Our used motor oil refining machine has different model and processing capacity, among which our 5ton latest used motor oil refining machine is very favored by our customers. Just take DOING 5TPD latest used motor oil refining machine for an example.

Refining process of used motor oil refining machine

1st-step refining process --used motor oil distillation.

Used motor oil belongs to heavy oil, mainly composed of long-chain hydrocarbon ,which is heavier and has higher density and flash point than diesel fuel. To make it become lighter, its long-chain hydrocarbon has to be cracked down into the short one, so the first step is distillation.

2nd -step refining process --Decoloring and catalytic pyrolysis

In this process, the distillation oil gas will go through the catalytic tower of our used motor oil refining machine for further refining. Two different kinds of catalysts inside the tower work together to purify the distillation oil gas and meanwhile pyrolyze some heaver oil gas.

3rd-step refining process--Distillation oil gas cooling

The distillation oil gas after catalytic treatment will flow into cooling system of our used motor oil refining machine to cooling down and then collected into temporary oil tanks.

4th -step refining process-- Distillation oil further decoloring and purification

This process is optional, but if you wanna use the diesel got from used motor oil for some transportation vehicles, this step is very necessary because it can ensure the final oil is pure and transparent which is good for motors.
