聚脂胺原油破乳剂的合成及性能的测定

Synthesis and Preliminary Performance Evaluation of Polyurethane Demulsifiers for Crude Oil

聚脂胺系列原油破乳剂的合成方法，得到三个系列聚脂胺型破乳剂，并用红外表征．室内破乳试验表明：这类破乳剂破乳能力强、破乳速度快、药用量低、对原油的适应性能力强，取得了良好的破乳效果．

We report the synthesis of polyurethane as crude oil demulsifiers. We obtained three trains of polyurethane demulsifiers and determined by IR. The preliminary laboratory tests show that the polyurethane demulsifiers prepared possess excellent emulsion breaking capacity in the dehydration of Liaohe crude oil.These demulsifiers all work well.
