8B航空喷气机润滑油工艺条件的优化

Optimization of Technological Conditions to Increase Yield of 8B Aviation Jet Lubricant

研究了抚顺化塑厂合成润滑油装置（五套配套装置）生产8B航空喷气机润滑油工艺条件的优化。实验结果表明,影响8B航空喷气机润滑油质量和收率的主要因素有：α-烯烃的组成、反应温度、反应时间、催化剂的质量分数以及分馏装置操作等。同时,通过对后续聚合装置、常减压装置等工艺条件的优化,可使8B航空喷气机润滑油基础油的质量分数由原来占常减压馏分的12%-15%,提高到17%-19%,较大地提高了装置的综合收益,每生产1 000 t8B航空喷气机润滑油,可节约4 800 t原料石蜡,经济效益显著。

The technological conditions of lubricant synthesizing devices（five sets of coordinated equipment） of Fushun Chemical Plant was investigated in order to increase 8B aviation jet lubricant yield.The practical production and experiment indicate that the primary factors influence the yield and quality of 8B aviation jet lubricant are： composition of α-alkene,temperature of polymerization reaction,time of polymerization reaction,proportion of activator and operation of fractionating device.In the process of production and experiment,high quality paraffin is used to optimize the technological conditions of paraffin decomposition device in order to acquire higher quality α-alkene.Meanwhile,mass fraction of 8B aviation jet lubricant base oil can be boosted from 12%~15% increase to 17%~19% in normal decompressing fractionation through the optimization of technological conditions for subsequent polymerizing device and normal decompressor.It can greatly increase comprehensive economic profit of the device.This means that 4800 tons of paraffin material can be saved in producing every thousand tons of 8B aviation jet lubricant,and corresponding it has obvious economic benefits.
