Product introduction

一、   適用范圍

1.常減壓裝置

二、   產品簡介

國內煉廠在加工較劣質原油時,多采用液氨作為中和劑,隨著原油性質的變差,液氨用量不斷增加,生成的銨鹽所產生的垢下腐蝕日益嚴重。本緩蝕劑是針對此情況,用有機多胺增鏈合成,再經精確復配。本劑的主要優點有:1.極性基團成膜更加致密,排列更加整齊,非極性基團疏水膜更耐沖刷。2.沸點較高,PH值更易控制,可以很好地控制在6.57.5的范圍以內;實驗表明,塔頂p H 值在6. 57. 5 的范圍內腐蝕最輕,當p H 值小于6 , HCl 的腐蝕性加強,p H 值大于 8 ,H2 S 的腐蝕作用增強。3.有效避免了生成N H4 Cl N H4 HS導致的垢下腐蝕。此緩蝕劑緩蝕率大于98%,經在多家煉廠使用,得到了很高的評價,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。

三、質量技術指標
