摘要： A method of wet-scrubbing a waste gas containing sulfur dioxide (SO2) to produce potassium thiosulfate. The wet-scrubbing facility includes multiple horizontally disposed stages where a preceding stage passes partially-scrubbed waste gas to a succeeding stage. Each stage has a scrubber mechanism to scrub waste gas with circulating fluid that progressively reduces SO2 in the waste gas before atmospheric discharge. The scrubber mechanism may optionally include a packing material to facilitate absorption of SO2 by the fluid, a sump disposed at the output of the stage to receive fluid as it drains from the packing, and a circulation pump to circulate fluid from the sump to its packing and to cascade at least a portion of the fluid back to a preceding stage. A portion of the fluid is extracted and reacted in a reaction vessel with a cation to produce potassium thiosulfate.

摘要： A method and a facility for wet-scrubbing sulfur dioxide to produce, for example, potassium thiosulfate or ammonium thiosulfate. The facility includes a multi-section vessel having multiple horizontally disposed stages where a preceding stage passes partially-scrubbed waste gas to a succeeding stage. Each stage has a scrubber mechanism to scrub waste gas with circulating fluid that successively reduces waste gas concentration before atmospheric discharge. The scrubber mechanism may include a packing to facilitate absorption of waste gas by the fluid, a sump disposed at the output of the stage to receive fluid as it drains from the packing, and a circulation pump to circulate fluid from the sump to its packing and to cascade at least a portion of the fluid back to a preceding stage. A portion of the fluid is extracted from the facility and reacted in a reaction vessel with a cation to produce ammonium thiosulfate or potassium thiosulfate.

摘要： This invention relates to production of an aqueous solution containing ammonium thiosulfate from a feed gas containing hydrogen sulfide (H2S) and ammonia (NH3). Sufficient separation of feed gas H2S from NH3 is achieved by controlling individual NH3 and H2S absorption mass-transfer rates in a single co-current stage, whereby a first gas contacts a first liquid containing ammonium bisulfite (ABS). Substantially more NH3 is absorbed than H2S, converting ABS to diammonium sulfite (DAS). A portion of DAS reacts with a sufficiently small portion of H2S to produce ATS and leaves as a second liquid stream. A larger portion of H2S leaves as a second gas stream. The second gas stream is oxidized to sulfur dioxide (SO2) comprising a third gas stream. The third gas stream contacts the second aqueous stream in a second contact stage whereby DAS in the second liquid stream is converted to ABS and returned to the first contacting zone.

摘要： A method for removing hydrogen sulfide from a biogas, wherein the hydrogen sulfide is absorbed in an aqueous liquid to produce a cleaned gas having a reduced amount of hydrogen sulfide relative to the biogas. The aqueous liquid is subsequently treated by contacting with a sulfur dye or sulfurized vat dye in the presence of an oxidizer such as oxygen gas, to convert the sulfides in the aqueous liquid to a non-toxic, water-soluble, product.

摘要： The invention relates to a process for preparing potassium thiosulfate, potassium sulfite or potassium bisulfite comprising the following steps: Step (1a): providing a potassium hydroxide or potassium carbonate solution for neutralizing acid forming components such as dissolving SO2 or H2S; Step (1b): providing an SO2 contacting solution, containing at least some potassium sulfite or potassium bisulfite or potassium thiosulfate; Step (2): providing SO2 gas; Step (3): reacting these to absorb the SO2 gas and to form an intermediate reaction mixture comprising potassium sulfite, or potassium bisulfite or a mixture thereof, and optionally recovering the potassium sulfite, or potassium bisulfite or a mixture thereof, and/or optionally using steps 4 and 5; Step (4): adding sulfur or sulfide containing compound containing sulfur having the oxidation state of 0, −2 or of between 0 and −2 to the reaction mixture and optionally potassium hydroxide or potassium carbonate, and reacting the mixture under suitable conditions to form potassium thiosulfate; and Step (5): recovering the potassium thiosulfate, and optionally concentrating the potassium thiosulfate.

摘要： A semiconductor device can be prepared using a precursor dielectric composition that comprises: (1) a photochemically or thermally crosslinked product of a photocurable or thermally curable thiosulfate-containing polymer that has a Tg of at least 50° C. and that comprises: an organic polymer backbone comprising (a) recurring units comprising pendant thiosulfate groups; and further comprises charge balancing cations, and (2) optionally, an electron-accepting photo sensitizer component. The electronic device can be prepared by independently applying the precursor dielectric composition and an organic semiconductor composition to a substrate to form an applied precursor dielectric composition and an applied organic semiconductor composition, respectively, and subjecting the applied precursor dielectric composition to curing conditions to form a gate dielectric layer that is in physical contact with the applied organic semiconductor composition.

摘要： A process and system for hydrogen sulfide capture from gas streams employing an absorber vessel in which the gas stream containing hydrogen sulfide is contacted with an absorbent solution to remove the hydrogen sulfide from the gas stream. The process and system may further employ an oxidation vessel in which sulfides and/or bisulfides in the absorbent solution are oxidized to produce a thiosulfate and/or sulfate, yielding a solution that can be used as fertilizer or other applications.
