The project conforms to the national "dual carbon" strategy and the direction of circular economic development, and has significant environmental benefits and social value, as well as clear economic returns. The project has a reasonable investment structure, low processing cost per ton of oil, a mature operation mode, and a strong market demand for finished products. It is a high-quality physical project with continuous policy support, broad development space, and stable investment returns.

A)Pretreatment system
1.The waste oil to be lifted will enter the coarse filter from the oil inlet valve under the action of the oil pump power, and the impurities 

of large particles will be filtered out and the catalyst after mixing will be sent into the mixing system.
2.In the mixing system, the waste oil acts with the catalyst, long molecular chains in waste oil crack, then form the short molecular 

chains of diesel under the action of  the catalyst.
3.The waste oil of the mixing system enters the distillation system for refining.

B)Water and light oil removal system
Through the heat exchanger heating to the set temperature (controlled by the automatic constant temperature digital display temperature

 controller), and then into the vacuum flash separation chamber, the oil through the atomization injector to make the hot oil burst atomization, 

in the twostage efficient separation tower to form a large expansion area of the oil film, water and gas in the oil in the high vacuum state of 

rapid vaporization to achieve the separation of oil, water and gas; The separated oil is pumped out through the special oil pump, sent to the

 turnover tank, and enters the next process. The water and light oil in the raw oil liquid are condensed by the condenser and enter the oil-water 

separation tank. Under the control of the oil-water interface instrument, the separation of light oil and water is realized, the water enters the 

collection tank, and the light oil enters the light oil tank.

C)Distillation and purification separation system
Under the action of oil pump and negative pressure, the oil in the rectification system enters the heat exchanger through the flow transmitter (regulating

 the flow rate). The oil after heat transfer enters the separation tower, and the hot oil is atomized by the atomizer. After the oil and gas on the top of the 

tower is condensed by the condenser, the diesel begins to be purified. As the temperature changes, the precision of the diesel will gradually increase, 

and the system will collect the finished oil according to the changes of the oil. The unatomized oil at the injector drops and flows into the reboiler for 

secondary heating and gasification. The residue is controlled by the level gauge and is continuously exported through the condenser

D)Refine the system
In the process of vacuum distillation, the diesel product contains a small part of gum, asphaltene, polycyclic short side chain hydrocarbons and

other waste oil con taining sulfur, nitrogen, oxygen compounds and other nonideal components. TThe sulfur in diesel generates sulfide, which 

will corrode the engine, make the engine rust, shorten the service life, pollute the environment. Therefore, the non-ideal components must be 

removed by refining method in order to make the sulfur content,anti-oxidation stability, residual carbon value and color of diesel meet the

 requirements of product quality standards.

E)Exhaust gas backfiring system
In the process of waste oil regeneration, some non-condensing gas will be produced, and if these non-condensing gas is not recycled and 

discharged into the atmosphere, it will inevitably cause pollution. The exhaust gas back combustion system effectively solves this problem.

The exhaust gas passes through the three safety devices of water seal and flame arrester combustion nozzle. On the one hand, it can prevent 

air pollution, on the other hand, it can save a lot of fuel and save energy.

F)Exhaust gas treatment system
The design of wet dust removal system,activated carbon adsorption +UV photolysis, dust removal rate of more than 95%, completely solved the

 problem of black smoke, not environmental protection, dust removal by wet dust collector to reach the standard discharge, because of the use 

of induced draft fan device, so the smoke exhaust system does not hold pressure operation safety, smoke emission can meet the relevant standards

of air pollutant comprehensive discharge standards

G)Decompression system
The vacuum pressure system is a vacuum unit composed of water ring pump + two stage booster pump, which mainly provides a high vacuum 

environment for the whole equipment, reduces the boiling point of the product, and obtains higher quality base oil at a lower temperature.

H)Waste disposal 
Oily waste residue belongs to dangerous waste, and there are 2 treatment methods
1.Send to the hazardous waste recycling company,
2.sold to asphalt factory deep processing for building materials, or paving, can also be sold to burning coal when burning oil

1. Overview of diesel distillation plant

Waste oil regeneration diesel equipment converts waste oily substances into usable diesel fuel through physical, chemical,  processes.

The process includes waste oil collection, pretreatment, catalytic conversion, and purification. Ultimately, waste oil is transformed into

regenerated diesel fuel, achieving resource reuse and environmental protection.

2. Working Principle of waste oil to diesel equipment

The waste oil regeneration diesel equipment operates on complex catalytic conversion technology. Initially, collected waste oil undergoes

pretreatment, including filtration, dehydration, and impurity removal, to eliminate solid impurities and harmful substances. The pretreated

oil is then processed in a reactor under specific temperature, pressure, and catalyst conditions, leading to chemical reactions like cracking

and hydrodesulfurization, resulting in a pure hydrocarbon mixture. Finally, this mixture is refined through rectification and separation to

produce regenerated diesel fuel that meets standards.

3. Advantages of waste oil to diesel Refinery Plant

①Continuous production  improve 50% utilization；②Eliminate coking&maintain  100% thermal effciency；③Better oil color and 2% higher

recovery rate；④Extend equipment lifespan >l0 Year.

4. Technological Challenges and Development Trends of diesel oil distillation plant

Waste oil regeneration diesel equipment has advantages but faces challenges in technological development. The complex composition of waste

oil necessitates varied processing technologies and catalysts, raising equipment complexity and costs. Additionally, ensuring the quality stability

and long-term safety of regenerated diesel fuel remains a concern.

In summary, the fact that the diesel refinery machines can regenerate diesel fuel to meet the Euro IV standard is a significant technological

achievement. It helps reduce environmental pollution, promotes sustainable development, and demonstrates the equipment's leading position

in diesel regeneration technology.
