影响煤油型溶剂油气味的因素

Factors Affecting Odor of Solvent Oil of Kerosene Type

溶剂油的气味是影响其用于特殊行业的主要障碍,这种气味除与其含有的硫、氮化合物等杂质有关外,烃族组成也是影响溶剂油气味主要因素,特别是单环环烷烃是脱除硫、氮杂质后溶剂油气味的主要来源。通过采用加氢精制-分子筛脱蜡组合技术,用分子筛将链烷从溶剂油中分离出来,满足了产品对气味的要求。

Odor of solvent oil is the main barrier to its utilization in specific industries. In addition to the impurities it contains such as sulphide and nitrogen compounds, components of hydrocarbon series are also one of the main factors that influence the odor of solvent oil. Especially, monocyclic naphthenes are the main causes of odor of solvent oil after removing impurities of sulfite and nitrogen. Alkane is removed from solvent oil by using molecular sieve and through the combination of hydrofining technology with molecular sieve de-waxing technology, which meets the requirements for odor of products.
