  • Patent number: 10807895
    Abstract: The present invention relates to a process that uses one or more evaporators to treat produced water containing silica. To address silica scaling, a crystallizing reagent is mixed with the produced water upstream of the evaporator. The crystallizing reagent is designed to precipitate a silica adsorbing compound such as magnesium hydroxide. The feedwater with the adsorbed silica is directed to an evaporator that produces a distillate and a concentrate containing the adsorbed silica. At least a portion of the concentrate having the silica adsorbing compound is directed to a separator that separates the silica adsorbing compound from the concentrate and recycles it back to where it is mixed with the produced water.

  • Patent number: 10046268
    Abstract: Flue gas desulfurization processes and systems that utilize ammonia as a reactant, and in which any hydrogen sulfide and/or mercaptans within the ammonia are separated during the desulfurization process so as to prevent their release into the atmosphere. The process and system entail absorbing acidic gases from a flue gas with a scrubbing media containing ammonium sulfate to produce a stream of scrubbed flue gas, collecting the scrubbing media containing the absorbed acidic gases, injecting into the collected scrubbing media a source of ammonia that is laden with hydrogen sulfide and/or mercaptans so that the injected ammonia is absorbed into and reacted with the collected scrubbing media, stripping the hydrogen sulfide and/or mercaptans from the collected scrubbing media by causing the hydrogen sulfide and/or mercaptans to exit the collected scrubbing media as stripped gases, and collecting the stripped gases without allowing the stripped gases to enter the stream of scrubbed flue gas.

  • Patent number: 10036090
    Abstract: A trap mechanism is provided in the middle of an exhaust passage through which an exhaust gas, which is exhausted from a film formation device body that forms a thin film on the surface of a workpiece (W), flows, and recovers a gas to be collected that is contained in the exhaust gas by cooling and liquefying the gas to be collected. The trap mechanism includes: a housing having a gas inlet and a gas outlet; a partitioning member that partitions the inside of the housing into retention spaces; communication paths that communicate the retention spaces with one another; and cooling jackets that cool the communication paths to cool the exhaust gas. With this structure, the exhaust gas is adiabatically expanded while being cooled, and the gas to be collected is efficiently cooled and liquefied.
