Atmospheric Vacuum Distillation Plant for Waste Engine Oil
The system specializes in recycling waste lubricants (e.g., engine oil, gear oil) through low-temperature catalytic pyrolysis. Operating at atmospheric pressure, it achieves 80-85% base oil recovery with multi-stage distillation and advanced decolorization. Equipped with automation control, gas recycling, and CE-certified safety systems, it ensures energy-efficient, continuous production of high-quality base oil. Ideal for automotive and industrial waste oil regeneration.

Multi-stage distillation, high recovery rate
The multi-stage distillation tower structure is adopted to separate light and heavy components through precise temperature control, so as to achieve a base oil recovery rate of up to 80-85%.
Atmospheric and vacuum synergy, lower heat loss
The atmospheric section initially removes light impurities, and the vacuum section low-temperature fractionates the main components under negative pressure to avoid high-temperature cracking, extend the life of the equipment, and ensure the quality of the base oil.
Low-temperature catalytic cracking technology
The catalyst system is introduced to effectively destroy the molecular chain structure of impurities, improve the oil yield and purification degree, and reduce the residual harmful elements such as sulfur and chlorine.
Through PLC intelligent control, real-time adjustment and monitoring of temperature, pressure, liquid level, etc. are realized, which makes the operation safer, the production line smarter, and supports remote control and data recording.
The by-product combustible gas can be used for heating devices after separation, saving about 30%-40% of fuel costs; the tail gas is discharged after being treated by condensation and purification devices, which meet the CE environmental protection standards.
