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40mg/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60mg/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 For the 40mg / L can be completely removed dissolved oxygen in raw water, but the follow-up will have a negative impact on the boiler. From safety and environmental considerations, it is recommended to use dimethyl ketoxime as oxygen scavenger, the amount of 60mg / L.
