摘要： A liquid concentrator system includes a concentrator section having a gas inlet, a gas outlet, and a mixing corridor disposed between the gas inlet and the gas outlet. A liquid inlet is disposed in the mixing corridor between the gas inlet and a narrowed portion. A demister is disposed downstream of the concentrator section. The demister includes a liquid collector to remove liquid from gas flowing through the demister, and a reservoir that collects the removed liquid. A re-circulating circuit is disposed between reservoir and the mixing corridor to transport liquid within the reservoir to the mixing corridor, and a secondary re-circulating circuit includes a settling tank to separate saturated liquid and suspended solids. A custom brine mixing device is operatively coupled to the settling tank.

摘要： A reclaiming method is disclosed including conducting evaporation by introducing a part of the absorbent to recover CO2 or H2S in a gas in a closed system recovery unit and separating a degraded substance contained in the absorbent from the absorbent to be introduced into an evaporator and obtain recovery steam containing an absorbent and CO2 or H2S by a heating section that is provided on a circulation line that circulates in the evaporator; and removing ionic degraded substance by cooling the concentrate obtained in the evaporation and removing an ionic degraded substance in the concentrate after the cooling, wherein a purified concentrate from which the ionic degraded substance has been removed is reused as a purified absorbent.

摘要： A method for removing selenium according to the present invention comprises: a valence change step of adding an oxidant to a wastewater from a facility that gasifies a fuel containing selenium in a reducing atmosphere, and oxidizing the selenium to change the valence of the selenium, and a solid-liquid separation step of adding a flocculant to the wastewater, forming a floc containing the selenium for which the valence has been changed in the valence change step, and subjecting the floc to solid-liquid separation.

摘要： A treatment process for remediating a contaminated liquid containing more than 5 ppm hydrogen sulfide, includes steps of: preparing a treatment solution containing an aqueous solution containing ≥1 hydroxide compound, in which a collective concentration of the ≥1 hydroxide compound in the aqueous solution is in a range of 35-55 weight percent and the aqueous solution constitutes at least 95% of the treatment solution; adding to the liquid an amount of an treatment solution sufficient to reduce a concentration of hydrogen sulfide in the contaminated liquid to ≤5 ppm based on stoichiometry of reactions between the ≥1 hydroxide compound and the hydrogen sulfide in the liquid; and dispersing the treatment solution in the liquid and allowing the treatment solution to react with the contaminated liquid for a period of time until a concentration of hydrogen sulfide in the liquid is reduced to ≤5 ppm.

摘要： The present invention provides for the use of a metal-organic framework (MOF) in removing particular chemical species or compounds, in particular oxy-anions, from a liquid or liquid stream. In some embodiments, the MOF is a Zr-based MOF, such as NU-1000, and the oxy-anions that are removed include, include, for example, oxy-anions of selenium, including selenite (SeO32−) and selenate (SeO42−); oxy-anions of antimony, including oxy-anions in either the Sb[III] (antimonite) or the Sb[V] (antimonate) redox state; and oxy-anions of lead, including oxy-anions in either the Pb[II] or the Pb[IV] redox state, such as Pb(OH)62−, Pb(OH)64−, PbO32−, and PbO22−. The Zr-based MOF, including NU-1000 can be used to remove these oxy-anions from various liquid streams in industrial processes such as a nuclear and fossil fuel power plants, including the latter's flue gas desulfurization system.

摘要： A portable water recycling and treatment system and process for used and produced flowback frac water pumps the water from a collection tank through a series of dedicated hydration, retention and filtering tanks and vessels that provide treatment for the removal of chemicals, sediments and other containments. The system, which is enclosed, can be readily assembled on-site by interconnecting the dedicated tanks, vessels and pumps. The tanks and vessels may be situated in a plurality of trailers that are transported separately to the site.

摘要： A process is presented where a feed stream containing a hydrogen sulfide and another feed component is introduced into an absorber that the feed stream flows upward from the bottom of the absorber and contacts a liquid treatment solution, where the liquid treatment solution contains a sulfur dye catalyst. The hydrogen sulfide is absorbed into the liquid treatment solution and converted into sulfide ions. The other feed component is removed from the absorber vessel substantially free of the hydrogen sulfide and a spent treatment solution is also removed from the absorber vessel and fed to an oxidation vessel where it is contacted with an oxygen containing gas causing the sulfide ions to oxidize to thiosulfate and converting the spent sulfur dye catalyst to regenerated sulfur dye catalyst. The thiosulfate is recovered, and the regenerated sulfur dye catalyst can be recycled as part of the liquid treatment solution.

摘要： The invention relates to methods and apparatuses for treating a condensate stream from a condenser that contains odorous compounds, such as various condensate streams produced in a rendering process. In one embodiment, the condensate stream is treated by adding an oxidizer to the liquid condensate stream to oxidize odor-causing compounds in the stream prior to being treated in a waste water pre-treatment system. In this manner, the odor resulting from these compounds can be reduced or eliminated.
