通过对苏里格某天然气处理厂目前使用的除氧剂无水亚硫酸钠、联氨及二甲基酮肟除氧效果进行了分析对比,实验结果表明:无水亚硫酸钠除氧效果最好,加量为40 mg/L即可完全去除原水中的溶解氧,但后续会对锅炉产生不利影响。从安全、环保综合考虑,建议采用二甲基酮肟为除氧剂,加量为60 mg/L。 By comparing and analyzing the deoxidizing effect of oxygen scavenger anhydrous sodium hydrate, hydrazine and dimethyl ketoxime currently used in a natural gas processing plant in Sulige, the experimental results show that the best scavenging effect of anhydrous sodium sulfite is Dissolved oxygen is completely removed from the raw water at 40 mg / L, but subsequently it can adversely affect the boiler. From safety and environmental considerations, it is recommended to use dimethyl ketoxime as oxygen scavenger in an amount of 60 mg / L.
