÌÏÊ B22F 9/18 (2006.01) F27B 15/00 (2006.01) ÔÅÄÅÐÀËÜÍÀß ÑËÓÆÁÀ ÏÎ ÈÍÒÅËËÅÊÒÓÀËÜÍÎÉ ÑÎÁÑÒÂÅÍÍÎÑÒÈ, ÏÀÒÅÍÒÀÌ È ÒÎÂÀÐÍÛÌ ÇÍÀÊÀÌ (12) ÎÏÈÑÀÍÈÅ ÈÇÎÁÐÅÒÅÍÈß Ê ÏÀÒÅÍÒÓ (21), (22) Çà âêà: 2004117528/02, 23.10.2002 (72) Àâòîð(û): ÖÈÐÍÃÀÑÒ Éîõàíí (AT), ×ÅÒ×Å Àëüáåðò (AT) (24) Äàòà íà÷àëà îòñ÷åòà ñðîêà äåéñòâè ïàòåíòà: 23.10.2002 (43) Äàòà ïóáëèêàöèè çà âêè: 10.05.2005 (45) Îïóáëèêîâàíî: 10.05.2007 Áþë. ¹ 13 (85) Äàòà ïåðåâîäà çà âêè PCT íà íàöèîíàëüíóþ ôàçó: 09.06.2004 2 2 9 8 4 5 3 R U (87) Ïóáëèêàöè PCT: WO 03/040417 (15.05.2003) C 2 C 2 (86) Çà âêà PCT: EP 02/11828 (23.10.2002) Àäðåñ äë ïåðåïèñêè: 129010, Ìîñêâà, óë.
