硫酸装置低温余热回收运行总结

Summary of low temperature waste heat recovery operation in sulphuric acid plant

介绍了硫酸低温热回收装置的主要设备、工艺流程和运行情况,重点介绍了装置回收热量、产气率和经济效益。低温热回收装置蒸汽产量约14 237 kg/h,可节省除氧蒸汽1 662 kg/h,同时干吸工序可节省循环水约900 t/h。针对运行中出现的问题,技术人员采取相应改进措施,确保硫酸低温热回收装置长周期稳定运行。

The main equipment,process and operation of sulphuric acid plant for low temperature heat recovery were introduced.The heat recovery,gas production rate and economic benefits of the device were introduced emphatically. The steam output of the low temperature heat recovery unit is about 14 237 kg/h.It can save 1 662 kg/h steam in deoxidization section,and about 900 t/h of circulating water in drying and absorption section. In view of the problems occurring in the operation,the technicians take corresponding measures to ensure the long and stable operation of the thermal recovery of sulphuric acid plant.
