Column type furfural treatment used oil re-refining plant

Traditional column type vacuum distillation
with furfural rectification

Column type vacuum distillation is similar
like the crude oil distillation towers, oil is re-refined through atmospheric
distillation and vacuum distillation column. It is easy to understand. Only
thing is the inner structure of packaged distillation column is slightly
different from the crude oil distillation column to suit the used lube oil with
high content of colloid, additives, organic acid. The distilled raw base oil
will be sent to rectification unit to have the oil rectified by furfural
extraction. The investment of this kind of process is generally high, so it is suitable
for larger scale oil re-refineries.

Advantages of column type used oil
re-refining process.

1.      
Suitable for high scale project
higher than 100kt/a.

2.      
The recycled base oil quality
through furfural treatment is very good.

3.      
Continuous operating with DCS automatic control.
