            <link>http://www.freepatentsonline.com/y2013/0146538.html</link>
            <description><![CDATA[The present invention is for high permeance and high selectivity blend polymeric membranes comprising poly(ethylene glycol) (PEG) and a highly permeable polymer selected from the group consisting of polymers of intrinsic microporosity (PIMs), tetrazole-functionalized polymers of intrinsic microporosity (TZPIMs), or mixtures thereof. The present invention also involves the use of such membranes for separations of liquids and gases.]]></description>

            <link>http://www.freepatentsonline.com/y2013/0145934.html</link>
            <description><![CDATA[A regenerator that can handle rich loaded chemical solvent containing precipitated absorption reaction products is disclosed. The invention is particularly suitable for separating CO2 from large gas streams that are typical of power plant processes. The internally circulating liquid stream in the regenerator (ICLS regenerator) rapidly heats-up the in-coming rich solvent stream in a downcomer standpipe as well as decreases the overall concentration of CO2 in the mixed stream. Both these actions lead to dissolution of precipitates. Any remaining precipitate further dissolves as heat is transferred to the mixed solution with an inverted bayonet tube heat exchanger in the riser portion of the regenerator. The evolving CO2 bubbles in the riser portion of the regenerator lead to substantial gas hold-up and the large density difference between the solutions in the downcomer standpipe and riser portions promotes internal circulation of the liquid stream in the regenerator. As minor amounts of solvent components present in the exit gas stream are condensed and returned back to the regenerator, pure CO2 gas stream exits the disclosed regenerator and condenser system.]]></description>

            <link>http://www.freepatentsonline.com/y2013/0145932.html</link>
            <description><![CDATA[An apparatus for reducing soot particles in exhaust gas, particularly of an internal combustion engine, includes first and second at least partially electrically conductive structures with an intermediate space therebetween, a high voltage source forming a potential between the first and second structures and at least one at least partially electrically conductive intermediate structure in the intermediate space receiving an intermediate potential. A method for treating the exhaust gas includes conducting exhaust gas from the first to the second structure and applying a high voltage at least temporarily between the first and second structures. At least part of the soot particles in the exhaust gas is ionized or agglomerated and deposited on the second structure. A high voltage between potentials of the first and second structures is applied at least temporarily to the intermediate structure. An electric field is influenced favorably and disruptions from undesirable voltage flashovers are reduced.]]></description>

            <description><![CDATA[The present invention discloses a new type of high selectivity UV-cross-linked tetrazole group functionalized polymer nanosieve (TZPIM) membranes, their preparation, as well as their use for gas and liquid separations. The UV-cross-linked TZPIM membrane showed more than 50% improvement in CO2/CH4 selectivity and more than 30% improvement in CO2/N2 selectivity compared to the uncross-linked TZPIM membrane for CO2/CH4 and CO2/N2 separations, respectively.]]></description>
