Group II. Originating in 1971, a better grade of petroleum base oil, which may be partially produced by Hydrocracking. All impurities will be removed from the oil leading to clearer color. The amount of total sulfur in a crude oil depends on the type of oil field and it varies from 0.05% to 14%. Of course, sulfur values as low as 0.2% are enough to create sulfidation corrosion in plain steels and low alloy steels. These kinds of steels are often used in several parts of refinery units. Standard test methods (ASTM and others) for crude oil properties 0.002 - 4 wt% total sulfur in crude oil. Back to Content Boiling and melting points, density, structure and molweight of organic sulfur compounds. Based on the stoichiometry of the reaction, one mole of iodine reacts with one mole of water, thus the quantity of water is
Clearly, sulfur content impacts OIT as base oil SN 150 A has a higher sulfur content compared to the new range 150 (NR 150) and withstand severe oxidation longer (Figure 1). Doping NR 150 with a model sulfide compound to 700 ppm S and further to 0.3 wt% S increases the OIT significantly, resulting in excellent oxidation stability.
Sulphur based oil is from the middle east and parafin based oil is from the Pennsylvania. For heat treat I like parafin based. When the sludge of middle eastern oil meets with water it forms a sort of sulpuric acid and thins out valve stems wheere the sludge is. That don't happen with parafin based oils. Sulfur is used in many EP oils and metal-working fluids as an EP additive. The basic way this works is for the sulfur to react at elevated temperatures, such as those experienced by meshing gears to form a sulfide layer. For example, for steel gears, an iron sulfide layer forms on the gear tooth surface. Crude oil with low sulfur content is classified as “sweet;” crude oil with a higher sulfur content is classified as “sour.” Sulfur content is considered an undesirable characteristic with respect to both processing and end-product quality. Therefore, sweet crude is typically more desirable and valuable than sour crude. Base oils are classiﬁed by the Ameri- can Petroleum Institute into ﬁve groups (see Figure 1) according to their ingre- dients and performance characteristics. Group I base oil stocks contain greater than 0.03% sulfur, less than 90% saturates and have a VI ranging from 80-119. Group I base oils are classified as less than 90 percent saturates, greater than 0.03 percent sulfur and with a viscosity-index range of 80 to 120. The temperature range for these oils is from 32 to 150 degrees F. Group I base oils are solvent-refined, which is a simpler refining process. How Sulfur Content in Diesel Fuel Impacts Engine Oil Formulation Apr 26, 2019 | Applications , End Uses , Off-Highway , On-Highway Diesel fuel contains sulfur which derives from the original crude oil source and can still be present after refining. All lubricants consist of a base oil. Normally, lubricants consist of 90% base oil and 10% additives. The American Petroleum Institute’s (API) has categorized base oils into five groups which are specified by the saturate level, sulfur level, and viscosity index. Saturate Level. Saturates are a type of molecule commonly found in base oil.
