Abstract

Poly(1-hexene-co-maleic anhydride) derivatives containing various lengths of linear alkyl side chains (C₁₁–C₂₂) were experimentally evaluated as drag reduction agents in the turbulent flow of Iraqi crude oil using a circulating flow loop system. Good drag reduction performances were obtained. The results showed that the drag reduction has been influenced by the flow rate, concentration, chemical structure, molecular weight, and temperature. Their mechanical stabilities were also investigated using a cylindrical rotator device, and a good relationship was obtained between copolymers' drag reduction efficiency and branch length, in which longer branches significantly enhance copolymer mechanical stability.

摘要

聚（1-己烯-共-马来酸酐）衍生物含有不同长度的直链烷基侧链（C ₁₁ -C ₂₂），使用循环流回路系统在伊拉克原油的湍流中作为减阻剂进行了实验评估。获得了良好的减阻性能。结果表明，减阻受流速、浓度、化学结构、分子量和温度的影响。还使用圆柱形旋转装置研究了它们的机械稳定性，并且在共聚物的减阻效率和支链长度之间获得了良好的关系，其中更长的支链显着提高了共聚物的机械稳定性。
