How Does a Waste Oil Refining Machine Operate and What Are Its Benefits?

 

 

DOING waste oil distillation machine

Waste oil refining machines are pivotal in recycling and refining waste oil. They can convert waste oil, crude oil, and even pyrolysis oil from tires and plastics into diesel. This refined diesel, typically light yellow, is versatile and can be used in burners, generators, engines, trucks, engineering vehicles, agricultural machinery, and more. Compared to pyrolysis oil, refined diesel has a broader application scope and is priced about twice as high.

Applications of refined diesel extracted from waste oil distillation process

Nowadays, various waste oil refining machines are available in the market. Most of them use horizontal reactors, which are modified from pyrolysis machines and have large tonnage capacities. For example, they can process 20 tons of waste oil per batch and rely on bottom fuel heating. Due to the large heating area, a significant amount of fuel is required, and the heating process is time-consuming, often taking 3 to 4 days. Additionally, it takes about 1 day for cooling down and 1 to 2 days for slag discharge, resulting in an entire process of around one week. This not only involves substantial time and labor but also requires a large machine area, leading to increased input and operating costs.

 

To address these issues and enhance the efficiency of waste oil refining machines, our company has successfully designed a more efficient and eco-friendly waste oil refining machine after years of research and development. 

DOING waste oil refining machine types

 

This advanced machine offers several notable advantages:

 

Vertical Reactor and Heating Conduction Oil Boiler System: By adopting a vertical reactor and equipping it with a heating conduction oil boiler system, the machine saves time and fuel. It also enables automatic slagging, simplifying the operation process.

Professional Shell Tube Condensing System: The machine features a professional shell tube condensing system with circulating water. This effectively cools the oil gas, ensuring an oil yield of over 85%.

Catalyst Process: It employs a catalyst process to catalytically crack heavy oil fractions into light oil fractions, replacing traditional acid-base washing processes and significantly improving production efficiency.

Safety Device: A water seal device is installed as a safety measure. The syngas passes through the water seal device and then burns to heat the reactor via the gas nozzle. This prevents syngas backflow and avoids furnace tempering, ensuring operational safety.

    Professional Testing Device: Equipped with a professional testing device, the machine meets national environmental protection standards, making it a reliable and sustainable solution.

Process of DOING Waste Oil Refining Machine:

    Pretreatment: Preheating is used to separate water and ensure that the waste oil reaches the optimal state before entering the refining stage.

    Heating and Evaporation: The pretreated waste oil is sent to the vertical reactor and preheated with heat transfer oil, usually to around 250°C. This process separates water and emulsified oil in the waste oil and prepares it for the subsequent refining process.

Fractional Refining: The DOING new waste oil refining machine uses a solid catalyst refining process. In this stage, the waste oil is heated to 300°C to 450°C and fractionated under vacuum conditions. By controlling the temperature and pressure, light components (such as oil and gas) are separated, while heavy components are further processed.

Condensation and Collection: The fractionated oil and gas are cooled and liquefied by an efficient condensation system. The DOING waste oil refining machine is equipped with a professional shell and tube condensation system to ensure high oil and gas cooling efficiency and an oil product yield of over 85%.

    Recycling and Reuse: The refined products, such as diesel and asphalt, can be widely used in industry and transportation. Meanwhile, the machine is also equipped with an automatic slag discharge system to ensure efficient handling of solid residues.
