            <description><![CDATA[An arrangement establishes a focused clean air zone column. The arrangement comprises an ultra-high grade filter having an air intake and an air flow generator that forces air from the intake through the filter. The air flow generator is operable to force air from the filter at a velocity between 70 feet per minute to 200 feet per minute to form a focused clean air zone column of air extending from the filter.]]></description>

            <description><![CDATA[The invention refers to a plant and a method for separating oil in form of particles and/or mist from a fossil gas mixture for obtaining a separated gas. The plant comprises a centrifugal separator with a stationary casing defining a separation space. The casing permits a pressure of at least 10 bars in the separation space. The centrifugal separator comprises an inlet for the gas mixture, a gas outlet for the separated gas and an oil outlet for discharging separated oil. A separating member for separating the gas mixture comprises a plurality of separating discs and is provided in the separation space. A drive motor is connected to the separating member via a spindle and rotate the separating member about an axis (x) of rotation.]]></description>

            <link>http://www.freepatentsonline.com/y2012/0031269.html</link>
            <description><![CDATA[A method and a device for purifying a carbon-dioxide-containing gas stream are described, in which the gas stream is first subjected in a lower section (3) of an absorption column (1) to a prescrubbing for conditioning the gas stream and subsequently in an upper section (8) of the absorption column (1) the carbon dioxide is scrubbed out from the gas stream at least in part with a scrubbing liquid. For improving the construction of the absorption column it is proposed that the entire scrubbing liquid loaded with the carbon dioxide which is scrubbed out is taken off from the absorption column (1) and fed to a receiver tank (11) arranged outside the absorption column (1) and subsequently applied to a scrubbing liquid pump (12) which pumps the scrubbing liquid to a scrubbing medium regeneration stage.]]></description>
