Claims
- 1. A vapor-liquid contactor in which a liquid flows down along a surface of a packing and contacts ascending vapor in a column, which comprises:a) a structured packing, said structured packing being a non-promoting-fluid-dispersion structured packing in which various types of thin sheets or tubes for directing said liquid and vapor flows vertically are arranged to conform said flows vertically; and b) at least one liquid distributor consisting of a rough distribution part to distribute the liquid roughly and a minute distribution part to distribute the liquid minutely and equally.
- 2. The vapor-liquid contactor according to claim 1 wherein said non-promoting-liquid-dispersion structured packing has a specific surface area of 350 m2/m3 or more.
- 3. The vapor-liquid contactor according to claim 1 wherein said minute distribution part is formed with a structured packing, said structured packing being a self-promoting-liquid-dispersion structured packing.
- 4. The vapor-liquid contactor according to claim 1 wherein said minute distribution part consists of at least one of self-promoting-liquid-dispersion structured packing and at least one block of parallel plane sheets that are stacked in a column vertically.
- 5. The vapor-liquid contactor according to claim 1 wherein said non-promoting-liquid-dispersion structured packing comprises thin metal sheets or metal tubes.
- 6. The vapor-liquid contactor according to claim 1 wherein cross-sectional flow channels of said non-promoting-liquid-dispersion structured packing are angular.
- 7. The vapor-liquid contactor according to claim 1 wherein cross-sectional flow channels of said non-promoting-liquid-dispersion structured packing are triangular.
- 8. The vapor-liquid contactor according to claim 1 wherein cross-sectional flow channels of said non-promoting-liquid-dispersion structured packing are quadrangular.
- 9. The vapor-liquid contactor according to claim 1 wherein the cross-sectional flow channels of said non-promoting-liquid-dispersion structured packing are hexagonal.
- 10. The vapor-liquid contactor according to claim 1 wherein said non-promoting-fluid-dispersion structured packing comprises wavy thin sheets which have a curved surface.
- 11. The vapor-liquid contactor according to claim 1 wherein said non-promoting-fluid-dispersion structured packing has at least two types of cross-sectional flow channels selected from the group consisting of a triangle, a quadrangle and a hexagon.
- 12. The vapor-liquid contactor according to claim 1 wherein said non-promoting-fluid dispersion structured packing comprise a plurality of thin sheets arranged as spacers.
- 13. The vapor-liquid contactor according to claim 5 wherein said thin sheet has at least one selected from a group consisting of holes, flutings, grooves, and alternating-peaks-and-troughs.
- 14. The vapor-liquid contactor according to claim 1 wherein at least one vapor distributor is provided at the bottom of said non-promoting-dispersion structured packing.
- 15. The vapor-liquid contactor according to claim 14 wherein said vapor distributor is formed with a self-promoting-dispersion structured packing.
- 16. A cryogenic air separation unit comprising the vapor-liquid contactor according to claim 1.
- 17. The vapor-liquid contactor according to claim 8 wherein the cross-sectional flow channels of said non-promoting-liquid dispersion structured packing is selected from the group consisting of a square, rectangle, trapezoid, and rhombus.
- 18. The vapor-liquid contactor according to claim 12 wherein said spacer has at least one selected from the group consisting of holes, flutings, grooves, and alternating-peaks-and-troughs.
