Items like lubricating greases, motor oil, and metal-processing fluids are made from base oils. Various applications of base oil require oils with varying qualities and formulations. At different temperatures, liquid viscosity is one of the most crucial aspects. The number of base oil molecules and the ease with which they may be removed decide whether or not crude oil is appropriate for making a base oil.
Crude oil must first be refined to create base oil. The crude oil must be heated to extract different distillates from one another. Light and heavy hydrocarbons are segregated during the heating; the former can be processed to produce gasoline and other fuels, whereas the latter is appropriate for bitumen and base oils.
The production of base oils requires a significant amount of crude oil, which is widely available worldwide. The most typical form is paraffinic crude oil, although naphthenic crude oils can produce items with superior viscosity and excellent characteristics at low temperatures. You can create light base oils utilizing new hydrogenation tech, which is useful when quality standards are stringent. Hydrogen and high pressure are used to eliminate sulfur and aromatics.
As a base oil exporter, we provide high-quality Iranian base oil by refining the best crude oil. Base oil exporters have announced that statistics show that the demand for Iranian base oil has increased. This has resulted due to various product lines derived from base oil.
Among the products manufactured from base oils are lubricating greases, motor oils, and metal processing fluids.
Each of these products requires a different oil composition and property. For this reason, the base oil is divided into multiple grades. As a base oil exporter, we export all types in all grades. Liquid viscosity at various temperatures is among the most critical factors. Base oil producer companies determine whether crude oil can be made into base oil based on the concentration of base oil molecules and the ease of extraction.
Refining crude oil leads to the production of base oil. It refers to heating the crude oil to separate it into its many distillates.
The base oil can be used either as recycled oil or virgin oil. In case base oil is re-refined, it is known as recycled oil.
Different types of first-class base oil can be obtained from different suppliers, by using the base oil specifications and checking the correctness of the specifications, it is possible to distinguish the right base oil from the unsuitable ones. We at Vira petroleum have provided the possibility of testing and checking the base oil for the buyers. Before buying, you can get a sample of the base oil product and make a purchase by checking the characteristics.

There are base oils with different qualities, and these quality differences depend on the type of crude oil and refining methods. According to the refining method and properties such as viscosity and sulfur content, base oils are classified into five main categories. Method In the following, we briefly describe the different methods of base oil refining.
Virgin base oil is the base oil that is produced when crude oil is refined. Following several applications, this oil then turns into used oil. The base oil’s properties allow for the creation of refined base oils with qualities practically identical to those of virgin base oil. In two respects, this issue is good for the environment. First, used and burned oils are not abandoned in the natural world. Second, it stops oil from being extracted excessively to make products like base oil. Recycled base oil is produced following the refinement of used base oil.
In 1935, used oils underwent a second refinement to become original base oils. “Re-refined” oils are those that have undergone a second refinement process. Low acceptance of these oils was due to several factors, including the significant expense of the process and, as a result, the high market value of the re-refined oils in comparison to the cost of the first refined oils, the inadequate disposal of carcinogenic poly-ring aromatics, the unseemly appearance of these oils, and the increasing complexity of base oil combinations and other lubricants in the engine oil. The products generated from the re-refining in 1998 barely covered 7% of the demand for base oil in Western Europe. With the growth of oil use around the globe, oil re-refining has been hotly debated. Forty years ago, it began in our country. If spent oil is recycled correctly, it can be reused, unlike most oil products that can only be used once before being destroyed.
A huge amount of crude oil is used in the production of virgin oil around the world. One of the most common types of crude oil is paraffinic. However, there are other types of crude oils, such as naphthenic, which produce very good products that are easier to dissolve and have better properties at low temperatures. It is possible to obtain pure virgin oils using hydrogenation technology, which involves removing sulfur and aromatic compounds with hydrogen under high pressure. This is ideal when quality requirements are extremely stringent. Every single step of this process is carefully monitored by our base oil export company.
The American Petroleum Institute (API) categorized base oils into five main categories in 1993. This breakdown is calculated based on the refining method and the properties of the virgin oil, including viscosity and sulfur content.
Based on API definitions, Group I is defined as “base stocks containing less than 90 percent saturates and greater than 0.03 percent sulfur and having a viscosity index not exceeding 80.”. Solvent-refined oils are the cheapest and least refined of the Group I oils. Solvent-refined oils are more easily refined, and they use a simpler process. In solvent-refined oils, different hydrocarbon molecules are mixed that cannot be separated in refinement. Consequently, the oil will contain irregular molecules, which leads to increased friction. This is why Group I oils are often used for low-demand applications.
Group two is defined by API as “basic stocks have a viscosity index greater than or equal to 80 and less than 120 and have more than 90 percent saturates”. Virgin oils of Group II undergo hydrocracking, which is a more complex procedure than Group I of base oils. During hydrocracking, large hydrocarbon molecules are broken down into smaller ones. As a result of their saturated hydrocarbon molecule structure, these oils have better antioxidation properties. Prices for Group II oils tend to be close to Group I prices.
A group III stock is defined as one containing more than 90 percent saturated, less than 0.03 percent sulfur, and having a viscosity index of at least 120. Compared to Group II oils, a longer process is applied to Group III oils. Hydrocracking is a much more intense process as well. During refinery operations, there is increased pressure and heat. In the end, the resulting oil is purer and of higher quality. Despite being derived from crude oil, Group III oils are sometimes called synthetic hydrocarbons.
Polyalphaolefin base oils comprise Group IV. Polyalphaolefins are small molecules made of uniform compounds, not extracted. In very cold or very hot weather, poly-alpha-olefin (PAO) oils are better suited for use because of their high oxidative stability and low pour points. In addition, PAOs have the advantage of being completely tunable to have properties that can be predicted.
The oils in Group V are any oils other than those described in the previous sections. Any oil that is considered synthetic oil and not considered PAO is counted as a Group V base oil. A few examples of these are naphthenic oils and esters. Most Group V oils are additives to other base oils instead of being used as virgin oil.
Given that it includes all other base oils, this group has the most considerable variation (including polyesters, diesters, polyalkylene glycols, silicones, naphthenic oils, phosphate esters, bio lubes, and more). An oil is categorized as a Group V oil if synthetic and not a polyalphaolefin. Group V oils are frequently utilized in addition to other base oils instead of being used on their own as a base.
All types of base oils do not pose any special toxic hazards under normal use conditions.
However, all lubricants, regardless of type, should be handled carefully, especially to prevent contact with the skin.
Keep away from combustible materials and avoid splashing. Keep items covered and away from potential pollution sources. Don’t pour used oil into drains, waterways, or the soil; properly dispose of it.
You should take the following actions in the event of inhalation, skin and eye contact, and s Ingestion.
Remove the victim from the situation so that you don’t become a casualty. Loosen the remaining clothing and remove any contaminated items. Assume the patient’s most cozy position and maintain warmth. Keep at rest until the patient recovered completely. Consult a doctor if the symptoms continue.
In general, do not cause an allergy with the base oil, if it comes into contact with the skin, wipe it off and then wash the skin with water. Also, seek medical help if there is swelling, redness, blisters or irritation.
If contact occurs, immediately rinse your eyes with water. Visiting a doctor is a reasonable precaution in all instances of eye contamination.
In case of ingestion, rinse the mouth with water and do not try throw up.
Among the products made from base oils are lubricating greases, motor oils, and metal processing fluids. By refining crude oil, base oil is produced. By heating crude oil, distillates separate from each other, and through this way, base oil is produced.
Mineral, vegetable, and synthetic are the three types of base oil. Crude oil is derived from mineral oil, and the refinement process determines its quality.
In order to make base oil, crude oil has to be refined. 42 gallons of crude oil gives approximately 45 gallons of petroleum products, while only 1 percent or about 4 gallons is used for making lubricants. In general, gasoline, diesel fuel, and kerosene-type jet fuel account for the most consumption.
Oils obtained from vacuum resides, and vacuum gas oils are extracted and treated into high-viscosity base oils. Lubes are processed through a variety of units in the lubes plant in order to accomplish this.
