What is the Process of Waste Oil Distillation Plant and Its Advantages?

Waste oil distillation plants play a crucial role in the recycling and refining of waste oil. These plants are capable of refining waste oil, crude oil, as well as tire and plastic pyrolysis oil into diesel. The refined diesel, typically light yellow in color, has a wide range of applications. It can be used in burners, generators, engines, trucks, engineering vehicles, and agricultural machinery vehicles, among others. Compared to pyrolysis oil, refined diesel has a broader usage scope and its price is approximately twice as high.

Applications of refined diesel extracted from waste oil distillation process

In the current market, there are various waste oil distillation plants available. Their processes can basically meet your needs for recycling waste oil. However, the majority of them utilize horizontal reactors, which are modified versions based on pyrolysis plants. These plants usually have large tonnage capacities. For instance, they can load 20 tons of waste oil per batch and rely on fuel heating at the bottom. Due to the large heating area, a significant amount of fuel is required for heating, 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. As a result, the entire process can take around one week. This not only involves a great deal of time and labor but also requires a large area for the plant. Consequently, both the input costs and operating costs increase substantially.

To address these issues and enhance the efficiency of waste oil distillation plants, our company, after years of research and development, has successfully designed a more efficient and environmentally friendly waste oil distillation plant.

Composition of waste oil distillation plant

This advanced plant boasts several remarkable advantages:

Vertical Reactor and Heating Conduction Oil Boiler System: 

By adopting a vertical reactor and equipping it with a heating conduction oil boiler system, this plant saves both time and fuel. Moreover, it enables automatic slagging, streamlining the operation process.

Professional Shell Tube Condensing System: 

The plant features a professional shell tube condensing system with circulating water. This system effectively cools down 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. This innovative approach replaces the traditional acid-base washing processes, 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 mechanism prevents the syngas from flowing back and avoids furnace tempering, ensuring the safety of the operation.

Professional Testing Device: 

Equipped with a professional testing device, this waste oil distillation plant meets national environmental protection standards, making it a reliable and sustainable solution.

Advantages of DOING waste oil distillation plant

What is the Process of DOING Waste Oil Distillation Plant?

Pretreatment

Preheating is used to separate water and ensure that the waste oil reaches the best 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 a temperature of about 250°C. This process separates the water and emulsified oil in the waste oil and prepares it for the subsequent distillation process.

Fractional distillation

DOING new waste oil distillation plant uses a solid catalyst distillation 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. DOING waste oil distillation plant is equipped with a professional shell and tube condensation system to ensure high oil and gas cooling efficiency and an oil product yield of more than 85%.

Recycling and reuse

The refined products, such as diesel and asphalt, can be widely used in industry and transportation. At the same time, the plant is also equipped with an automatic slag discharge system to ensure efficient handling of solid residues.
