丙烷脱沥青装置优化运行研究

Study on the Optimum of Propane Deasphalting Unit

溶剂脱沥青工艺作为加工重油的主要工艺之一,具有不可替代的作用与地位。当前我国交通事业迅速发展,用环烷基原料油经溶剂脱沥青工艺,在生产润滑油基础油的同时还可生产各种牌号道路沥青。针对丙烷脱沥青装置建成后面临的加工量制约问题,通过增设消泡剂系统、空冷器,增加水冲洗、循环柴油冲洗系统,新建沥青闪蒸罐等一系列方法,使丙烷脱沥青装置加工量提高到设计值。

Crude oil deep processing is an important in the oil refining industry. Solvent deasphahing process, as one of the main process of heavy oil, plays an irreplaceable role. Along with the rapid development of transportation in our country, solvent deasphalting process use the naphthenic base oil as raw materials, not only produce lubricating oil, but also produce all kinds of brand road asphalt. In this paper, we introduced the present situation of our asphalt processing, elaborated the propane deasphahing processing capacity constraints after the completion of new device. By adding deforming agent system, air cooler, increasing water flushing, cycle diesel oil flushing system, building new asphalt flash tank and so on, we increased the propane deasphalting unit processing quantity to the design value, to make the company get more benefit.
