降凝剂最佳始注入量的探讨

Discussion on the Determination of optimum Initial Treating Levels to Alter the Formatioa of Wax Crystals by Pour Point Depressant in Pipelines,

当原油降凝剂达到一定数量后,降凝剂在蜡析出时便与其中的绝大部分共晶,混合晶体在生长过程中为极化了的降凝剂分子集团所包围,蜡晶改进达到了相对稳定的状态。小于这个量可引起原油流变的急剧变化,大于这个量则不会再引起原油粘度和凝点的大幅度下降。据此,作者提出了最佳始注入量的概念。这对于在注入量的筛选中加快速度将起到良好的作用。

When the treatment leyels of wax crystal .modifier in crude3 are higher than certain level, It will corerystalize with wax crystals, In the growth process, mixed cocrystals will be suirounded by polarized molecular groups and the sgstems will fall into saturation. Therefore, the rheological behavior will change. But, if treatment levels are lower than this, the viscosity and pour point will not significantly reduce, Occordingly, the author establishes a guideline of optimal initial treatment level which will be useful to make good choice of treatment level for a given wax crystal modifier
