BASE OIL - HUILE DE BASE
Base oils are used to produce products including greases, motor oil and other processing fluids. Different products require different compositions and properties in the oil. One of the most important factors is the liquid’s viscosity at various temperatures. Whether or not a crude oil is suitable to be made into a base oil is determined by the concentration of base oil molecules as well as how easily these can be extracted.
Base oil is produced by refining crude oil. This means that the crude oil is heated in order that various distillates can be separated from one another. During the heating process, light and heavy hydrocarbons are separated – the light ones can be refined to make petrol and other fuels, while the heavier ones are suitable for bitumen and base oils.

ULTRA LANDER RECYCLED - RE-REFINED BASE OIL
|Sn 500||Sn 350||Sn 150|
Waste oil refineries (WOR) is done by different methods , in the near past refineries used clay and acids for refine the waste oil , but in this method , residual materials were burned and make more pollution.
Now the new methods is using:
- Distillation column with vacuum + clay treatment
- Distillation column with vacuum + chemical treatment
- Hydrogen pre-treatment + vacuum distillation
In Ultra Lander we use distillation column with vacuum + clay treatment , also Ultra Lander R&D is testing to start a WOR refining using distillation column and the Nano-Technology
Shipment is done in metallic drum directly in 20' containers , but it is possible for huge quantity to supply on pallet directly in the cargo bulk vessel.
Qty per 20' ctner : 80 Barrels 180 Kg/Barrel

WHAT IS base oil ?
There are large numbers of crude oils are used to produce base oils. By using hydrogenation technology, in which sulfur and aromatics are removed under high pressure, we can obtain extremely pure base oils, which are suitable when quality requirements are particularly stringent.
Chemical substances and additives are added to the base oil in order to meet the quality requirements for the end products in terms of,
The American Petroleum Institute (API) has categorized base oils into five categories (API 1509, Appendix E). The first three groups are refined from petroleum crude oil. Group IV base oils are full synthetic (polyalphaolefin) oils. Group V is for all other base oils not included in Groups I through IV. Before all the additives are added to the mixture, lubricating oils begin as one or more of these five API groups.
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. This is why they are the cheapest base oils on the market.
Group II base oils are defined as being more than 90 percent saturates, less than 0.03 percent sulfur and with a viscosity index of 80 to 120. They are often manufactured by hydrocracking, which is a more complex process than what is used for Group I base oils. Since all the hydrocarbon molecules of these oils are saturated, Group II base oils have better antioxidation properties. They also have a clearer color and cost more in comparison to Group I base oils. Still, Group II base oils are becoming very common on the market today and are priced very close to Group I oils.
Group III base oils are greater than 90 percent saturates, less than 0.03 percent sulfur and have a viscosity index above 120. These oils are refined even more than Group II base oils and generally are severely hydrocracked (higher pressure and heat). This longer process is designed to achieve a purer base oil. Although made from crude oil, Group III base oils are sometimes described as synthesized hydrocarbons. Like Group II base oils, these oils are also becoming more prevalent.
Consists of synthetic oils made of Poly-alpha-olefins PAO.
Poly-alpha-olefins PAO oils are much more stable in extreme temperatures, which make much more suitable for use in very cold weather (as found in northern Europe) as well as very hot weather (as in Middle East).
Any type of base oil other than mentioned in the previously defined groups.
They include, among others, naphthenic oils and esters
