Abstract: A multiple stage apparatus and process using aerodynamic reactors and aero-coalescers in sequence for the selective capture and removal of purified carbon dioxide gas, the sequential capture and removal of mercury, metal and particulate aerosols by a recycling chemical generation-regeneration system using alkali metal chloride solution following multiple oxidations of mercury vapor, and nitric oxide in sequence, selective capture and removal of sulfur dioxide and nitrogen dioxide by two stage absorption by a recycling chemical generation-regeneration system using alkali metal hydroxide-carbonate-bicarbonate solution together with sequential oxidation to alkali metal sulfate and alkali metal nitrate compounds through evaporation and crystallization. Carbon dioxide capture and recovery is achieved in sequence by selective thermal decarbonation from an alkaline liquid followed by recovery as a purified gas stream.

Abstract: This patent describes technology for generating ammonia from urea. The method is based on the hydrolysis of an aqueous solution of urea and/or biuret by heating under pressure to form a mixture of ammonia, carbon dioxide and water. The gas mixtures produced are useful for supplying ammonia at controlled pressure and rate of flow for many industrial applications without the risks and hazards associated with the transportation and on-site storage of ammonia, thereby providing a significant safety advantage over present industrial practice.

Abstract: A cyclic process for removing lower valence nitrogen oxides from gaseous mixtures includes treating the mixtures in a first stage with an acidic aqueous media including a peroxygen oxidant to form nitric acid and higher valence nitrogen oides and to capture these oxides as alkali metal salts, especially nitrites and nitrates, in a carbonate/bicarbonate-containing product aqueous media in a second stage. Highly selective recovery of nitrates in high purity and yield may then follow, as by crystallization, with the carbonate and bicarbonate alkali metal salts strongly increasing the selectivity and yield of nitrates. The product nitrites are converted to nitrates by oxidation after lowering the product aqueous media pH to below about 9.Where the gas mixtures include both sulfur dioxide and lower valence nitrogen oxides, the processes for removing lower valence nitrogen oxides and sulfur dioxide may be combined into a single removal/recovery system, or may be effected in sequence.

Abstract: A cyclic process for removing lower valence nitrogen oxides from gaseous mixtures includes treating the mixtures with an aqueous media including alkali metal carbonate and alkali metal bicarbonate and a preoxygen oxidant to form higher valence nitrogen oxides and to capture these oxides as alkali metal salts, expecially nitrites and nitrates, in a carbonate/bicarbonate-containing product aqueous media. Highly selective recovery of nitrates in high purity and yield may then follow, as by crystallization, with the carbonate and bicarbonate alkali metal salts strongly increasing the selectivity and yield of nitrates. The product nitrites are converted to nitrates by oxidation after lowering the product aqueous media pH to below about 9.A cyclic process for removing sulfur oxides from gas mixtures includes treating these mixtures with aqueous media including alkali metal carbonate and alkali metal bicarbonate where the ratio of alkali metal to sulfur dioxide is not less than 2.

Abstract: A process for the removal and recovery of acidic gas(es) from a gaseous mixture comprising electrolysis of a chloride salt to produce an aqueous metal hydroxide solution, hydrogen and chlorine. The metal hydroxide solution is used to absorb acidic gas from the gaseous mixture and to form an aqueous metal salt. The hydrogen and chlorine are reacted to produce hydrochloric acid, which is used to decompose the aqueous metal salt to produce an aqueous chloride salt and acidic gas. Following separation, the aqueous chloride salt may be electrolyzed again.
