The Importance of Waste Oil Purification Machines

Engineering Excellence Since 2025

Vacuum Waste Oil Recycling Plants

HK Makine offers turnkey refining systems that decompose waste engine and industrial oils at the molecular level to produce high-purity base oil (SN 150 - SN 500) in compliance with API standards.

Refining Technologies

1. Neutralization System: Stabilization of acidic components and oxidation products in waste oil using chemical reagents. This process eliminates corrosive properties and optimizes pH balance.

2. Advanced Acid & Clay Filtration: The most reliable refining method. Polymeric wastes are precipitated with sulfuric acid; then color, odor, and microscopic impurities are adsorbed using active clay (Bleaching Earth).

Important Notice: Since temperature control is vital in our systems, the use of coal is strictly not recommended. Only digitally controlled resistances or thermal oil systems are integrated.

Innovative Solvent Extraction

This method separates unwanted aromatics and heavy metals from the oil using special solvents without damaging the chemical structure. It is eco-friendly, reduces sludge waste by 90%, and preserves the viscosity index of the base oil.

Vacuum Power & Capacity

- Operation: -0.1 MPa High Vacuum
- Model: HK-ATK 5 (5.000 Liters / 12 Hours)
- Compatibility: Vertical tanks and cooling towers.

Technical Output and Efficiency Matrix

Product Category Yield Rate Flash Point Application Area
SN 150 / SN 350 Base Oil 70% - 75% 215°C - 238°C Lube oil blending, hydraulic and industrial oils.
Light Distillate (Thin Oil) 10% - 15% 60°C - 85°C Industrial fuel, mold oil, and protective oils.
Bitumen & Heavy Residue 5% - 8% > 270°C Insulation, asphalt additive, and industrial paint raw material.

Frequently Asked Questions (FAQ)

Can diesel (fuel) be obtained from waste oil?

Diesel production from waste oil is possible; however, as HK Makine, we recommend Base Oil production, which has a higher economic value. Our systems produce pure raw materials without disrupting the chemical chain of the oil.

How long does plant installation take and do you ship worldwide?

Manufacturing of our HK-ATK series plants takes place in Gaziantep. We provide turnkey installation and personnel training worldwide, including Algeria, Afghanistan, and Europe, within 45-60 days.

Is recycled oil as high quality as original oil?

Yes. Oil passing through vacuum distillation and neutralization processes is completely purified from metal and carbon waste. When correct additives are added, it provides original oil performance at API standards.
