A system for ammonia distillation may include a condenser to condense ammonia vapor into liquid anhydrous ammonia, a flush tank to receive a flushed portion of the liquid anhydrous ammonia, a collection tank to receive a collected portion of the liquid anhydrous ammonia, and a corrosion inhibitor dispenser to transfer a corrosion inhibitor to the collected portion of the liquid anhydrous ammonia to form corrosion-inhibiting liquid anhydrous ammonia.

Described are exhaust gas treatment systems for treatment of a gasoline engine exhaust gas stream. The exhaust gas treatment systems comprise an ammonia generating catalyst and an ammonia selective catalytic reduction (SCR) catalyst downstream of the ammonia generating catalyst. The ammonia generating catalyst comprises a NO.sub.x storage component, a refractory metal oxide support, a platinum component, and a palladium component. The ammonia generating catalyst is substantially free of ceria. The platinum and palladium components are present in a platinum to palladium ratio of greater than about 1 to 1.

Disclosed is a method of obtaining an inorganic nanostructured complex (CFI-1) by chemical synthesis and antitumor use. The main use is in treating cancer, both in animals and humans. The complex has singular antitumor activity, and can potentially be used as a substitute and/or act as an adjuvant for other commercial antineoplastic drugs.

Disclosed is a method for treating cancer in a subject by administering to the subject a compound selected from NH.sub.4MgPO.sub.4×6H.sub.2O, (NH.sub.4)2MgH.sub.2(PO.sub.4).sub.2×4H.sub.2O, (NH.sub.4)2Mg.sub.3(HPO.sub.4).sub.4×8H.sub.2O and NH.sub.4MgPO.sub.4×H.sub.2O associated or not to hydrolytic enzymes, which are known to have immunomodulatory activities.

Systems and methods for removing hydrogen sulfide from an ammonia stream in the NH3 purification and liquefaction stage of a conventional two-column sour water stripping system using an adsorbent bed.

A method for manufacturing an ammonia storage cartridge includes a step for supplying a material by ammonia absorption or adsorption by absorbent salts, a step for producing an intermediate element, including compacting the material to form the intermediate element, a step for stacking at least two intermediate elements in a shell of the cartridge, and a step for compressing the stack of intermediate elements in the shell.

The present disclosure relates to power plants. The teachings thereof may be embodied in processes for producing ammonia and energy, e.g., a method for producing ammonia and energy comprising: spraying or atomizing an electropositive metal; burning the metal with a reaction gas; mixing the reacted mixture with water; separating the mixture into (a) solid and liquid constituents and (b) gaseous constituents; at least partially converting energy of the solid and liquid constituents and of the gaseous constituents; and separating ammonia from the gaseous constituents. Mixing the reacted mixture may include spraying or atomizing the water or the aqueous solution or the suspension of the hydroxide of the electropositive metal into the reacted mixture.
