Abstract
Abstract ABSTRACT Apparatus for continuously contacting a gas with a liquid is provided, which apparatus comprises a centrifugal impeller, a generally cylindrical layer of high surface area permeable material disposed across the radial path of gas through the impeller, and means for feeding liquid to the radial inner face of the said layer. In the apparatus, particulate solid and/or sulphur dioxide, for example, may be removed from a gas.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
87 words
A method for preparing an apparatus for continuously contacting a gas with a liquid which apparatus comprises a centrifugal impeller which is in the form of a broadly annular arrangement of blades disposed radially or at an angle to the circumference of the annulus, a generally cylindrical layer of a high surface area permeable material disposed across the means for feeding the liquid to the radially inner face of the said layer which method comprises adding the said layer and the said means to an already-existing impeller.
Claim 2
Independent Claim
87 words
A method for preparing an apparatus for continuously contacting a gas with a liquid which apparatus comprises a centrifugal impeller which is in the form of a broadly annular arrangement of blades disposed radially or at an angle to the circumference of the annulus, a generally cylindrical layer of a high surface area permeable material disposed across the means for feeding the liquid to the radially inner face of the said layer which method comprises adding the said layer and the said means to an already-existing impeller.
Claim 3
Dependent Claim
31 words
Method as claimed in Claim 1 in which the layer of permeable material may be disposed in a cylindrical arrangement across the radially inner face of the annulus of impeller blades.
Claim 4
Dependent Claim
21 words
Method as claimed in Claim 1 in which the permeable material has a specific surface area of at least 1500 metres2/metres3.
Claim 5
Dependent Claim
25 words
Method as claimed in Claim 1 in which the permeable material comprises a knitted or woven fabric, a non-woven mat, a foam or a mesh.
Claim 6
Dependent Claim
59 words
Method as claimed in Claim 1 in which the liquid feed means comprises a plurality of perforated feed pipes, projecting into the interior of the impeller in a direction parallel to the axis of rotation of the impeller and each transmitting a plurality of jets or sprays of liquid towards the inner face of the layer of permeable material.
