viscosity pour point

The hydrocracking tail oil possesses the characteristics of higher viscosity index, pour point, viscosity and lower sulfur, nitrogen, impurity content.

加氢裂化尾油粘度指数高，低硫、低氮、杂质含量少，倾点和粘度偏高。

The operation result showed that the lube base oil products with high viscosity index and low pour point were produced from the 2nd and 4th vacuum column side cuts and the deasphalted oil of Daqing crude oil.

结果表明，以大庆原油的减二线、减四线和轻脱沥青油为原料，得到了粘度指数高、倾点低的润滑油基础油产品。

It features high anti-wax effect, high temp. resistance and pour point and viscosity reduction.

其主要特点是 防 蜡率高,耐高温性好, 且同时兼具防蜡、降凝、降粘等多种功能.

Prediction of oil temperature and heat balance calculation are required in handling and transporting high viscosity and high pour point oil by heat treatment.

本文利用微机对高粘、高凝油品的推定温度和热平衡进行计算，编制出程序，并将涉及到的有关资料贮入数据库。
