Features
Chemical demetallization pre-treatment unit:
The Used Oil Refining Plant is equipped with dedicated demetallization reaction tanks. It removes metal salts and oxidized sediments in waste oil through chemical chelating-precipitation, reduces corrosion and coking of the rectification unit caused by metal ions, and protects rectification columns and heat-exchange equipment.
Graded vacuum rectification process system:
Multi-stage vacuum rectification separates light oil, base-oil fractions and heavy-duty residues section-by-section. It accurately cuts base-oil components of different viscosities and realizes separate collection of various-grade base-oil products.
Residue reduction treatment module:
Asphalt residues generated by rectification in the Used Oil Refining Plant can be further concentrated for volume reduction. Residue output is decreased, the total amount of hazardous solid-waste disposal is cut down, and customers' hazardous-waste disposal costs are lowered.
Full-process closed negative-pressure explosion-proof architecture:
The whole system of the Used Oil Refining Plant runs under closed negative pressure. Multiple interlocks for oxygen-content, combustible-gas, temperature and pressure are configured to inhibit oil oxidation, prevent oil-gas leakage and satisfy safety specifications for hazardous-waste processing.
Advantage
Deep removal of metallic impurities:
With the front-end demetallization process, the Used Oil Refining Plant solves the pain point of column coking and corrosion caused by high metal content in waste lubricating oil, and extends the continuous-operation cycle of the unit.
Controllable viscosity of base-oil products:
Rectification cuts base oil of different viscosities in sections. Multiple grades of base-oil products can be produced, broadening product sales channels and improving project economic benefits.
Wide raw-material adaptability:
The Used Oil Refining Plant can process various waste mineral oil including mixed used engine oil, hydraulic oil and gear oil, featuring strong compatibility for recycled waste oil from mixed sources.
High automation and low labor cost:
Automatic control for feeding, chemical dosing and fraction collection reduces on-site manpower input and lowers production risks caused by human operational errors.
Application Scenarios
- Recycling and regeneration of used engine oil: Process waste engine oil drained from various vehicles and mechanical equipment to regenerate lubricant base oil.
- Regeneration of waste hydraulic oil and gear oil: The Used Oil Refining Plant purifies and regenerates waste hydraulic oil and gear oil from industrial equipment to obtain qualified base-oil feedstock.
- Projects for waste-oil recycling & disposal enterprises: Realize resource regeneration for recycled mixed waste mineral oil to turn waste into valuables.
- On-site treatment of waste oil in industrial and mining enterprises: Refine and regenerate large volumes of waste lubricating oil generated inside large mines and factories locally, reducing hazardous-waste transportation costs.
- New-construction and technical-revamping of small-and-medium-sized waste-oil regeneration plants: Build new waste-oil regeneration production lines, or upgrade existing batch-type waste-oil processing equipment.
Packing & Shipping
- Pressure-vessel components including demetallization reactor, vacuum rectification column, heat exchanger and residue concentration tank are treated with sandblasting for anti-corrosion. Protective cover plates are installed for all nozzles and flanges. Large-size column sections are fabricated in segments, bare-packed and fixed on transport cradles with limit anti-collision reinforcement.
- Column internals, sealing gaskets, filter cartridges, special chemical-dosing assemblies, valves, pipe fittings and special tools are packed by category. Each package is attached with a material list for checking and verification upon port arrival.
- All equipment components are split in compliance with 40HQ container standards. Over-size heavy-duty components adopt break-bulk sea-freight. Packing lists and loading guidance are provided, and on-site supervision of loading by customers is supported.
FAQ
Q1: What raw materials can this used oil refining plant mainly process?
A: It mainly processes various waste mineral lubricating oil such as used engine oil, hydraulic oil and gear oil. Direct processing of high content pyrolysis oil is not recommended; please select pyrolysis oil refining equipment for pyrolysis oil.
Q2: What grade of base oil can be produced?
A: Regenerated base oil is obtained after demetallization and vacuum rectification. To reach higher national standard base oil requirements, subsequent clay refining or hydro refining units shall be equipped.
Q3: What is the approximate continuous operation cycle of the plant?
A: On the premise of qualified pre treated feedstock, it can run continuously for 20 35 days before shutdown maintenance. The front end demetallization unit effectively reduces contamination of the rectification system from metallic impurities.
Q4: What impact will excessive moisture in waste oil exert on the equipment?
A: Raw materials shall be dehydrated in advance. Excessive moisture will undermine system vacuum degree and affect rectification performance. We can provide supporting pre treatment solutions for raw material dehydration.
Q5: What is the daily processing capacity range of the equipment?
A: The daily throughput of standard models ranges from 5 45 tons. Non standard customization is supported, and capacity can be matched according to customers' waste oil recycling volume.
