| 摘 要： | 介绍了云南云天化国际化工股份有限公司云峰分公司硫酸厂废热锅炉给水热力除氧系统存在的问题和改进措施。采用热力除氧辅助二甲基酮肟法化学除氧后,除氧水ρ(O2)≤0.015 mg/L,200 kt/a和300 kt/a硫酸装置锅炉水指标均达到正常生产要求。今后可考虑将热力除氧温度降低6～7℃,综合除氧成本将降低0.6元/t,预计改进后硫酸厂每年可节省运行费用约63万元。

| Abstract: | Problems and improvements of thermal deaeration system for waste heat boiler feed water in Yunnan Yuntianhua International Yunfeng Branch＇ s sulphuric acid plant are described.After using thermal deaeration-assisted chemical deaeration with dimethyl ketoxime,O2 concentration in treated water was lower than 0.015 mg/L and the boiler water met the normal production requirements of 200 kt/a and 300 kt/a sulphuric acid plants.The temperature of thermal deaerator shall be considered to lower 6-7 ℃ in the future,so the total deaerattion cost will be reduced 0.6 yuan/t and the operating cost will be saved about 630 000 yuan per year. |
