摘要:
Multi Fluid Injection Mixer for injecting gas and/or liquid as admixture fluid to gas and/or liquid flowing through a pipe, and homogeneously mixing the admixture fluids and pipe fluids, said injection mixer constituting a section of the pipe, distinguished in that the injection mixer is comprising: at least one contacting element having at least one contacting surface facing and deflecting some of the pipe fluid flow, forming a constriction to the internal cross-section of the pipe, such that the pipe fluid flow is accelerated and fluid flowing in the vicinity of said surface is deflected to flow along the surface until the surface end over a sharp edge at the point of maximum constriction and flow velocity, at least one injection element arranged with a fluid connection to said surface of the contacting element, such that admixture fluid can be injected onto said surface and along said surface be entrained by the flowing pipe fluid over the sharp edge, but for a contacting element formed as a contracting pipe section at least two injection elements are provided.

Reactor vessel and a feed nozzle assembly for feeding a gas and a liquid into such reactor vessel. The feed nozzle assembly comprises an outer tube supplying a first liquid feed, such as oil, an inner tube supplying a dispersion gas, such as steam, a third tube supplying a second liquid feed, such as biomass, and a nozzle end. A catalytic cracking process wherein two or more hydrocarbon liquids are jointly dispersed into a dispersion gas and jetted via the same feed nozzle assembly into a catalytic cracking reactor.

The invention provides a mixing system comprising the following: A) at least one extensional flow mixer comprising: a generally open and hollow body having a contoured outer surface and having: a single entrance port and a single exit port; a means for compressing a bulk stream flowing through the generally open and hollow body in a direction of flow, and at least one injected additive stream introduced at the single entrance port in the direction of flow; and a means for broadening the bulk stream and the at least one injected additive stream, such that an interfacial area between the bulk stream and the at least one injected additive stream is increased as the bulk stream and the at least one injected additive stream flow through the generally open and hollow body in the direction of flow to promote mixing of the bulk stream and the at least one injected additive stream; B) a flow conductor having an axis and having a generally open and hollow flow mixer body cured therein; and C) a primary additive stream injector positioned at the entrance port of the generally open and hollow flow mixer body, wherein the primary additive stream injector injects an additive stream into the interior of the flow mixer in the direction of flow, when the bulk stream is flowing through the generally open and hollow flow mixer body, to allow for compression and broadening of the bulk stream and the additive stream together within the extensional flow mixer, to facilitate mixing of the bulk stream and the primary additive stream at an exit of the extensional flow mixer; and wherein the extensional flow mixer is followed by D) at least one helical static mixing element that is at least one half flow conductor diameter (D1) downstream of the exit of the extensional flow mixer.
摘要:
Vorgeschlagen wird ein Reaktor (1) zur Durchführung einer Reaktion zwischen zwei fluiden Edukten (2, 3) an einem Katalysatorbett (4) mit Vorvermischen der fluiden Edukte (2, 3) vor der Zuführung zum Katalysatorbett innerhalb einer Verzögerungszeit kleiner als 150 ms in einer Einmischvorrichtung (5), der dadurch gekennzeichnet ist, dass die Einmischvorrichtung (5) aus den folgenden Elementen gebildet ist, die im Wesentlichen quer zur Anströmrichtung des ersten fluiden Eduktstromes (2) angeordnet sind: - zwei oder drei hintereinander angeordnete Reihen von Rohren (6), mit Turbulenzerzeugern auf der Außenseite derselben die den Durchtrittsquerschnitt für den ersten fluiden Eduktstrom (2) auf 1/2 bis 1/10 verengen, wobei durch die Innenräume der Rohre (6) der zweite fluide Eduktstrom (3) geleitet und über Öffnungen (7) in den Rohren (6) in den ersten fluiden Eduktstrom (2) eingedüst wird sowie - einem den Rohren (6) vorgeschalteten Lochblech (10) und - einem den Rohren (6) nachgeschalteten Lochblech (11).
摘要:
An air pollution control device 10 according to the first embodiment of the present invention is an air pollution control device for reducing the amounts of NOx and Hg contained in flue gas 12 from a boiler 11. The air pollution control device includes: NH 4 Cl solution supply means 16 for spraying an NH 4 Cl solution 14 by a plurality of spray nozzles 15 into a flue gas duct 13 at the downstream of the boiler 11; a reduction-denitration device 18 including a denitration catalyst for reducing NOx in the flue gas 12 with NH 3 and for oxidizing Hg under the coexistence with HCl; and a wet desulfurization device 22 for reducing the amount of Hg oxidized in the reduction-denitration device 18 by using a limestone-gypsum slurry 21. The NH 4 Cl solution supply means 16 supplies the NH 4 Cl solution 14 from the spray nozzles 15 so as to prevent the NH 4 Cl solution 14 from being adhered to an inner wall of the flue gas duct 13 through which the flue gas 12 is flowing.
