摘要
以高粘度基础油为原料,采用两段加氢工艺,生产合格的高粘度食品级白油。第一段加氢主要脱除原料中硫、氮等杂质,并饱和部分芳烃;第二段加氢采用更高压力20MPa饱和全部芳烃,达到食品级白油产品,其质量符合国外同类产品标准。
This article introduces production of high viscosity white oil. It adopts two stage hydrogenation technology ,uses high viscosity basic oil materials. The first stage hydrogenation,gets out of sulphur,nitrogen etc. impurity from materials and saturate part of aromatic hydrocarbon. The second stage hydrogenation,adopts higher pressure 20 Mpa and saturate all aromatic hydrocarbon,comes up to food grade white oil. The quality accoreds with standards of foreign similar products.
