Abstract
Abstract This invention provides an apparatus and method for contacting liquid with gas in a vessel in which an upstanding jetforming means directs jets of gas along a path having a horizontal component and through the liquid. The jet forming element may be an upright distributor having orifices spaced along its length from near the bottom of a tray to about the level of the liquid. The jets of gas generate a rising column of liquid and inject gas into the column so formed. Considerable velocity develops and the rapidly moving gas and liquid are impinged with turbulence against a plate and deflected downward. Currents of escaping vapor are driven against each other and against elements of the apparatus to coalesce and separate entrained droplets.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
25 words
The apparatus according to claim 1 wherein the jet forming means includes orifices spaced over the distance from said vessel bottom to said liquid level.
Claim 2
Dependent Claim
10 words
Apparatus according to claim 2 wherein the orifices are circular.
Claim 3
Dependent Claim
21 words
Apparatus according to claim 3 wherein the space between orifices is equal to more than about five times the orifice diameter.
Claim 4
Dependent Claim
119 words
Apparatus for contacting a body of liquid with a gas, a portion of which liquid is circulated as a rising column, comprising a tray having a side and bottom to contain the liquid to a predetermined level, means within said vessel to define at least a part of the path of said rising column, said means including an upright distributor located within said tray and having its upper end extending above the level of said liquid, said distributor having perforations for projecting jets of vapor outwardly into a substantial portion of the height of said column, a plate above said distributor to divert the rising column and baffle means to direct the vapor during its passage from the tray.
Claim 5
Dependent Claim
16 words
The apparatus of claim 5 wherein the distributor is a cylinder centrally located within the tray.
Claim 6
Dependent Claim
15 words
The apparatus of claim 5 wherein the perforations extend along the height of the distributor.
Claim 7
Dependent Claim
104 words
Apparatus for contacting a liquid with a vapor comprising a tray having a side and a sloping bottom to hold liquid to a predetermined level, an upright cylinder centrally located within said tray with its lower end spaced from the bottom and having its upper end extending above the liquid level, a distributor coaxially and concentrically within said cylinder and having perforations for projecting jets of vapor radially outward over substantially the entire depth of said liquid, a vapor supply pipe within said distributor, a liquid directing plate secured to the upper end of said distributor and having a diameter larger than said cylinder.
Claim 8
Dependent Claim
38 words
The apparatus of claim 8 including a deflector extending from said tray sides above said plate, a top supported from said side and defining a passage therebetween and a baffle depending from said top and over said deflector.
Claim 9
Dependent Claim
16 words
The apparatus of claim 8 wherein the perforations have a diameter of at least 0.03 inches.
Claim 10
Dependent Claim
34 words
The apparatus of claim 10 wherein the distance from the perforate wall of the distributor to the inside of the cylinder is from about 100 to about 200 times the diameter of a perforation.
Claim 11
Dependent Claim
17 words
The apparatus of claim 8 wherein a vapor supply pipe extends above the top of the cylinder.
Claim 12
Independent Claim
58 words
The method of contacting a liquid and a gas comprising the steps of providing a body of liquid, developing a rising column of liquid within said body, forming a gas into jets, directing the jets at about sonic velocity into said column over a substantial portion of its height and along a path transverse to its rising direction.
Claim 13
Dependent Claim
34 words
The process of claim 13 wherein the jets are circular and have a diameter of at least 0.03 inches and are spaced apart a distance equal to at least five times the jet diameter.
Claim 14
Dependent Claim
30 words
The method of claim 13 wherein a portion of the separation is achieved by the step of directing a stream of gas containing droplets of liquid against another such stream.
Claim 15
Dependent Claim
81 words
The process for treating liquid with a vapor comprising the steps of providing a body of liquid to be treated, circulating said liquid along a path adjacent jet forming means to establish a rising column at least partially within said body, providing a supply of vapor in said body, projecting jets of vapor outwardly from said supply and into said rising column over a major portion of its total height, separating the gas from the liquid and recovering the treated liquid.
Claim 16
Dependent Claim
35 words
The process of claim 1 wherein the rising column of liquid has an annular shape and surrounds the vapor supply and the jets are projected radially outward from said supply and through said rising column.
Claim 17
Dependent Claim
37 words
The process of claim 1 wherein separation of entrained liquid from the vapor includes the steps of directing the vapor and droplets radially inward and then radially outward to disengage droplets of the liquid from the vapor.
