1999年 4月份以来 ,洛阳石油化工总厂生产的喷气燃料出现色度不稳定现象。经过调查分析 ,主要原因是进厂的中原原油和新疆原油质量下降 ,且进厂原油比例不均 ,原油变重 ,含硫量高。原有的喷气燃料精制装置氧化锌精制效果不好 ,注碱量和注水量较小 ,精制的喷气燃料颜色深 ,达不 Since April 1999, the jet fuel produced by Luoyang Petrochemical Plant has instable chromaticity. After investigation and analysis, the main reason is that the quality of the Central Plains crude oil and Xinjiang crude oil entering the plant has declined, and the proportion of the crude oil into the plant has been uneven.
