What are the characteristics of 150BS produced from different crude oils?
Thread Content
As the title suggests: 150BS is produced using both paraffinic-based crude oils and naphthenic and intermediate-base crude oils. Paraffinic-based oils are more commonly used, but can the properties of 150BS produced from different crude oils be identical in all aspects?
Firstly, not all crude oils can be used to produce 150BS. Secondly, to produce qualified 150BS, different processes are required for different types of oil. To answer what the differences are, first of all, 150BS produced by different processes varies; for example, that produced by purely physical methods is classified as Category I oil, while oil produced through full hydrogenation or a combination of hydrogenation and physical methods falls into Category II or higher. To achieve 150BS, the viscosity must be appropriate, as must the stickiness. Stickiness essentially reflects the chemical composition; for example, oils produced through the full hydrogenation of naphthenic base oils have high viscosity and good light stability. Bright oils produced in Jinan using physical and hydrogenation methods can also meet the 150BS requirement.
