1.	Meessen, Jo, et al. (author) Process for the reduction of ammonia emissions in a urea manufacturing process 2011 Patent (pop. science, debate, etc.)abstract The present invention relates to a process for removing ammonia from an effluent of an ammonia enriched gaseous stream formed in or downstream the finishing section of a urea manufacturing process, said ammonia enriched gaseous stream comprising 200 mg NH 3 /Nm 3 or less, wherein the ammonia enriched gaseous stream is contacted with an aqueous composition comprising phosphoric acid thereby producing an ammonia enriched liquid effluent, wherein a bleed of the ammonia enriched liquid effluent is subjected to a urea decomposition step. The present invention also relates to a process for producing an ammonium phosphate essentially free of contaminants, said process comprising the following steps: (a) contacting an ammonia enriched gaseous stream comprising 200 mg NH 3 /Nm 3 or less with an aqueous composition comprising phosphoric acid thereby producing an ammonia enriched liquid effluent; and (b) subjecting a bleed of the ammonia enriched liquid effluent to a urea decomposition step.
