Mineral Waste Oil Recycling Equipment With Vacuum System

Waste oil regeneration/waste oil regeneration system

The waste mineral oil refers to the mineral oil that has been oxidized, polluted by impurities or affected by thermal interaction, and lost its physical and chemical properties so that has to be substituted. There are various types of common waste mineral oil, such as waste internal combustion engine oil, waste motor oil and waste transformer oil, etc.

Our solution will acquire the raw base oil by evaporating severally and then refining the light components like light bio-diesel, and other raw base oil.

The process applies re-purification combined with refining. Firstly, we remove solid
mechanical particles and water from the used oil by physical means, and then we eliminate
light oil from pre-treated lubricating oil by fractionation column. Finally, we apply advanced
molecular distillation technology on high vacuum condition, so that we can obtain
regeneration oil which function is close to natural base oil.

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.
