摘要:
Structured elements with capabilities for stream flow division and distribution and mitigation of undesired species that exceed those of conventionally available materials are provided. The structured elements provide increased opportunities for surface attraction, retention and coalescence of undesired species in a process stream. The functional contact surfaces of the structured elements can include one or more of the faces of cells, the surfaces of struts connecting cells, the surfaces of nodes connecting struts, and the surfaces of asperities or irregularities caused by channels, flutes, spikes, fibrils or filaments in or on the material surfaces.

The present invention relates to a device that conditions high entrance velocity, superheated feed gas, which include some high boiling components, for example, asphaltenes and poly-nuclear aromatics that tend to coke upon condensation and exposure to the superheated feed gas temperature. Also included in superheated feed gas are solid catalyst fines, from a single or multiple feed nozzles to a quiescent flow regime for uniform distribution of the gases, to a contact device within the Main Fractionator (MF) column.

Die Erfindung betrifft einen Kolonne, mit: einem entlang einer Längsachse (L) erstreckten Mantel (10), der einen Innenraum der Kolonne (1, 2, 3, 4) umschließt, zumindest einem Stoffaustauschboden (100), der sich entlang eines quer zur Längsachse (L) verlaufenden Kolonnenquerschnitts (Q) der Kolonne (1, 2, 3, 4) erstreckt, und zumindest einem Flüssigkeitsverteiler (200, 300), der dazu ausgebildet ist, den mindestens einen Stoffaustauschboden (100) mit einer flüssigen Phase (F) zu beaufschlagen. Erfindungsgemäß ist vorgesehen, dass der Stoffaustauschboden (100) eine Mehrzahl an parallel und beabstandet zueinander verlaufenden Ablaufelementen (101 ), insbesondere in Form von Winkelprofilen, aufweist, die sich jeweils entlang des Kolonnenquerschnitts (Q) erstrecken, wobei die Ablaufelemente (101 ) jeweils eine erste und eine zweite entlang des Kolonnenquerschnitts (Q) erstreckte Ablauffläche (102a, 103a) aufweisen, und wobei die beiden Ablaufflächen (102a, 103a) entlang der Längsachse (L) in Richtung auf den Flüssigkeitsverteiler (200, 300) aufeinander zu laufen und unter Ausbildung einer entlang des Kolonnenquerschnitts (Q) erstreckten Kante (104) aufeinandertreffen, und wobei der Flüssigkeitsverteiler (200, 300) dazu ausgebildet ist, die flüssige Phase (F) auf die Kanten (104) der Ablaufelemente (101 ) aufzugeben, so dass die auf das jeweilige Ablaufelement (101 ) aufgegebene flüssige Phase (F) zu beiden Seiten der jeweiligen Kante (104) über die Ablaufflächen (102a, 103a) vom jeweiligen Ablaufelement (101) abfließt.
摘要:
Systems and methods are provided for reducing maldistribution of liquids and vapors in packed towers. An exemplary separation system includes a separation tower including at least two packed beds, and a vapor redistribution plate disposed between two sequentially disposed packed beds, wherein the vapor redistribution plate is configured to mix a vapor from a lower packed bed before introducing the vapor into an upper packed bed.

The present invention relates to a feed distribution device in separation columns and a method of operation. In particular it relates to distillation columns in which the feed stream is substantially liquid phase, or a mixture of gas and liquid upstream of the column, but where the feed vaporizes or vaporizes prior to or as it enters the column. More specifically, the feed distribution device contains a plurality of opening which allow the feed to vaporize prior to or as it enters the column and where the openings are maintained in critical condition during operation. Significant advantage is achieved through the implementation and use of the present feed distribution devices.

One exemplary embodiment may be a distribution tray for a vessel. Generally, the distribution tray includes a member, a compartment, and an insert. The member can form a first side and a second side. Typically, the first side is adapted to receive a liquid thereon. Additionally, the member can form a plurality of openings. Usually, the compartment extends through the member with a first portion protruding from the first side and a second portion protruding from the second side, and is adapted to permit the passage of a fluid therethrough. The insert may be positioned within the compartment to constrict and then expand the passage of the fluid therethrough.
摘要:
A fluid delivery apparatus is provided for supplying a fluid mixture to a distillation column or reactor. The apparatus can be used to enhance the heat duty, the flow and/or the flow stability of an existing thermosiphon reboiler which supplies a heated fluid to the column or reactor. The apparatus includes an integrated eductor which receives and increases the fluid velocity of a supplemental fluid into which the heated fluid is aspirated to form a fluid mixture then delivered to the column or reactor. A process and a system utilizing the apparatus are also disclosed, as well as a method of retrofitting an existing system with the apparatus.
摘要:
A column structure (21) is described for the containment of high surface area packing and absorbent liquid reagent for the removal of a target gas from a gas stream. The column structure (21) comprises at least one vessel having an elongate upright wall structure (15) to define an absorption process volume for the containment of high surface area packing and for the countercurrent flow of absorbent liquid reagent and target gas in use; and a column perimeter structure (22) comprising an elongate upright wall structure disposed around the at least one vessel in such manner that an inner wall of the elongate upright wall structure and an outer wall of a vessel cooperably define and fluidly enclose at least one secondary fluid volume fluidly isolated from the absorption process volume (s). A method of assembly of such a column and to a method of removal of a target gas from a gas phase using such a column are also described.
摘要:
Methods are disclosed for the selective absorption of gas components based on differences in their gas phase and liquid phase resistances to mass transfer. The methods advantageously utilize a gas-liquid contacting apparatus having contacting stages with co-current flow channels that can provide contacting with increased liquid phase resistance to mass transfer, for example in the spray regime such that the liquid is effectively dispersed as small droplets into the gas phase.
