Bitumen extracted from oil or special minerals is called pure bitumen, which is classified according to its formation

Bitumen extracted from oil or special Minerals is called pure bitumen, which is classified according to its formation. Pure Bitumen are also subjected to other industrial processes in order to find the desired properties for different purposes, and we classify different types of bitumen according to the quality of their material in the following order.

Petroleum bitumen
Petroleum bitumen are solid and semi-solid that are obtained directly from the distillation of crude oil or by other additional operations such as blowing air. Residual or heavy oil bitumen is the distillation of crude oil. The amount of crude oil bitumen varies from zero to more than half of it. In addition, bitumen obtained from different sources can have many differences. Therefore, bitumen refineries must carefully choose their crude oil to ensure the quality of bitumen.

Natural bitumen
Bitumen is a natural hydrocarbon resin that has been rediscovered in modern history on the Bonita River in northeastern Utah. This natural asphalt has hardened like a crude oil asphalt. "Natural bitumen, like natural asphalt, is soluble in aliphatic and aromatic solvents." Due to the high compatibility of this product, it is usually used to harden dilute Petroleum derivatives.

Tar bitumen
Types of bitumen Chemically, there are different classifications for bitumen, two of the most common of which are based on the natural or petroleum nature of bitumen and the most common case is based on the type of bitumen supply source, oil or coal or wood.
 

In this article from Nikan west company the gilsonite producer in Iran, we introduce types of Petroleum Bitumen and its Characteristics. In general, bitumen can be divided into two main categories: petroleum bitumen and natural or mineral bitumen. Petroleum bitumen is a bitumen that is produced in a refinery by the distillation of crude oil. The bitumen itself is divided into several important types. Blended bitumen, soluble bitumen, leachate or emulsion and modified bitumen are among these categories. In this two-part article, we examine the characteristics of different types of bitumen . Bitumen production in the refinery has a general approach. The bitumen produced by different processing methods is then converted into petroleum bitumen. At the beginning of this article, we will attempt to describe, in simple terms, the stages of bitumen production and then examine different types. In general, the extracted heavy material consists of two main components: bitumen and lubricating oil. So in the second step, bitumen and oil should be separated. At this stage, the furnace temperature is raised to 400 ° C to separate the bitumen and oil. The main non-volatile material remaining in the distillation tower is the bitumen . In fact, it is used as a feed in the bitumen manufacture with different grades. The bitumen obtained from the vacuum tower can be used in some cases, but most often the properties of the bitumen need to be improved through processes to be applicable in various industries. In this article, we present the types of bitumen made from this bitumen. Blown bitumen is the most popular and widely used type of bitumen. This type of bitumen is used in many cases. Blown bitumen is used as a waterproofing insulator, insulating blocks, asphalt, and roof sealing. Actually, this bitumen has various types that are designed according to ASTM standards and each of them has its own characteristics and properties. The production method of bitumen is relatively simple. The first bitumen was made in 1890 due to the reaction of bitumen heated with oxygen. In the bitumen production, the bitumen is warmed sufficiently, and then the aeration process is initiated by special methods. In this process the bitumen hardens in the air and decreases its sensitivity to heat. It is interesting to know that the same bitumen has different types. Feed type, temperature variables, bitumen viscosity, aeration time, aeration ratio, etc. will all be effective in this regard; and provide bitumen with specific characteristics. In this section, we present the bitumen production method and introduce some blown bitumen. In the next section we will introduce other types of bitumen. Types of petroleum bitumen include blown bitumen, soluble bitumen, leachate and modified bitumen. In the first part, you will be introduced the uses and features of blown bitumen. In the second part of this article we will consider other types of bitumen. In simple terms, dissolved bitumen is obtained by dissolving pure bitumen in solvents or oils. This bitumen is most commonly used in road construction industries and operations for technical and economic reasons. In fact, pure bitumen is all solid and cannot be used in road construction. Soluble bitumen as a special type of petroleum bitumen has different grades and qualities. From the quality of the bitumen used to the type and amount of the solvent, they all affect the final quality of the bitumen. Naturally, the higher the amount of petroleum solvents in pure bitumen, the more fluid the fluid will be. Heating the bitumen and turning it into a liquid at high temperatures is not logical for a variety of reasons. Bitumen decomposition at high temperatures, contamination, need for on-site heating equipment, tightening after cooling, inability to penetrate porous minerals, possible hazards to workers, financial losses from accidents, etc. are all considered as justification to use this type of bitumen as the best choice for asphalt, and road construction. Finally, if bitumen is used in humid environments, it is better to have a certain acidic degree to give a better surface adhesion to wet materials. The bitumen is divided into three groups: premature, slow, and late according to the rate of hardening and the type of solvent. Production of cold asphalt, surface asphalt, single coats, slate coats, and protective coatings for roofs, insulation of roofs and mulching of sand grit are the applications of leachate or bitumen emulsion. Pure bitumen does not have the proper physical and mechanical properties for a variety of reasons. These bitumen have weaknesses in their various functions due to their inherent characteristics. For example, high sensitivity, low tensile strength, low temperature tolerance range, and so on are all examples of pure bitumen. For this reason, bitumen companies for industrial use are always trying to make bitumen a better, more efficient, and durable material by changing the properties of bitumen. The improved bitumen is called modified bitumen.
