Packing having catalytic or absorbent agents

Claim 2

A packing for placement in an elongated container having an inlet and an outlet for a fluid medium flowing in an axial direction through the container, the packing comprising first and second adjacent layers which are parallel to the flow direction of the fluid medium and extend over at least a portion of the length of the container, each layer including a plurality of parallel, spaced-apart, tubular, elongated packing parts which are angularly inclined relative to the flow direction, the packing parts of the first layer being angularly inclined relative to the packing parts of the second layer to define first and second flow channels in the first and second layers which are angularly inclined with respect to each other and to the flow direction and which are fluidly interconnected, each packing part comprising a fluid medium permeable fabric having closed sides and ends and holding therein a catalytic or adsorbent material for contacting the fluid medium, and having a support structure which orients and supports the packing parts of the first and second layers in their respective positions and angular orientations.

Claim 3

A packing according to claim 1 wherein the catalyst or adsorption material comprises a bulky granulate.

Claim 4

A packing according to claim 1 wherein the packing parts are made from one of wire braid and knitted wire cloth.

Claim 5

A packing according to claim 1 wherein the support structure comprises a three-dimensional lattice.

Claim 6

A packing according to claim 1 wherein the support structure comprises a static mixer structure for the fluid medium.

Claim 7

A packing according to claim 4 wherein the support structure comprises a zig-zag folded sheet which includes spaced-apart openings.

Claim 8

A packing according to claim 1 wherein the packing parts comprise means for suspending them in the support structure.

Claim 9

A packing according to claim 1 wherein the support structure comprises ducts, and wherein at least two packing parts are disposed one behind the other in at least some individual ducts.

Claim 10

A packing according to claim 1 wherein the catalyst material is a liquid, and including a membrane placed against a side of each layer facing the other layer, the membrane being impermeable by the liquid and permeable by the fluid medium, each membrane being sealed to the other and the liquid catalyst being disposed between the membranes, the layers forming a fluid permeable support structure for the membranes.

Claim 11

A column for treating a fluid medium comprising a tubular, elongated container having an inlet and an outlet for a fluid medium flowing in an axial direction through the container, at least one packing disposed in the container including first and second adjacent layers which are parallel to the flow direction of the fluid medium and extend over a portion of the length of the container, each layer including a plurality of parallel, spaced-apart, tubular, elongated packing parts which are angularly inclined relative to the flow direction, the packing parts of the first layer being angularly inclined relative to the packing parts of the second layer to define first and second flow channels in the first and second layers which are angularly inclined with respect to each other and to the flow direction, the flow channels of each layer being fluidly separated from each other by a packing part and having means for fluidly interconnecting selected flow channels of the first and second layers, each packing part comprising a fluid medium permeable fabric having closed sides and closed ends and holding therein a catalytic or adsorbent material for contacting the fluid medium, and having a support structure permitting fluid flow between the selected flow channels in the first and second layers and which orients and carries the packing parts of the first and second layers in their respective positions and angular orientations.

Claim 12

A column for treating a fluid medium comprising a tubular, elongated container having an inlet and an outlet for a fluid medium flowing in an axial direction through the container, at least one packing disposed in the container including first and second adjacent layers which are parallel to the flow direction of the fluid medium and extend over a portion of the length of the container, each layer including a plurality of parallel, spaced-apart, tubular, elongated packing parts which are angularly inclined relative to the flow direction, the packing parts of the first layer being angularly inclined relative to the packing parts of the second layer to define first and second flow channels in the first and second layers which are angularly inclined with respect to each other and to the flow direction, the flow channels of each layer being fluidly separated from each other by a packing part and having means for fluidly interconnecting selected flow channels of the first and second layers, each packing part comprising a fluid medium permeable fabric having closed sides and closed ends and holding therein a catalytic or adsorbent material for contacting the fluid medium, and having a support structure permitting fluid flow between the selected flow channels in the first and second layers and which orients and carries the packing parts of the first and second layers in their respective positions and angular orientations.

Claim 13

A column according to claim 10 including a plurality of packings serially arranged in the housing.
