摘要
针对加剂轻柴油在储运过程中普遍存在蜡沉积现象导致冷滤点分布不匀而影响使用的问题,以中石化济南分公司0号轻柴油为原料,以国产降凝剂与助剂为添加剂,进行了抗蜡沉积剂的筛选试验。通过低温储存试验,筛选出一种具有抗蜡沉积作用的助剂,将其与降凝剂调配成复合降凝剂,可抑制加剂轻柴油的蜡沉积。通过变温储存试验可知,采用搅拌与倒罐的措施可使复合降凝剂的抗蜡沉积能力完全恢复。
During transportation the wax deposition of diesel fuel containing flow improver often occurs, which leads to non-uniform cold filter plugging point and affects use. The screening test of additives for suppressing wax deposition was carried out using 0^# diesel fuel produced by Jinan Company, various domestic flow improvers and co-additives. Storage tests at low temperature were carried out and a kind of co-additive having the function of suppressing wax separation was selected. It could be used with pour point depressant to form a complex flow improver to suppress the wax separation from diesel fuel. Storage test results at various temperatures showed that stirring and transfer of tank could fully recover the complex function of suppressing wax deposition.
