  • Patent number: 11685676
    Abstract: A water treatment system that removes calcium and magnesium using coagulants and pH controls, aqueous phase organic materials from water using a biological removal system that includes microorganisms and a physical separation system that includes sparging equipment for sparging the water to remove non-aqueous phase liquid organic materials, volatile phase organic materials. An apparatus, system and method for pretreating oilfield produced water to completely remove or significantly reduce concentrations of substances that are known to interfere with downstream recovery of metals including lithium. This technology facilitates a more efficient and cost-effective extraction method from alternate sources to meet the increasing global demand.

  • Patent number: 5714127
    Abstract: A system for the multiple, simultaneous synthesis of compounds preferably uses a reaction apparatus comprising a reservoir rack having a plurality of reaction wells, a plurality of reaction tubes, usually gas dispersion tubes, having filters on their lower ends, a holder block, having a plurality of apertures, and a manifold, which has ports to allow introduction/maintenance of a controlled environment. The manifold top wall has a plurality of apertures in axial alignment with the reaction tubes and a gasket which allows penetration by a needle in order to dispense and aspirate materials from the reaction tubes. Sealing members, such as gaskets, are placed between the holder block, manifold and reservoir rack and the components are releasably fastened together. A robotic sample processor is used to automate the synthesis process using the reaction apparatus.

  • Patent number: 5702672
    Abstract: An apparatus for multiple, simultaneous synthesis of compounds which consists of: a reservoir block having a plurality of wells; a plurality of reaction tubes, usually gas dispersion tubes, having filters on their lower ends; a holder block, having a plurality of apertures; and a manifold, which may have ports to allow introduction/maintenance of a controlled environment. The manifold top wall has apertures and a detachable plate with identical apertures. The apparatus is constructed from materials which will accommodate heating, cooling, agitation, or corrosive reagents. Gaskets are placed between the components. Rods or clamps are provided for fastening the components together. Apparatus operation involves placing the filters on the lower ends of the reaction tubes in the reservoir block wells, and the upper ends passing through the holder block apertures and into the manifold.
