What are Waste Oil Recycling Machines?

Waste Mineral Oil Recycling and Advanced Refining Systems

HK Makine | Engineering Solutions for Europe, Asia, and the Entire World

Global Export and Technical Service Network

As HK Makine, we export our waste mineral oil regeneration technologies worldwide, primarily to Europe and Asia markets. From Germany to Central Asia, we establish turnkey mineral oil refineries, provide technical personnel training, and offer long-term spare parts support.

Advanced Purification with Clay, Bentonite, and Acid Neutralization

Special processes we apply to transform waste oil from raw material into high-quality base oil:

Acid Neutralization: Chemical stabilization to remove acidic components formed by oil oxidation and establish pH balance.
Clay and Bentonite Activation: Active clays applied under controlled temperature in special reactors clarify the oil color and trap heavy metals and unwanted odors.
High-Pressure Filtration: Post-reaction oil is completely purified from clay and residue through filter press units to obtain clear, odorless SN 150 - SN 500 base oil.

Sectoral Questions and Technical Answers (FAQ)

Question: Why is coal not used in your plants?
Answer: Coal makes it impossible to keep the heat constant. To treat mineral oil without damaging its structure, we use thermal oil heating systems with precision digital control.

Question: Do you build biodiesel plants?
Answer: No. As HK Makine, we specialize exclusively in waste mineral oil purification and recycling systems.

Question: Are your systems suitable for container shipping?
Answer: Yes, all our vertical tanks and reactor units are manufactured in a modular structure suitable for international logistics standards.

Question: Is the clay and bentonite process mandatory?
Answer: This stage is engineering-wise essential to capture standard base oil quality, clarify the oil color, and remove odors.
