摘要
分析了聚α-烯烃润滑油(PAO)技术发展的背景及PAO产品的特点,介绍了适用于热敏性物系的高真空精馏和分子蒸馏技术的特点。根据PAO产品的分子结构、理化性质及合作研究单位提供的精馏实验报告,采用高真空精馏技术对PAO产品的分离单元进行流程开发。PAO产品高真空精馏成败的关键是合理设计填料塔、降膜再沸器、抽真空系统及塔顶冷凝设备。运用PRO/Ⅱ软件对PAO产品分离工艺进行模拟计算,模拟结果可作为工程化设计的基础数据。
The technology development background of poly α-olefin (PAO) lube oil and the characteristics of PAO products are analyzed. High vacuum distillation and molecular distillation technology are suitable for the separation of heat-sensitive substances. According to the molecular structure and physicochemical properties of the PAO products, as well as the distillation experiment report provided by the cooperative research unit, the high vacuum distillation technology is used to develop PAO products separation process. The key of high vacuum distillation of PAO products is the reasonable design of packed tower, falling film reboiler, vacuum system and the overhead condenser. The PAO products separation process is simulated by PRO/Ⅱ, and the simulation results can be used as the basis data of engineering design.
