Features
Special pre-treatment sedimentation unit for pyrolysis oil:
The physical refining plant is equipped with a combined module of multi-stage buffer sedimentation and pre-filtration. Targeting the material characteristics of pyrolysis crude oil containing carbon powder and fine coke residues, it removes solid carbon-slag impurities step-by-step, prevents carbon powder from entering the subsequent rectification unit, protects tower internals and heat-exchange equipment, and reduces clogging risks.
Negative-pressure molecular distillation refining system:
The physical refining plant adopts molecular distillation technology to cut components of pre-treated pyrolysis crude oil under high-vacuum and low-temperature conditions. Different fractions are separated based on differences in the mean free path of molecules. Materials are exposed to heat for an extremely short time, inhibiting secondary cracking and coking of pyrolysis oil and guaranteeing the quality of distillate oil.
Closed oil-gas recovery and tail-gas purification unit:
The whole process operates under negative-pressure closed conditions. Volatile oil-gas generated in all working procedures is collected uniformly and sent to the tail-gas purification system for treatment. Fugitive oil-gas escape is eliminated, pungent odors are reduced, and workshop environmental-protection emission requirements are satisfied.
Advantage
Targeted adaptation to working conditions of pyrolysis crude oil:
Designed for the unique material features of pyrolysis oil with high carbon-powder content, heavy gums and high sulfur content. Different from ordinary waste-oil refining equipment, it boasts stronger anti-interference capability against impurities, lowers clogging risks of towers and heat exchangers, and is suitable for supporting pyrolysis production lines.
Low-temperature molecular distillation to reduce oil loss:
The short-path heating mode avoids high-temperature cracking of large-molecule base-oil components, effectively increases the yield of target distillate oil and improves the overall economic benefits of the project.
Flexible process combination for modular capacity expansion:
The physical refining plant can be directly connected to continuous pyrolysis equipment for continuous feed-in processing, or intermittently process pyrolysis crude oil stored in storage tanks. Modules can be added at a later stage to meet capacity-upgrading demands.
Controllable solid-waste output:
Main solid wastes are saturated adsorbent fillers and filter residues. No large-volume soap-hazardous waste is generated, which eases hazardous-waste disposal pressure and facilitates compliant production for hazardous-waste-treatment enterprises.
Graded oil-product output available: Light fuel oil and base-oil fractions can be output through separate pipelines with respective collection for different products. Customers can flexibly adjust the output ratio of products according to market conditions.
Application Scenarios
- Back-end quality improvement for waste-tire pyrolysis projects: Connect with tire pyrolysis production lines to conduct deep refining on tire-pyrolysis crude oil, remove carbon powder, sulfur and pigments, and produce high-quality base oil and industrial fuel oil.
- Deep-processing project for waste-plastic pyrolysis oil: Process crude oil generated from plastic pyrolysis, remove gums and impurities derived from plastic cracking and increase the commercial value of oil products.
- Refining project for oil-sludge pyrolysis products: Treat crude oil from oil-sludge pyrolysis, remove heavy-metal residues and gums to obtain salable industrial oil products.
- Technical-renovation and upgrading project for aging pyrolysis plants: Add this set of refining equipment for original pyrolysis units with poor oil-product quality to realize oil-product upgrading without modifying the original main pyrolysis unit.
- Independent processing project for purchased pyrolysis crude oil: Purchase external pyrolysis crude oil and conduct independent refining processing to carry out deep-processing business for oil trading.

FAQ
Q1: Can the physical refining plant only be used together with pyrolysis equipment?
A: No. It can work in online connection with pyrolysis units for continuous feeding, or adopt tank style feeding to independently process purchased pyrolysis crude oil. The two production modes are switchable.
Q2: The feed pyrolysis crude oil contains heavy impurities. Is the equipment prone to clogging?
A: The equipment is equipped with a front end multi stage carbon powder removal sedimentation filtration unit specially for removing carbon slag impurities in pyrolysis oil, which greatly reduces clogging risks of the subsequent rectification unit. It is only required to replace filter elements and clean filters periodically in daily operation.
Q3: Does this equipment require large quantities of acid and alkali chemicals?
A: It mainly adopts molecular distillation plus physical composite adsorption technology. Sulfuric acid and caustic soda are not required. Only special adsorbent fillers are consumed. Hazardous wastes are only spent adsorbents and filter residues with low hazardous waste output.
Q4: What finished oil products can the equipment produce?
A: It can produce graded light fuel oil and base oil fractions. Each fraction is collected independently, and the output ratio of each fraction can be adjusted according to market demands.
Q5: Can the equipment adapt to large quality fluctuations of incoming oil feedstock?
A: Equipped with a PLC interlock control system, it can adjust vacuum degree, temperature and feeding speed according to feed in conditions, showing strong adaptability to fluctuations of pyrolysis oil feedstock.
Client References
Our physical refining plant has served numerous waste-oil-regeneration enterprises at home and abroad, including waste-engine-oil recycling processors, tire & plastic pyrolysis factories, hazardous-waste disposal enterprises and oil-blending manufacturers. In implemented projects, the equipment is put into use either as an independent refining production line or as a supporting back-end refining unit for pyrolysis. The purely physical process helps customers avoid hazardous-waste disposal troubles caused by acid and alkali, stably produce qualified regenerated base oil and raise the market selling price of oil products. The DCS automatic-control system reduces on-site manual-operation intensity, and the low-corrosion feature of the equipment cuts customers' later-stage maintenance costs and has won customer recognition. We have established a complete after-sales technical-service system, providing installation guidance and operator training, as well as process-parameter-debugging suggestions for different raw-material properties. We conduct regular follow-ups on equipment operating status and guarantee timely supply of spare parts such as adsorbent fillers and filter elements. Long-term stable partnerships have been built with many customers, and multiple repeat orders and referrals have been obtained with continuously-improved product reputation.
