Abstract

A contactor for a heat and/or material exchange column includes an arrangement of two structured packings developing different geometric surface areas and having parallel principal directions.
A heat exchange column, a floating structure including such a contactor, and the use of a column equipped with such a contactor are also disclosed.

First claim

The invention claimed is:

1. A contactor for a column intended for heat and/or material exchange between two fluids, comprising at least one packing layer comprising an arrangement of at least a first structured packing and a second structured packing, the second structured packing developing a specific geometric surface area, expressed as a geometric surface area of the packing per volume unit, greater than the specific geometric surface area of the first structured packing, the first structured packing has a principal direction through and along hollows between corrugations of plates of the first structured packing corresponding to an orthogonal direction to a vertical axis, the second structured packing has a principal direction passing through and along hollows between corrugations of plates of the second structured packing corresponding to an orthogonal direction to a vertical axis, and the principal direction of the first structure packing is parallel to the principal direction of the second structured packing.

2. A contactor as claimed in claim 1 , wherein said first structured packing is divided into a plurality of first structured packing portions, and wherein each of the plurality of first structured packing portions is surrounded by a portion of the second structured packing.

3. A contactor as claimed in claim 2 , wherein each of the plurality of first structured packing portions is substantially parallelepipedic, cylindrical, prismatic and/or has the shape of cylinder portions.

4. A contactor as claimed in claim 2 , wherein a volume of each portion of the second structured packing surrounding a portion of each of the plurality of first structured packing portions is smaller than a volume of the portion of each of the plurality of first structured packing portions it surrounds.

5. A contactor as claimed in claim 2 wherein the portions of the second structured packing surrounding the portions of the first structured packing have a substantially parallelepipedic shape, and form, in a horizontal plane, substantially perpendicular bands.

6. A contactor as claimed in claim 2 wherein the portions of the second structured packing surrounding the portions of the first structured packing have a substantially cylindrical shape, and form, in a horizontal plane, substantially concentric circles.

7. A contactor as claimed in claim 1 , wherein the second structured packing is provided at a periphery of the contactor.

8. A contactor as claimed in claim 1 , wherein the specific geometric surface area of the first structured packing ranges between 100 and 375 m 2 /m 3 .

9. A contactor as claimed in claim 1 , wherein the specific geometric surface area of the second structured packing ranges between 250 and 750 m 2 /m 3 .

10. A contactor as claimed in claim 1 , wherein the contactor comprises several packing layers for which the principal directions are substantially perpendicular to one another.

11. A column intended for heat and/or material exchange between a gas and a liquid, comprising at least one contactor as claimed in claim 1 .

12. A floating structure comprising at least one column intended for heat and/or material exchange between a gas and a liquid as claimed in claim 11 .

13. A process of using the column as claimed in claim 11 for a gas treatment, CO 2 capture, distillation or air conversion process by conducting heat and/or material exchange between a gas and a liquid in the at least one contactor of the column.

14. A contactor as claimed in claim 8 , wherein the specific geometric surface area of the second structured packing ranges between 250 and 750 m 2 /m 3 .

15. A contactor as claimed in claim 1 , wherein the specific geometric surface area of the first structured packing is substantially equal to 250 m 2 /m 3 .

16. A contactor as claimed in claim 15 , wherein the specific geometric surface area of the second structured packing is substantially equal to 500 m 2 /m 3 .

17. A contactor as claimed in claim 1 , wherein the specific geometric surface area of the second structured packing is substantially equal to 500 m 2 /m 3 .

18. A contactor as claimed in claim 8 , wherein the specific geometric surface area of the second structured packing is substantially equal to 500 m 2 /m 3 .
