    摘要： The invention relates to a process of producing an ammonium salt composition. The process comprises the steps of providing a process stream comprising sulfuric acid and at least one tertiary amine contacting the process stream with ammonia under conditions effective to form a waste stream and a product stream. The waste stream comprises water, the tertiary amine, and ammonia and the product stream comprises a first amount of ammonium salt. The process further comprises the steps of deriving from the waste stream an off gas stream comprising a preliminary amount of ammonia and contacting the off gas stream with an acid under conditions effective to form an ammonium salt stream and a purge stream. The ammonium salt stream comprises a second amount of ammonium salt and the purge stream comprises a reduced amount of ammonia, which is less than the preliminary amount.
