  Principle introduction of waste lubricating oil
 
In recent years, the waste oil regeneration process has been divided into three types internationally:
Type I pickling: this process has been eliminated because it causes great environmental pollution and the quality of the treated basic oil is poor

Type II   Flocculation and filtration are roughly equivalent to simple regeneration in the past classification
The main purpose is to remove water, general suspended mechanical impurities and mechanical impurities stably dispersed in colloidal state from the waste oil
Chemical reagents such as water glass and tetraethylene pentamine will be added
After the impurities are dehydrated, a large amount of clay not less than 25% will be added for decolorization
This kind of process has high chemical treatment cost, low recovery rate and great environmental pollution

  The third type of vacuum distillation is a regeneration process including distillation, which produces regenerated base oil that meets the quality requirements of natural oil base oil, and prepares various low, medium and high-grade oil products with similar quality to those produced from natural oil

  Our company Chongqing Yangjiang waste lubricating oil mineral oil vacuum distillation regeneration refining base oil equipment technology
Ty series used engine oil regeneration treatment system can regenerate and restore almost all used lubricating oil into base oil by using the process of vacuum distillation
This system has the characteristics of low cost, recovery rate higher than 85% and environmental protection

  Vacuum distillation is the core waste oil regeneration technology
Ty waste oil regeneration and reduction system adopts batch treatment
The pretreated waste oil (through natural sedimentation, or centrifuge to remove water and impurities) is pumped into the catalyst reaction tank for full mixing and reaction, and the fully reflected waste oil is pumped into the distillation kettle to allow the waste oil to be heated under vacuum
With the increase of temperature, the oil and gas of different components will evaporate
After cooling, the corresponding fuel oil, light base oil and heavy base oil can be obtained

Process description of Chongqing Yangjiang waste lubricating oil mineral oil vacuum distillation regeneration refining base oil equipment
 
  1
Firstly, the waste lubricating oil pump after natural sedimentation is put into the reactor, and the aqueous solutions of two catalysts are added
The waste lubricating oil is stirred in the reactor for a certain time and kept still
We are separating the impurities and part of the colloid under the reactor
The oil pretreated by this chemical catalyst will not produce obvious cracking even if the waste oil is heated to 400 ℃ under normal pressure
(under normal pressure, the waste oil without pretreatment starts cracking at 300 ℃, so the quality of the recovered base oil and the recovery rate are significantly reduced
)

The pretreated waste oil is heated in the distillation reactor
The temperature of the waste oil is controlled within 350 ° C in the heating furnace, distilled in the distillation reactor (the vacuum in the distillation reactor is controlled under the absolute pressure within 800pa), and the distilled oil and gas are cut on the cooler (according to the temperature of the distilled waste oil)
Gasoline, diesel, light base oil, heavy base oil, etc
can be obtained, The obtained gasoline and diesel oil are water white and the base oil is light yellow

When the temperature reaches 55 ℃, the diesel components in the waste engine oil begin to be distilled out; When the temperature of the used engine oil is between 110-170, the diesel components in the used engine oil are distilled out; When the temperature is between 170-260 ℃, the distilled treated oil is light base oil
When the temperature is between 260-350 ℃, the collected oil is heavy base oil

During the whole distillation process, the impurities in the final distillation reactor are pumped out by the high-temperature slag pump, and these oil slurries can be used as asphalt and heavy fuel oil

3 heating raw materials can be electricity, diesel, coal, fuel oil, natural gas, etc
