使用KQ-1缓蚀阻焦剂,减轻糠醛装置腐蚀和结焦

独山子炼油厂糠醛精制装置设备腐蚀状况严重 ,尤其是加工高酸值原料 ,更加剧了设备的腐蚀。通过对腐蚀原因分析 ,决定从工艺防腐上解决 ,提出了加入缓蚀剂减缓设备腐蚀的方法 ,在实验室评价和工业装置中 ,评选了四种糠醛精制装置的缓蚀剂 ,其中KQ 1作为装置缓蚀剂效果最佳 ,平均缓蚀率达到 4 4 .5 % ,并估算了KQ 1工业使用的经济效果

Reduce corrosion and cocking by using KQ-1 inhibitor in lubricating oil unit

The equipment corrosion was very severity in furfural refining lubricating oil unit of Dushanzi petroleum refinery especially dealing with high acid number stock. By analyzing corrosion reason, we decide to reduce corrosion by inhibitor , we had selected and tested four kinds of inhibitor for furfural lubricating oil unit,the result of KQ 1 is the best . We also valuated the beneficial result using KQ 1 in the unit.
