450万常减压蒸馏装置3~#喷气燃料精制生产过程分析

Analysis on 3~# Jet Fuel Refining Production Process in 4.5 Mt/a Atmospheric and Vacuum Distillation Unit

介绍了大连石化450万t/a常减压蒸馏（以下简称二蒸馏）装置生产3~#喷气燃料的精制过程。依据吸附原理和实际生产操作数据,着重分析了影响3#喷气燃料硫醇性硫含量及赛波特比色产品质量的主要原因。指出了原油性质、反应温度、注风量、空速、装填效果、吸附剂质量等是导致吸附剂寿命的主要因素。

3~# Jet fuel refining production process in 4.5 Mt/a atmospheric and vacuum distillation unit was introduced. And influencing factors of thiol sulfur content and Saybolt color of 3~# jet fuel were analyzed based on the adsorption mechanism and practical operation data. It＇s pointed out that crude properties, reaction temperature, air injection rate, air volume, loading effect and adsorbent quality are the main reasons to affect adsorbent life.
