摘要： Provided is a method for high concentration cation exchange metathesis of divalent ions such as calcium with univalent ions such as sodium or potassium. Due to the difference between ionic valences between the exchanged ions, the provided process behavior is strongly dependent upon the selection of resin properties and to total solution normality. A combination of resin properties and solution normality is provided to achieve the cation exchange.

摘要： A method is provided for producing thiosulfate from oxidation of reduced sulfur species without producing elemental sulfur and without converting more than 9% of the sulfur species to sulfate ion. The method consists essentially of oxidizing a thiosulfate solution with an oxidizing agent to produce a partially oxidized solution, adjusting the pH of the partially oxidized stream to between 5 and 8; and contacting the partially-oxidized solution with a stream containing a reduced sulfur species so that the reduced species is oxidized and the partially-oxidized stream reduced.

摘要： A process for treating a gas comprising hydrogen sulfide and carbon dioxide (1) by contacting the gas with a scrub solution comprising ammonium sulfite and ammonium bisulfite (2) in a first contact zone (3) to produce ammonium thiosulfate. The scrub solution can be formed in a second contact zone (6) by contacting ammonia (8) and sulfur dioxide (7) with an aqueous solution. The oxidation potential of the first contact zone effluent liquid can be controlled by modulating the amount of sulfur dioxide supplied to the second contact zone. Alternatively, the sulfite concentration of the first contact zone effluent can be measured with an infra-red analyzer and the amount of sulfur dioxide supplied to the second contact zone is modulated in response. Additionally, the amount of ammonia supplied to the second contact zone can be modulated in response to the pH in the second contact zone.

Additionaily, the amount of ammonia supplied to the second contact zone can be modulated in response to the pH in the second contact zone. The process can further comprise a solvent scrubber to remove carbon dioxide from the first contact zone overhead gas. A third contact zone can be included in the process to separate the hydrogen sulfite from the carbon dioxide in the solvent regenerator overhead gas.

摘要： Carbonaceous materials are thermally upgraded in a pressurized steam environment to remove moisture and other byproducts. A variety of water/solid separation devices may be employed in a process vessel to maximize moisture removal from the upgraded charge. Heating media inlet nozzles and process chamber vents are strategically positioned at the process vessel wall to minimize short circuiting of heating media to vessel outlet vents and to continuously separate hot water removed from the charge and condensed steam, such that the upgraded material removed from the process vessel is not discharged with accompanying free moisture. After upgrading, the charge may be rehydrated to improve its stability during shipping and storage.
