Oil Treatment Technology

Oil Treatment Technology

Enviroflex develops and supplies advanced oil treatment technologies for the used oil treatment and used lubricant Re-refinery as well as for purification, regeneration, upgrading, and recycling of industrial oils and lubricants. Our systems are designed to treat both used oils and virgin base oils, enabling the recovery of valuable hydrocarbons, improvement of oil quality, and production of high-performance lubricant products.

With strong expertise in separation technology, vacuum processing, adsorption, filtration, and refining processes, Enviroflex provides integrated solutions covering the entire oil treatment chain — from used oil re-refining and base oil upgrading to purification, regeneration, and lubricant blending.

Our technologies are widely used in used oil recycling plants, lubricant manufacturing facilities, transformer maintenance services, and industrial oil recovery systems, supporting the transition toward a more sustainable circular economy for lubricants and hydrocarbons.

The main technology platforms offered by Enviroflex include:

• ReLubeX – Used Oil Re-Refining Systems
• POLISHLUBE – Base Oil Polishing and Finishing Plants
• RePureX – Vacuum Oil Purification Systems
• ReGenX – Oil Regeneration Plants
• TURBOSORB – Advanced Adsorptive Oil Treatment Technology
• ReBlendX – Lubricant Blending Systems

These technologies can operate as stand-alone treatment units or integrated processing systems, depending on the required product quality and processing capacity.

Used Oil Re-Refining – ReLubeX

ReLubeX systems are designed for the re-refining of used lubricating oils, enabling the recovery of valuable hydrocarbon products such as distilled fuels and base oil fractions.

The process typically includes pretreatment, thermal processing, and vacuum distillation, allowing efficient separation of contaminants and recovery of reusable oil fractions from waste lubricants.

Typical feedstocks include:

• Used engine oils
• Industrial lubricating oils
• Hydraulic oils
• Mixed waste lubricants

Recovered oil fractions can subsequently be upgraded using POLISHLUBE finishing systems or further purification technologies, enabling the production of recycled base oils suitable for lubricant blending or industrial applications.

Base Oil Polishing and Finishing– POLISHLUBE

POLISHLUBE plants are designed for the polishing, finishing, and upgrading of base oils and hydrocarbon streams. Using advanced adsorptive treatment and filtration technology, these systems remove trace impurities that affect oil color, stability, and chemical purity.

POLISHLUBE systems can treat both recycled base oils and virgin base oils, enabling producers to upgrade lower-quality oils into higher-value products.

Typical applications include:

• Polishing of base oils obtained from used oil re-refining
• Upgrading of lower-quality or off-spec base oils
• Treatment of distilled black lube oil streams
• Diesel and distillate fuel treatment
• Paraffin wax decolorization
• Thermal oil regeneration and purification
• Hydraulic oil purification and upgrading
• Industrial oil treatment

By removing oxidation products, sulfur compounds, color bodies, and polar contaminants, POLISHLUBE systems significantly improve oil quality, product stability, and commercial value.

Vacuum Oil Purification – RePureX

RePureX systems are designed for vacuum purification of insulating and industrial oils, effectively removing moisture, dissolved gases, free gases, and particulate contamination.

The systems combine vacuum degassing, controlled heating, and multi-stage filtration, restoring essential oil properties and extending oil service life.

RePureX units are available as mobile transformer oil purification plants or stationary oil purification systems, commonly used for:

• Transformer oil purification
• Insulating oil dehydration and degassing
• Turbine oil purification
• Hydraulic oil purification
• Industrial oil maintenance

Vacuum purification improves dielectric strength, moisture content, and oil cleanliness, ensuring reliable operation of oil-filled electrical equipment.

Oil Regeneration Systems – ReGenX

For oils that have undergone significant chemical degradation, Enviroflex supplies ReGenX oil regeneration plants. These systems combine purification with adsorptive regeneration technology to remove oxidation by-products and acidic compounds that cannot be removed by filtration alone.

ReGenX systems are particularly suitable for:

• Regeneration of aged transformer oil
• Hydraulic oil regeneration
• Industrial oil recovery
• Restoration of oxidized lubricants

The regeneration process removes acids, oxidation products, sludge precursors, and polar contaminants, restoring oil properties and extending the useful life of valuable oils.

Advanced Adsorptive Oil Treatment – TURBOSORB

TURBOSORB is Enviroflex’s advanced adsorptive oil purification technology, based on specially selected and reactivable adsorbent materials.

The technology removes polar contaminants, sulfur compounds, metals, oxidation products, and color bodies from oil streams, significantly improving oil purity and chemical stability.

TURBOSORB can be applied in several oil treatment processes, including:

• Base oil finishing and upgrading
• Transformer oil regeneration
• Post-distillation oil purification
• Industrial oil purification

This technology enhances oil quality while maintaining efficient adsorbent regeneration and long operational life.

Lubricant Blending Systems – ReBlendX

ReBlendX systems are designed for the production of finished lubricants through controlled blending of base oils and additive packages.

These systems allow manufacturers to produce a wide range of lubricant products, including:

• Automotive engine oils
• Hydraulic oils
• Industrial lubricants
• Gear oils
• Specialty lubricant formulations

ReBlendX blending plants ensure accurate formulation control, homogeneous mixing, and flexible production capacity.
