Zusammenfassung:	Processes for recovering ammonia from an ammonium sulfate stream include reacting the ammonia sulfate stream with a lime slurry to form a slurry comprising calcium sulfate and ammonia; providing the slurry comprising calcium sulfate and ammonia to a stripper configured to recover the ammonia from the slurry; utilizing a heat source from a chilled ammonia process to the stripper; and extracting an ammonia vapor stream from the stripper. Also disclosed are systems for performing the processes. Also claimed is a process for recovering sodium hydroxide from a sodium sulfate stream by reacting the sodium sulfate stream with a lime slurry, separating the formed calcium sulfate in a thickener and extracting the sodium hydroxide from the thickener.
