Waste oil regeneration/waste oil regeneration system

Waste mineral oil refers to mineral oil that has been oxidized, polluted by impurities or affected by heat, and has lost its physical and chemical properties and must be replaced. There are various types of common waste mineral oils, such as waste internal combustion engine oil, waste engine oil and waste transformer oil.
Our solution will be to obtain feedstock base oils by separately evaporating and then refining light components such as light biodiesel and other feedstock base stocks.
The process adopts the method of combining re-purification and refining. First, we remove the solid
Mechanical particles and water are physically removed from the used oil, then we eliminate
Light oils are extracted from pretreated lubricating oils through a fractionation column. Finally, we apply the advanced
Molecular distillation technology under high vacuum conditions allows us to obtain
Regenerated oils that function close to natural base oils.

Process description
(1) Pretreatment unit
The pretreatment is necessary for most used oil recycle. Firstly, the most water and
mechanical impurities was roughly removed by natural sedimentation for some time at
special temperature, and then we use the centrifugation separator to remove more water

and impurities before the used oil is sent to next unit. If the used oil is very bad, we will use
the flocculation to remove some gum, pitch and reduce the acid value.

(2) Distillation unit
This unit is the core process. Firstly, in order to get good quality base oil, the pretreated
oil is sent to one or two special tower, the odor and light oil is removed by these towers, and
then the oil is sent to flash vessel at high vacuum before short path distillation in order to
remove surplus volatile compound. We normally use two or three short path distillatory to
get several base oil which viscosity degrees is also different, of course, there are different
operating vacuum and temperature in each short path distillatory, we suggest three stage
short path distillatory should better be used in your plant in order to get high product yield at
10,000 TPA throughput capacity.

(3) Clay refining unit
The different base oil form distillation unit is sent dividedly to different decolourization
vessel which is operated at special temperature and vacuum, and some active clay will be
added into vessel depending on the quality of input base oil, after some time, the base oil
with active clay is sent to filtration machine, and then we get the final base oil with good
color and stable quality.
