              一、 適用范圍

                1.常減壓裝置

              二、產品簡介

              本緩蝕劑是針對國內煉廠加工含硫及高酸原油的而研制生產的專用緩蝕劑。此緩蝕劑經精確復配后,在金屬表面吸附性好,空間排列整齊,能在金屬表面形成比一般緩蝕劑更加致密的保護膜,抑制腐蝕的進行。當 HCl-H2S-H­­­­2O型物質存在時,緩蝕劑改變金屬表面的電荷狀態,增大了腐蝕反應的活化能,使腐蝕難以進行;另一方面非極性基團多數排列在金屬表面,形成疏水膜,阻止了與腐蝕反應有關的大部分電荷或腐蝕介質移動,達到抑制腐蝕的目的,達到緩蝕的目的,緩蝕率大于98%。對初餾塔,常減壓塔頂部塔板、餾出線、冷凝冷卻器等設備管線有優良的緩蝕性能。

              本劑有水溶性和油溶性兩種,可根據裝置的實際情況選用。

              三、質量技術指標

              四、用途及使用方法

              1.配合液氨使用,調節PH值在6-9之間。

              2.用脫鹽水(水溶性)或柴、煤油(油溶性)15-20均勻稀釋后,用計量泵連續注入塔頂冷凝系統。按系統處理量的20--35ppm注入,前期注入量為正常期的二倍,三天后每天依次按5ppm的速度遞減至正常使用量。

              3.本劑冬天使用時可適當用蒸汽加熱。

              五、包裝與儲運

              產品分25kg桶和200kg桶兩種包裝。宜放陰涼通風處,不可靠近明火。文明裝卸,不可撞擊。

              六、安全注意事項

                使用本品者應戴乳膠手套及防護眼鏡。如遇本物觸及皮膚時可用大量水沖洗后再用肥皂洗凈即可;如遇本物品濺入眼睛請在現場立即用水充分清洗之后再請醫生檢查處理;如遇火災,可用1211、干粉、泡沫、CO2 等滅火器以及黃砂滅火。油溶性緩蝕劑不可用水滅火。
