Product introduction
 

一、 适用范围

  1.常减压装置

二、产品简介

本缓蚀剂是针对国内炼厂加工含硫及高酸原油的而研制生产的专用缓蚀剂。此缓蚀剂经精确复配后,在金属表面吸附性好,空间排列整齐,能在金属表面形成比一般缓蚀剂更加致密的保护膜,抑制腐蚀的进行。当 HCl-H2S-H­­­­2O型物质存在时,缓蚀剂改变金属表面的电荷状态,增大了腐蚀反应的活化能,使腐蚀难以进行;另一方面非极性基团多数排列在金属表面,形成疏水膜,阻止了与腐蚀反应有关的大部分电荷或腐蚀介质移动,达到抑制腐蚀的目的,达到缓蚀的目的,缓蚀率大于98%。对初馏塔,常减压塔顶部塔板、馏出线、冷凝冷却器等设备管线有优良的缓蚀性能。

本剂有水溶性和油溶性两种,可根据装置的实际情况选用。

四、用途及使用方法

1.配合液氨使用,调节PH值在6-9之间。

2.用脱盐水(水溶性)或柴、煤油(油溶性)15-20均匀稀释后,用计量泵连续注入塔顶冷凝系统。按系统处理量的20--35ppm注入,前期注入量为正常期的二倍,三天后每天依次按5ppm的速度递减至正常使用量。

3.本剂冬天使用时可适当用蒸汽加热。

五、包装与储运

产品分25kg桶和200kg桶两种包装。宜放阴凉通风处,不可靠近明火。文明装卸,不可撞击。

六、安全注意事项

  使用本品者应戴乳胶手套及防护眼镜。如遇本物触及皮肤时可用大量水冲洗后再用肥皂洗净即可;如遇本物品溅入眼睛请在现场立即用水充分清洗之后再请医生检查处理;如遇火灾,可用1211、干粉、泡沫、CO2 等灭火器以及黄砂灭火。油溶性缓蚀剂不可用水灭火。
