Abstract
Abstract Liquid discharge members for liquid-vapor contacting trays having vertical side walls laterally confining a narrow oblong space, which accommodates the whole or a substantial part of a baffle fitting against the long side walls and running up and down, which creates compartments A that are open at the top and compartments B that are open at the bottom, lying next to one another in the sequence A-B-A-, of which the compartments A are provided with one or more discharge openings.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
77 words
A liquid discharge member for liquid-vapor contacting trays, comprising vertical side walls laterally confining a narrow oblong space, which accommodates at least part of a baffle fitting against the side walls and running up and down, which creates compartments A that are open at the top and compartments B that are open at the bottom, lying next to one another in the sequence A-B-A-, of which the compartments A are provided with one or more discharge openings.
Claim 2
Dependent Claim
77 words
A liquid discharge member for liquid-vapor contacting trays, comprising vertical side walls laterally confining a narrow oblong space, which accommodates at least part of a baffle fitting against the side walls and running up and down, which creates compartments A that are open at the top and compartments B that are open at the bottom, lying next to one another in the sequence A-B-A-, of which the compartments A are provided with one or more discharge openings.
Claim 3
Dependent Claim
17 words
A liquid discharge member according to claim 1, having a sharply folded baffle running up and down.
Claim 4
Dependent Claim
31 words
A liquid discharge member according to claim 2, wherein the vertical cross section of a compartment A has the shape of an isosceles trapezium with the short parallel at the bottom.
Claim 5
Dependent Claim
23 words
A liquid discharge member according to claim 3, wherein the height of the trapezium is equal to the height of the vertical walls.
Claim 6
Dependent Claim
40 words
A liquid discharge member according to claim 3, wherein the height of the trapezium is greater than the height of the vertical walls in such a fashion that the narrow side of the trapezium extends downwards beyond the vertical walls.
Claim 7
Dependent Claim
26 words
A liquid discharge member according to claim 3, wherein the narrow flat bottom side of the compartment A is provided with at least one discharge opening.
Claim 8
Dependent Claim
25 words
A liquid discharge member according to claim 3, wherein the trapeziform side-walls of the compartment A are, near the narrow side, provided with discharge openings.
Claim 9
Dependent Claim
31 words
A liquid discharge member according to claim 3, wherein the rectangular side-walls of the compartment A are, near the narrow side of the trapezium, provided with at least one discharge opening.
Claim 10
Dependent Claim
28 words
A liquid discharge member according to claim 2, wherein the vertical cross section of a compartment A has the shape of an isosceles triangle resting on its top.
Claim 11
Dependent Claim
31 words
A liquid discharge member according to claim 9, wherein discharge openings are presEnt in the triangular side-walls near the top and in the rectangular side-walls near the top of the triangle.
Claim 12
Dependent Claim
28 words
A liquid discharge member according to claim 1, wherein the vertical cross section of a compartment B has the shape of an isosceles triangle with the top uppermost.
Claim 13
Dependent Claim
18 words
A liquid discharge member according to claim 11, wherein the top angle of the isosceles triangle is 20*-100*.
Claim 14
Dependent Claim
41 words
A liquid discharge member according to claim 1, wherein the side-walls of the compartments B are provided with at least one aperture in that section which extends below the tray when the liquid discharge member has been mounted on that tray.
Claim 15
Dependent Claim
28 words
A liquid discharge member according to claim 1, wherein the narrow vertical side walls confining the rectangular space laterally form part of the baffle running up and down.
Claim 16
Dependent Claim
19 words
A liquid discharge member according to claim 1, wherein the terminal compartments perform the function of the compartments A.
Claim 17
Dependent Claim
29 words
A liquid discharge member according to claim 15, wherein the terminal compartments are, near the bottom, provided with one or more discharge openings in the terminal rectangular side face.
Claim 18
Dependent Claim
97 words
A tray provided with liquid discharge members which extend partly above and partly below the tray, each discharge member comprising a liquid discharge member for liquid-vapor contacting trays, comprising vertical side walls laterally confining a narrow oblong space, which accommodates at least part of a baffle fitting against the side walls and running up and down, which creates compartments A that are open at the top and compartments B that are open at the bottom, lying next to one another in the sequence A-B-A-, of which the compartments A are provided with one or more discharge openings.
Claim 19
Dependent Claim
97 words
A tray provided with liquid discharge members which extend partly above and partly below the tray, each discharge member comprising a liquid discharge member for liquid-vapor contacting trays, comprising vertical side walls laterally confining a narrow oblong space, which accommodates at least part of a baffle fitting against the side walls and running up and down, which creates compartments A that are open at the top and compartments B that are open at the bottom, lying next to one another in the sequence A-B-A-, of which the compartments A are provided with one or more discharge openings.
Claim 20
Dependent Claim
101 words
A column provided with trays each provided with liquid discharge members which extend partly above and partly below the tray, each discharge member comprising a liquid discharge member for liquid-vapor contacting trays, comprising vertical side walls laterally confining a narrow oblong space, which accommodates at least part of a baffle fitting against the side walls and running up and down, which creates compartments A that are open at the top and compartments B that are open at the bottom, lying next to one another in the sequence A-B-A-, of which the compartments A are provided with one or more discharge openings.
Claim 21
Dependent Claim
101 words
A column provided with trays each provided with liquid discharge members which extend partly above and partly below the tray, each discharge member comprising a liquid discharge member for liquid-vapor contacting trays, comprising vertical side walls laterally confining a narrow oblong space, which accommodates at least part of a baffle fitting against the side walls and running up and down, which creates compartments A that are open at the top and compartments B that are open at the bottom, lying next to one another in the sequence A-B-A-, of which the compartments A are provided with one or more discharge openings.
