Abstract

The invention belongs to the field of petroleum refining, particularly relates to a fractionating tower, a fractionating system and a method for producing heat conducting oil. The fractionating tower comprises a tower body, wherein a tower bottom liquid outlet, a stripped vapor inlet, a feed port and a tower top steam outlet are orderly arranged on the tower body from bottom to top, a tower body inner cavity is divided into a plurality of fractionating sections through a plurality of oil collecting tanks along the vertical direction, the oil collecting tanks are arranged between the feed port and the tower top steam outlet, a packing layer is arranged between two adjacent oil collecting tanks, and at least a packing layer is filled with structured packing. The fractionating sections of the fractionating tower can promote raw oil steam to fully transfer mass and heat between steam and liquid phases during the fractionating process by arranging the packing layers which are provided with the structured packing, thereby improving fractionating effect of raw oil in the fractionating tower, and improving yield and performance index of heat conducting oil products which are obtained by fractionating and refining.

Description

technical field [0001] The invention belongs to the field of petroleum refining, and in particular relates to a fractionation tower, a fractionation system and a heat transfer oil production method. Background technique [0002] Heat transfer oil is the former name of "heat carrier oil" in GB / T4016-1983 "Terms of Petroleum Products". The English name is Heattransferoil. [0003] Heat transfer oil has the performance of anti-thermal cracking and chemical oxidation, good heat transfer efficiency, fast heat dissipation, and good thermal stability. As an industrial oil heat transfer medium, heat transfer oil has the following characteristics: under almost normal pressure conditions, a high operating temperature can be obtained. That is, using heat transfer oil as the heat transfer medium of industrial oil can greatly reduce the operating pressure and safety requirements of the high-temperature heating system, and improve the reliability of the system and equipment; it can meet ...
