Hydraulic Oil Recycling

Both used engine oil and hydraulic oil are hydrocarbon-based lubricants whose long-chain molecules closely resemble those in diesel fuel, and hydraulic oil recycling can recover that value cleanly. After use, the oils are contaminated but their base structure still holds real fuel potential.

Why These Oils Suit Diesel Recovery

Engine oil carries soot, coolant residue, and metal particles, while hydraulic oil tends to accumulate fewer additives and less ash. That difference matters: cleaner, lower-ash hydraulic oil generally converts more readily into a lighter, clearer diesel fraction than heavily contaminated engine oil.

The Four-Stage Conversion Process

Recovery starts with pre-treatment and dehydration to remove water, solids, and antifreeze. Vacuum distillation then vaporises and condenses light and middle distillates, catalytic upgrading improves colour, sulfur, and cetane, and final polishing and filtration deliver a stable, ready-to-use fuel.

Diesel Quality by Feedstock

Hydraulic oil typically yields a cleaner, lighter diesel with lower ash, while engine oil requires more refining but still produces fuel suitable for off-road, generator, and industrial use. With proper desulfurization and treatment, output can meet recognised diesel specifications for many applications.

Why Recycle Into Diesel

Turning these oils into fuel cuts dependence on crude, lowers waste-management costs, and creates a marketable product that supports circular-economy goals while reducing the carbon footprint of industrial operations compared to incineration or dumping.

Convert Mixed Waste Oils Into Clean Diesel

Engine, hydraulic, and transmission oils can be processed together into a stable, saleable fuel.

Klean Industries builds systems that handle mixed feedstocks with high recovery and clean output.
