Re-refining used lube oil
Sequoia's process technology for re-refining used lubricating oils is based on distillation, adsorption and hydrotreating processes.
Hydrogenation
The design goal is production of Group II or Group III base oil from feedstock such as solvent
neutral (Group 1) base stocks, vacuum gas oils distilled from crude or used oils.
Coolants / Antifreeze Recycling
Sequoia’s process technology for coolant (antifreeze) recycling is based on vacuum distillation. It produces distilled water and > 95% pure glycols from waste coolants.
Waste Fuel / MARPOL Recycling
Sequoia’s equipment for recycling waste fuel oils completely evaporates free as well as emulsified water and also recovers diesel from waste fuel oil.
Transformer oil recycling
Sequoia’s hydrogenation technology almost completely destroys carcinogenic organic chlorine compounds often present in waste transformer oils.
Wastewater Treatment
Disposal of waste water can be costly for many utilities, oil & gas fields, refineries and recyclers.
Global Experience
From 2006, Sequoia has completed projects in various parts of the world including Asia, Australia, South Africa, South America and USA.
