What is Penetration Bitumen 35/50?

Penetration bitumen 35/50 is a type of bitumen characterized by its penetration value, which measures the depth (in tenths of a millimeter) that a standard needle penetrates the bitumen sample under specific conditions. The penetration range of 35 to 50 indicates the hardness and viscosity of this grade of bitumen, making it suitable for various applications requiring durable and resilient material.

Production Process of Penetration Bitumen 35/50

How is Penetration Bitumen 35/50 Produced? The production of penetration bitumen 35/50 involves several stages, each critical to achieving the desired properties of the final product. Here’s a detailed look at the production process: Crude Oil Selection, Distillation, Vacuum Distillation, Blowing Process, Cooling and Storage

1. Crude Oil Selection: The production begins with the selection of suitable crude oil. Not all crude oils are suitable for producing high-quality bitumen. The selected crude oil should have a high content of asphaltenes and resins, which are essential for the desired properties of bitumen.
2. Distillation: The crude oil undergoes atmospheric distillation, where it is heated and separated into different fractions based on boiling points. The lighter fractions, such as gasoline and diesel, are separated, leaving behind the heavier fractions.
3. Vacuum Distillation: The heavier fractions are then subjected to vacuum distillation. This process further refines the heavy fractions to produce vacuum residue, the primary raw material for bitumen production.
4. Blowing Process: The vacuum residue is processed in an air-blowing unit, where it is heated and blown with air. This process, known as oxidation or blowing, increases the viscosity and modifies the properties of the bitumen. For penetration bitumen 35/50, the blowing process is carefully controlled to achieve the desired penetration value and other specifications.
5. Cooling and Storage: After the blowing process, the bitumen is cooled and stored in heated storage tanks. It is then ready for packaging and transportation.
