A process for producing ammonia and sulfuric acid from a stream comprising ammonium sulfate is provided. The process comprises the steps of heating the stream to produce ammonia and a decomposition product comprising one or more than one of a bisulfate salt, a pyrosulfate salt, or a combination thereof. The ammonia produced is recovered, and water is added to the decomposition product to produce a stream comprising the decomposition product. The stream comprising the decomposition product is processed by acid retardation to obtain a sulfuric acid stream and a stream comprising one or more than one sulfate salt.
提供了一种从含硫酸铵流中生产氨和硫酸的工艺。该工艺包括以下步骤:加热该流以产生氨和分解产物,其中分解产物包括一种或多种硫酸氢盐、焦硫酸盐或其组合物。回收所产生的氨,向分解产物中加入水以产生含分解产物的流。通过酸滞后处理含分解产物的流,以获得硫酸流和含一种或多种硫酸盐的流。
