摘　　要：针对硫化氢制酸两种工艺的余热利用方案,从余热利用设备的结构特点、工艺指标以及热工检测仪表等方面,比较了两种工艺流程的余热利用情况。湿法制酸的投资虽较高,但产汽量高,推荐采用硫化氢湿法制酸的余热利用方案。The schemes of waste heat utilization in two H2S-based sulfuric acid production technologies in terms of construction features of waste heat utilization equipment,process figures,thermal detection and monitoring instruments,etc.are compared.The wet-method sulfuric acid production requires bigger investment,but it produces more steam,so,it is recommended to use the waste heat utilization scheme of wet-method H2S-based sulfuric acid production.
