摘　　要：实沸点蒸馏数据作为原油评价工作的核心数据,是炼厂设计、原油加工流程制订的主要依据,对常减压蒸馏装置生产也能起到一定的指导作用,但是实际生产过程中常减压装置各侧线产品采用恩氏蒸馏进行馏程分析,由于两种蒸馏方式不同等原因,造成实沸点蒸馏数据不能直接指导装置生产。本研究利用同种馏分油开展两种馏程分析,对所得数据进行拟合,得出相关转化关系式,实现了实沸点蒸馏与恩氏蒸馏的馏程转化。As the core data of crude oil evaluation,the real boiling point distillation data is the main basis for refinery design and crude oil processing process formulation,and can also play a certain guiding role in the production of atmospheric and vacuum distillation units.However,in the actual production process,the products on each side of atmospheric and vacuum distillation units are analyzed by using Engler distillation.Due to different distillation methods and other reasons,the real boiling point distillation data cannot directly guide the production of the unit.This study carries out two distillation range analysis using the same distillate oil,fits the data obtained,and obtain relevant conversion relationship,so as to realize the distillation range conversion between true boiling point distillation and Engler distillation.
