硫磺制酸装置节能环保实践

Practice of Energy-saving and Environmental of Sulphur-burning Sulphuric Acid Plants

介绍威顿(中国)化工有限责任公司两套400 kt/a硫磺制酸装置环保节能项目。项目包括:变频泵的大量使用、选用汽机动主风机并进行提效改造、增加HRS系统、优化转化器结构和触媒装填、氨——硫铵法尾吸、熔硫排汽及疏水回收等。现装置每吨标酸电耗<17 kWh、水耗<2.4 t、产汽率1.65 t;装置转化率>99.8%;尾气SO2<50 mg/cN3。建议硫酸装置的设计和建造,综合考虑节能环保项目的同步实施。

were described. blower＇s impelle Two 400 kt/a sulphur - burning sulphuric acid plants of energy - saving and environmental in Wyhon Co. Using such as frequency conversion technology in pump, turbine driving the main blower and optimum r, HRS, optimizing the structure of converter and catalyst loading, ammonia - acid process for exhaust emission, recycling steam condensate, etc, the opration per ton acid of plant with 〈 17 kWh, 〈 2.4 t water and 1.65 t steam production, average conversion efficiency was over 99.8%, and SO2 concentration in tail gas was less than 50 mg/CN3. Considering simultaneous implementation of energy saving projects, the design and construction of sulfuric acid plants were suggested.
