摘要
合成了原油降凝剂A,然后和高级脂肪胺进行胺解反应得到高效原油降凝剂B,在大港油田的原油中分别加入质量分数为200×10-6的降凝剂A和B,使原油凝固点分别下降10℃和24℃.在任丘、大庆、新疆油田中试验也有明显的降凝作用.文中还对胺解条件进行了研究,当高级脂肪胺的碳数为20时,在90℃下反应5h获得的降凝剂B的降凝效果最好.
Crude oil pour point depressant A was synthesized and the product A was aminolyzed into the oil retarding agent B by high alkyl amines. When agent A and B are added to crude oil from Dagang oil field respectively which concentrations are 200×10^(-6), the crude oil freezing point is lowered 10 ℃ and 24 ℃ respectively. The reaction conditions of the aminolyzation are studied .It is observed that when the number of the carbons in high alkyl amines is 20 and the reaction is taken place at 90 ℃ for 5 h, the retarding result of pour point depressant B is the best.
