PyrolysisUnit Waste Oil Distillation Machine is an eco-friendly resource recovery equipment that can process up to 20t of waste engine oil, waste lubricating oil, waste hydraulic oil, waste plastic oil, and waste tire oil within 24h for refining and purification.
Its core principle relies on high-temperature distillation and fractional distillation processes to remove impurities, moisture, heavy metals, and unstable components from waste oil, converting it into clean, reusable fuel oil or base oil.
Features of Waste oil distillation Machine>>
Distillation plants incorporates a pre-treatment device that dehydrates and removes impurities from the waste oil, significantly improving the efficiency of subsequent distillation and the quality of the finished oil. A single unit of equipment can process 8-20 tons of waste oil per day, generating a corresponding daily output of 7-18 tons of finished oil, with an oil yield rate stable between 80% and 90%.
A single distillation machine requires only 2-3 operators to complete the entire production process. The machine’s intelligent fault diagnosis system monitors operating status in real time. Through condensation, adsorption and other processes, the waste gas removal rate is increased to more than 98%, and the emission indicators are far lower than the relevant national standards.

What is Waste oil distillation Machine
A Waste Oil Distillation Machine is an advanced refining system designed to convert crude pyrolysis oil or waste oils—such as waste engine oil, lubricating oil, hydraulic oil, tire oil, and plastic oil—into high-quality, reusable fuel oil or diesel.
Unlike traditional low-efficiency batch furnaces, modern distillation machines integrate the strengths of petrochemical refining with cost-effective, practical designs. They operate under atmospheric distillation processes, where crude oil is pumped into a distillation reactor, heated, and separated into oil vapor. The vapors are then condensed into clean fuel oil, while non-condensable gases are recycled as energy through a specialized combustion system.
Key Features
High Oil Yield: Pure crude oil recovery rate of 80% or above.
Environmental Protection: Equipped with gas burners, dust-removal systems, and closed-loop water circulation for emission control.
Energy Efficiency: Non-condensable gases (methane to butane) are reused in the heating system, significantly reducing external fuel consumption.
Safety & Automation: Centralized electric control, heat-exchange technology, and pressure-reduction operation ensure stable and secure production.
Wide Feedstock Compatibility: Can process crude pyrolysis oil from waste plastics/rubbers, waste lubricants, waste crude oil, and cleaning oils.
Applications
The refined fuel oil or diesel can be used in:
Industrial boilers and furnaces
Transportation sector (after meeting diesel standards such as 0# or -10#)
Chemical industry as raw materials
By replacing outdated “soil furnace” methods, waste oil distillation machines provide an eco-friendly, efficient, and safe solution for the waste-to-fuel industry, helping reduce environmental pollution while creating higher economic value.
Core Components of Pyrolysis oil Distillation Plant
Distillation Reactor
Acts as the primary heating chamber where crude pyrolysis oil is heated and vaporized. Initiates the separation of oil fractions through controlled thermal processing under atmospheric or slight vacuum conditions. Designed to handle high temperatures with robust insulation to ensure safety and efficiency.
Buffer Tank
Temporarily stores separated oil vapors and stabilizes the pressure within the system. Prevents backflow and ensures smooth, continuous vapor delivery to the condenser. Acts as a safety buffer during pressure fluctuations or sudden feed interruptions.
Condensation System
Rapidly cools oil vapors into liquid form (diesel, gasoline, etc.) through efficient heat exchange. Usually consists of multiple condensers (e.g., shell-and-tube or coil type) to maximize condensation efficiency. Directly influences the final oil yield and recovery rate.
Fractionating Tower
Performs fractional separation of vaporized oil based on boiling points. Ensures higher purity output by allowing light and heavy oil vapors to condense at different levels. Enhances product quality through multi-stage temperature stratification.
Non-condensable Gas Recycling System
Captures and recycles non-condensable gases (e.g., methane, ethane, propane). These gases are reused as fuel for the heating system, forming a closed-loop energy cycle. Helps reduce external fuel costs and minimizes emissions.
Flue Gas Heating System / Exhaust Gas Treatment Unit
Burns recycled gases and provides thermal energy to heat the distillation reactor. Integrated with safety features like gas burners, flame arrestors, and backfire prevention. Includes systems for neutralizing or capturing harmful exhaust, ensuring compliance with emission standards.
Smoke Dust Removal System
Treats flue gases before atmospheric discharge to remove particulates, smoke, and acidic gases. Typically uses dual-stage water scrubbers or cyclone dust collectors. Ensures the plant complies with national and international environmental regulations.

Chapter 1: Introduction to Waste Oil Distillation
1.Early Waste Oil Treatment Methods
In the early stages of waste oil management, treatment methods were often rudimentary and inefficient. The most common practices included landfilling, direct burning, and crude batch furnaces (“soil furnaces”).
Landfilling and Dumping: Waste oil was frequently discarded in landfills or directly into the environment, leading to serious soil and water contamination.
Incineration and Direct Burning: Some facilities burned waste oil as a fuel without proper emission controls, producing heavy smoke, toxic gases, and harmful particulates.
Primitive Distillation Furnaces: Small, manually operated horizontal batch furnaces were used in certain regions. These furnaces relied on coal or wood for heating, had long processing cycles, low yields, and posed significant risks in terms of safety and pollution.
While these early methods provided a way to handle waste oil, they caused low oil recovery rates, high environmental pollution, and un. These shortcomings paved the way for the development of modern waste oil distillation machi, which

Chapter 4: How Waste Oil Distillation Works
Waste oil distillation is an efficient process that converts used or contaminated oils into clean, reusable base oils. The process begins with pre-treatment, where waste oil is filtered to remove debris and dehydrated to eliminate water. In some cases, acid washing is applied to neutralize acids and reduce heavy metals. The oil is then gradually heated in a distillation chamber, allowing different hydrocarbon components to evaporate at their specific temperatures. Vaporized oil passes through a condenser, cooling back into liquid form, while heavy residues like sludge remain in the bottom for disposal or further processing. Finally, the distilled oil may undergo additional filtration or vacuum treatment to ensure purity, producing high-quality base oil suitable for industrial use, blending, or fuel. This method not only recovers valuable oil but also minimizes environmental pollution, providing a sustainable solution for managing waste oil.
