SN500 Base Oil is a type of mineral oil that is commonly used as a lubricant[6]. It is a light-grade base oil at the upper end of the specifications for Grade I base oils[2][4]. SN500 has a viscosity of 10.1-11 cSt at 100°C and 94-98 cSt at 40°C[1]. It is the most widely used base oil[1].
SN500 is mainly used in lubricant production[2][4]. It is also used in rubber processing as a processing oil[3]. SN500 has undergone solvent refining to remove impurities[5]. It is produced and sold by various companies worldwide, including Sepahan Oil Company, Behran Naft Pars, and DYM Resources[1][5].
Origin and Production Process
SN500 Base Oil is produced by refining crude oil[3][5]. The production process involves distillation, solvent refining[3], and solvent and wax extraction processes[2]. The crude oil is heated and separated into several fractions[5]. The SN500 Base Oil is then highly refined through a process of distillation that removes impurities such as water, dirt, and other contaminants[4]. The refining process is finished by hydrogenation[6]. The SN500 Base Oil is a base oil that has been produced since the 1930s[1].
Distillation and Hydroprocessing
The production process of SN500 Base Oil involves distillation and hydroprocessing. Here are the steps involved in the production process of SN500 Base Oil:
1. Vacuum distillation: The oil from the gasoil stripper is sent to vacuum distillation to recover vacuum distillate oil fraction from “heavier than” contaminants[1].
2. TFE and Fractional continuous distillation: The oil is then subjected to TFE and fractional continuous distillation to generate different base oil distillates[2].
3. Refining: The base oil distillates are then refined for good color or even watercolor base oil[2].
4. Hydrotreatment: The heavy hydrocarbon stream is subjected to hydrotreatment and selective hydrogenation at optimized process conditions[3].
5. Hydrogenation: The mixture of deasphalted bottoms and unpressable distillate is combined with fresh hydrogen and recycled hydrogen flowing through a conduit. The mixture is then hydrogenated to remove toxic nitrogen and sulfur compounds, as well as other oxides present in the chemical[4][5].
6. Oil distillation under reduced pressure: The final step is oil distillation under reduced pressure, which is done until 250ºC[6].
The above steps result in the production of highly refined SN500 Base Oil.
