摘要： A process for continuously separating acids from a mixture of acids and their corresponding salts employing the concept of acid retardation is disclosed. The process is carried out by feeding the mixture to an Advanced Separation Device filled with a resin which preferentially adsorbs the acid over the corresponding salt. By virtue of the preferential adsorption of the acid by the resin, the addition of an eluant such as water causes the salt to elute first and the acid second. The Advanced Separation Device enables the process to be carried out continuously and is amenable to the low relative treatment ratios necessary for exploitation of the acid retardation concept.

摘要： A process for the continuous removal of ammonia from wastewater which converts the otherwise undesirable ammonia to a commercially useful end product such as ammonium phosphate. The process is carried out in an Advanced Separation Device which comprises a plurality of chambers (14) moving in a circular path in periodic fluid communication with a plurality of fixed feed ports (12) and discharge ports (16). The chambers (14) are filled with a zeolite adsorbent which effectively adsorbs the ammonium ions contained in the wastewater at low pH levels but which, when contacted with an alkaline regeneration solution, releases the previously adsorbed ammonia in the form of ammonia gas. Acidic materials may be added to the wastewater in an intra-stage fashion i.e. during the adsorption step, so as to optimize process efficiency. Similarly, intra-stage addition of alkaline materials during the regeneration step results in increased process efficiency. The process may be practided with both industrial and municipal wastewaters.

摘要： A process for the production of dialkali metal phosphates by ion exchange is disclosed. The process is carried out by first ammoniating a water-soluble phosphate source such as phosphoric acid or monocalcium phosphate. The resulting ammoniated phosphate solution is then contacted with a weak cation exchange resin in the alkali metal form to produce the dialkali metal phosphate as well as an ammonium-loaded weak cation exchange resin. The cation exchange resin is regenerated by contacting it with an alkali metal salt solution which effects an exchange of alkali metal for ammonium to produce a regenerated weak cation exchange resin in the alkali metal form as well as a water-soluble ammonium salt corresponding to the initial alkali metal salt. The process may be carried out in conventional fixed or pulsed bed ion exchange systems although it is most advantageously carried out in an Advanced Separation Device which is a multi-chambered device which enables the process to be carried out both continuously and with a greater degree of efficiency than is possible using conventional ion exchange systems.

摘要： The artificial moving bed of this invention includes a fluid distribution apparatus consisting of an upper fluid distributor and a lower fluid distributor, and a plurality of processing chambers held and fixed between the upper and lower fluid distributors. Each fluid distributor has a rotary valve held in a slidable condition between a fixed supply valve and a pipe fixing plate. These fluid distributors are formed with fluid passages therein. The processing chambers are divided into several groups, each assigned a specific process. Using this artificial moving bed, the processing chambers are operated simultaneously and when the process is finished in each group of processing chambers, the fluid distribution apparatus is rotated clockwise when viewed from above so that each group of chambers proceeds to the next process, thus allowing continuous adsorption operation.

摘要： A process for enhancing the concentration of one component contained in a multi-component gas, which is particularly well-suited for enriching the oxygen content of air, is carried out by a series of adsorption and desorption stages using an Advanced Separation Device comprised of a plurality of adsorbent-filled chambers (14) moving about a circular path in periodic fluid communication with a plurality of fixed feed ports (12) and discharge ports (16). The oxygen content of air is loaded onto the adsorbent which is then stripped by a second stream of air. This oxygen-enriched stream of air may then be divided so that the oxygen content of one stream may be adsorbed for subsequent removal by the other stream to produce a doubly- enriched stream.

摘要： A process for removing sulfur dioxide from flue gas is disclosed. After passing through a precipitator to remove particulate material, the flue gas is conducted continuously through a fixed bed solid-gas contacting device containing activated carbon or natural zeolite. The bed is regenerated continuously, thereby producing sulfuric acid which may be mixed with ground phosphate rock to produce normal superphosphate, or other by-products.
