摘要: The disclosure relates to a liquefied ammonia-ammonium composition, also referenced herein as a eurefstic composition. The composition includes ammonia, an ammonium cation, and a halogenated anion, and the composition remains in liquid form at ambient temperatures and pressures. The composition can be formed by contacting gaseous ammonia with a solid halogenated ammonium salt, such as ammonium triflate or ammonium hexafluorophosphate, which absorbs the ammonia to form the liquid eurefstic composition. The eurefstic composition provides a convenient, safe, and ammonia-dense liquid that is easily transportable and safely storable until later use, for example to release and generate ammonia, to be electrolyzed to generate hydrogen gas, etc. The ammonia or hydrogen gas can then be used as a combustion fuel or other energy source.

摘要: A system for recovering ammonia from an ammonia-containing liquid, which system comprises a waste tank (10) for receiving ammonia-containing liquid entering the system; a filtration unit (14) comprising an ultrafiltration unit for receiving the ammonia-containing liquid from the waste tank (10) and filtering the ammonia-containing liquid to remove solids; an ammonia concentrating unit comprising a reverse osmosis unit (18) for receiving ammonia-containing liquid from the filtration unit (14) and concentrating the ammonia within the liquid; and an ammonia-recovery unit (100) for receiving concentrated ammonia-containing liquid from the ammonia concentrating unit (18) and recovering ammonia therefrom, wherein the ammonia-recovery unit (100) comprises a rectifier (102) for separating ammonia from the concentrated ammonia-containing liquid and recovering the ammonia as ammonia-containing gas; and wherein the system does not comprise an ammonia stripper.
