200号溶剂油脱氮精制
Study on Technology of Denitrification for 200~# Resolvent Nap htha
【摘要】 采用固定床吸附和液相脱氮两种方法对直馏 2 0 0号溶剂油进行了脱氮实验 ,并对脱氮后溶剂油外观、色度进行对比。精制后溶剂油外观为无色透明 ,赛氏色度不小于 +2 5 ,液相脱氮精制的溶剂油的外观性能更加稳定 ,储存安定性好。
【Abstract】 After denitrifing 200~# resolvent naphtha by fixed b ed ed absorption and liquid phased denitrification, we compare appearance and colou r after and before denitrification and find they look transparent and the values of saybolt colour are not less than+25. The resolvent naphtha after liquid phas ed denitrification looks more stable.
