Title: Device for separating non-ions from ions

Abstract

A device for separating non-ions from ions is disclosed. The device includes a plurality of electrodes positioned around a center axis of the device and having apertures therein through which the ions are transmitted. An inner diameter of the apertures varies in length. At least a portion of the center axis between the electrodes is non-linear.

  • A crown ether cesium ion extractant is disclosed as is its synthesis. The crown ether cesium ion extractant is useful for the selective purification of cesium ions from aqueous acidic media, and more particularly useful for the isolation of radioactive cesium-137 from nuclear waste streams. Processes for isolating cesium ions from aqueous acidic media using the crown ether cesium extractant are disclosed as are processes for recycling the crown ether cesium extractant and processes for recovering cesium from a crown ether cesium extractant solution. 4 figs.

  • A device for separating impurities from gases by means of a washing liquid is described. The device includes three (3) interconnected chambers: a suction chamber, a mixing chamber and a separating chamber, wherein the outer wall of the mixing chamber is the inner wall of the suction chamber and the inner wall of the mixing chamber is the outer wall of the separating chamber. In the upper portion of the mixing chamber there is an inlet which connects the suction and mixing chambers for conveying contaminated gases rising in the suction chamber downwardly into the mixing chamber. In the uppermore » portion of the mixing chamber below the outlet there is mounted a plurality of spray nozzles for downwardly spraying washing liquids which removes impurities in the contaminated gases as they flow downwardly through the mixing chamber. At the bottom of and directly open to the mixing and separating chambers is a liquid collection chamber for collecting used washing liquids and impurities from the gases. In the inner wall of the mixing chamber above the collection chamber is an outlet which conveys the washed gases from the mixing chamber upwardly into the separating chamber. The separator in the separating chamber removes remaining droplets of liquid from the washed gases before the washed gases pass into the surrounding atmosphere. Within an outer wall of the suction chamber there is an exhaust opening which is normally closed. When the device is operating properly the opening remains closed so that the contaminated gases will pass from the suction chamber to the mixing chamber. When there is a breakdown, however, the opening is opened so that the contaminating gases are exhausted from the device without passing therethrough.« less
  • A gas separation device includes an inner conduit, and a concentric outer conduit. An electrically conductive filter media, preferably a carbon fiber composite molecular sieve, is provided in the annular space between the inner conduit and the outer conduit. Gas flows through the inner conduit and the annular space between the inner conduit and the outer conduit, so as to contact the filter media. The filter media preferentially adsorbs at least one constituent of the gas stream. The filter media is regenerated by causing an electric current to flow through the filter media. The inner conduit and outer conduit aremore » preferably electrically conductive whereby the regeneration of the filter media can be electrically stimulated. The invention is particularly useful for the removal of CO.sub.2 from the exhaust gases of fossil-fueled power plants.« less
