Pretreatment of Waste Oil

The pretreatment stage is critical for removing large particles and water from the waste oil. Techniques include sedimentation, where gravity separates solids, and centrifugation, which uses centrifugal force to achieve separation.

Heating and Distillation Process

Heating is crucial in waste oil refining, as it facilitates the distillation process. Distillation involves heating the waste oil to high temperatures to separate different fractions. Atmospheric distillation occurs under normal pressure, while vacuum distillation operates under reduced pressure, enabling the separation of components with high boiling points at lower temperatures.

Filtration and Purification

After distillation, filtration systems remove any remaining impurities. Filtration can be achieved through various methods, including mechanical filters, activated carbon filters, and clay treatment. Chemical additives may also be used to enhance purification by neutralizing acidic compounds or breaking down complex molecules.

Advanced Refining Techniques

Modern waste oil refining incorporates advanced technologies to improve efficiency and yield. Membrane technology offers selective filtration, while hydroprocessing uses hydrogen to treat and upgrade the oil. Adsorption methods, employing materials like silica gel, further purify the oil by capturing contaminants.

Efficiency and Yield

The quality of refined oil products, like diesel and gasoline, is an important indicator of equipment technology. Ruike waste oil refining efficiency depends on factors such as the quality of waste oil, the technology used, and operational expertise. Implementing advanced technologies and optimizing processes can significantly increase the yield and quality of refined oil.
