摘要
原油降凝剂(OEAM)是丙烯酸正十六醇和正十八醇混合酯与马来酸酐的共聚物。本文介绍了降凝剂(OEAM)的合成方法。考察引发剂用量,聚合温度和反应时间对聚合物收率和降凝效果的影响。结果表明,当加剂量为0.5％～1.0％(重量),预热温度为50℃时,使鲁宁混合原油倾点下降11～12℃。粘度降低率为43％。
Pour depressant OEAM, is a copolymer of maleic anhydride and mixed hexadecyi propionate and oc-tadecyl propionate. The synthetic method of OEAM wasstueied. The effect of amount of initiator,po|ymerizatinntemperature and reaction time on the product yield andpour depression effect was investigated. It is shown thatthe pour point of Shengli-Zhongyuan crude oil at 50'C de-creased by 11 to 12C and its viscosity decreased by 43％when the added amount of OEAM was 0. 5％ to 0. 1％(mass).
