Structured WV packing elements

Claim 2

An improved packing element for placing within an exchange column of the type consisting of a plurality of parallel, adjacent corrugated plates, the corrugations between adjacent plates lying in an abutting, non-parallel relation, wherein the improvement comprises: a plurality of first notches formed on multiple surfaces on each of said corrugated plates, said multiple surfaces formed on said corrugated plates between a plurality of ridges and a plurality of adjacent troughs thereof; and a plurality of second notches formed on said multiple surfaces and cooperating with said plurality of first notches to form a fluid flow stream path within a plurality of the individual corrugated plates, said first notches comprise in combination, W-shaped openings in said corrugated plate and a pair of drip points adjacent to and in fluid communication with said W-shaped openings, and said second notches comprise in combination V-shaped openings in said corrugated plate and a fluid directional member adjacent to and in fluid communication therewith, whereby said first and said second notches effect an enhanced uniform distribution of a downwardly flowing fluid through the packing element.

Claim 3

An improved packing element as described in claim 1, wherein said first notches and said second notches each form separate linear arrays on said multiple surfaces, said first notch linear array upstream with respect to said second notch linear array on each of said multiple surfaces of the corrugated plate.

Claim 4

A packing element for use in an exchange column comprising: a plurality of corrugated plates placed adjacent to and parallel with one another, the corrugations of each of said plates forming a non-parallel relationship with the corrugations of an adjacent plate and with a vertical axis of the exchange columns each of said plates having a plurality of first W-shaped, notches and a plurality of second, V-shaped notches formed therein, with a first linear array of said first, W-shaped notches and a second linear array of said second, V-shaped notches provided on a surface of the corrugated plate between a ridge and a trough thereof, said first and second linear arrays comprising a sequential pair of linear arrays on each of said surfaces, with at least one sequential pair of linear arrays located on a plurality of the surfaces of the corrugated plate lying between the ridges and the troughs thereof. said W-shaped and said V-shaped notches sized and located on said plate in a manner permitting fluid communication between adjacent corrugated surfaces of said plate when placed within said exchange column, whereby said first and second notches effect enhanced mass transfer and heat exchange rates within the packing elements.

Claim 5

A packing element for use in an exchange column comprising: a plurality of corrugated plates placed adjacent to and parallel with one another, the corrugations of each of said plates forming a non-parallel relationship with the corrugations of an adjacent plate and with a vertical axis of the exchange columns each of said plates having a plurality of first W-shaped, notches and a plurality of second, V-shaped notches formed therein, with a first linear array of said first, W-shaped notches and a second linear array of said second, V-shaped notches provided on a surface of the corrugated plate between a ridge and a trough thereof, said first and second linear arrays comprising a sequential pair of linear arrays on each of said surfaces, with at least one sequential pair of linear arrays located on a plurality of the surfaces of the corrugated plate lying between the ridges and the troughs thereof. said W-shaped and said V-shaped notches sized and located on said plate in a manner permitting fluid communication between adjacent corrugated surfaces of said plate when placed within said exchange column, whereby said first and second notches effect enhanced mass transfer and heat exchange rates within the packing elements.

Claim 6

A packing element for use in an exchange column as described in claim 1, wherein said W-shaped notches each comprise a W-shaped opening formed in said corrugated plate, having a pair of drip points formed adjacent and in fluid communication with said W-shaped opening, whereby a plurality of drip points are formed on the corrugated plate, receiving that portion of a fluid flow stream within the packing element flowing through the W-shaped opening.

Claim 7

A packing element for use in an exchange column as described in claim 4, wherein said V-shaped notches each comprise a V-shaped opening formed in said corrugated plate having at least one fluid directional member adjacent to and in fluid communication with said V-shaped opening, whereby a portion of the fluid flow stream within the packing element is received by the V-shaped opening and is directed by the fluid directional member.

Claim 8

A packing element for use in an exchange column as described in claim 5, wherein said W-shaped opening is at least 2 millimeters in width.

Claim 9

A packing element for use in an exchange column comprising: a plurality of corrugated plates placed adjacent to and parallel with one another, the corrugations of each of said plates forming a non-parallel relationship with the corrugations of an adjacent plate and with a vertical axis of the exchange column, each of said plates having a plurality of first notches and a plurality of second notches formed therein, said first notches each comprise a W-shaped opening formed in said corrugated plate, having a pair of drip points formed adjacent and in fluid communication with said W-shaped opening, and said second notches each comprise a V-shaped opening formed in said corrugated plate having at least one fluid directional member adjacent to and in fluid communication with said V-shaped opening, with said plurality of W-shaped openings and said plurality of V-shaped openings formed on a surface of said corrugated plate in an alternating manner, and with respect to a fluid flowing through said packing element, said W-shaped openings are located upstream of said V-shaped openings on each surface formed on said corrugated plate between a ridge and a trough thereof, whereby a portion of the fluid passes first through a W-shaped opening, with the V-shaped opening on said same surface receiving the remaining fluid, in addition to receiving that amount of fluid dripping onto said same surface from a W-shaped opening formed on said corrugated plate in a surface overlying said same surface.

Claim 10

A packing element for use in an exchange column comprising: a plurality of corrugated plates placed adjacent to and parallel with one another, the corrugations of each of said plates forming a non-parallel relationship with the corrugations of an adjacent plate and with a vertical axis of the exchange column, each of said plates having a plurality of first notches and a plurality of second notches formed therein, said first notches each comprise a W-shaped opening formed in said corrugated plate, having a pair of drip points formed adjacent and in fluid communication with said W-shaped opening, and said second notches each comprise a V-shaped opening formed in said corrugated plate having at least one fluid directional member adjacent to and in fluid communication with said V-shaped opening, with said plurality of W-shaped openings and said plurality of V-shaped openings formed on a surface of said corrugated plate in an alternating manner, and with respect to a fluid flowing through said packing element, said W-shaped openings are located upstream of said V-shaped openings on each surface formed on said corrugated plate between a ridge and a trough thereof, whereby a portion of the fluid passes first through a W-shaped opening, with the V-shaped opening on said same surface receiving the remaining fluid, in addition to receiving that amount of fluid dripping onto said same surface from a W-shaped opening formed on said corrugated plate in a surface overlying said same surface.
