WitrynaThe finest structure is present in the naphthenic oil grease. This may be correlated with the high optical clarity very smooth texture, and relative stiffness for a given soap content which are usually associated with lithium soap-naphthenic oil greases. FIG. 4. Effect of oil type on fiber structure of lithium stearate greases. Crude oil appears in a host of different forms, which in turn determine how it should be refined. Classification of the crude oil can vary, because different actors have different starting points. For refineries, the interest has been primarily focused on the distribution between the distillation fractions: petrol, paraffin, gas oil, lubricant distillate, etc. Refiners look at the density of the crude oil – whether it is light, medium or heavy – or the sulfur content, i.e. whether the crude oil is “sw…
