Product Name
Pyrolysis Oil Refinery. It is a complete deep-processing unit for pyrolysis oil integrating pretreatment, rectification and hydro-upgrading combined processes. It performs desulfurization, denitrification, gum removal and pour-point reduction upgrading on crude pyrolysis oil from waste tires, waste plastics and oil sludge. It converts inferior crude pyrolysis oil into qualified diesel fractions and base-oil fractions and enables large-scale continuous production. It is suitable for solid-waste pyrolysis-supporting oil-refining projects of medium size and above.

Features
Multi-stage pretreatment & purification unit:
The pyrolysis oil refinery integrates combined modules of heat-exchange sedimentation, precision filtration and acid-gum removal. It removes carbon ash, organic acids, gums and asphaltenes from pyrolysis oil step-by-step, lowers the load of subsequent rectification and upgrading units, protects hydrotreating catalysts and extends catalyst service life.
Combined rectification-hydro-upgrading process:
It adopts the combined process of rectification cutting and low-pressure hydro-upgrading. Light-heavy fraction cutting is completed first, followed by hydro-upgrading of heavy fractions to improve oil pour point, color and oxidation stability, solving the pain point of easy oxidation and discoloration of pyrolysis oil.
Catalyst cyclic protection system:
The pyrolysis oil refinery is equipped with a feed pre-protection filter bed to intercept heavy metals and solid impurities and avoid catalyst poisoning. Matching catalyst loading and unloading interfaces are provided for convenient later-stage catalyst replacement and regeneration.
Closed-loop hydrogen recovery circuit:
Unreacted hydrogen from hydrotreating is recycled after cooling, separation and compression to reduce hydrogen consumption. Sulfur-containing waste gas is sent to the desulfurization unit to achieve compliant waste-gas discharge.
Dual DCS+SIS safety control system:
Equipped with distributed control system and safety interlock protection system, it automatically triggers interlock pressure relief and shutdown upon over-temperature, over-pressure or abnormal liquid level to guarantee production safety of the whole continuous unit.
Advantage
Combined rectification-hydro-upgrading for substantial oil-quality improvement:
Different from simple physical refining, hydro-upgrading chemically decomposes sulfide and nitride molecules, reduces sulfur and nitrogen content and improves oil oxidation stability. Produced oil indexes are close to national-standard diesel and base-oil specifications.
Suitable for continuous large-and-medium-capacity production:
The complete pyrolysis oil refinery supports 7×24-hour continuous operation with large processing capacity. It fits medium-scale continuous pyrolysis production lines, and large-scale production reduces unit processing costs.
Recycled hydrogen with controllable operating energy consumption:
Closed-loop hydrogen recycling requires only small make-up fresh hydrogen. High comprehensive material utilization effectively cuts auxiliary-material operating costs.
Complete safety interlocks to mitigate production risks:
The SIS safety-interlock system covers high-pressure hydrotreating zones. Automatic protection under abnormal conditions eliminates potential safety hazards of high-pressure hydro-processing.
Flexible and adjustable product schemes: It can prioritize output of diesel fractions or base-oil fractions according to customers' market demands. Process parameters can be adjusted on-line to adapt to different pyrolysis feed oils.
Application Scenarios
- Supporting refining project for large-scale continuous tire pyrolysis: Connect to high-capacity tire pyrolysis production lines for hydro-upgrading of crude pyrolysis oil to produce high-quality diesel and base-oil fractions.
- Quality-improvement project for waste-plastic pyrolysis oil: Process crude oil from various plastic pyrolysis, remove sulfur-nitrogen impurities, improve oil stability and raise product market value.
- Deep-processing project for oil-sludge pyrolysis products: Crude oil from oil-sludge pyrolysis goes through pretreatment-rectification-hydrotreating to remove heavy metals, sulfur and nitrogen and obtain compliant industrial-grade oil products.
- Expansion & upgrading project for existing pyrolysis plants: For original pyrolysis projects that only produce crude fuel oil, add this pyrolysis oil refinery to realize oil-quality upgrading and expand product sales channels.
- Centralized-processing park project for purchased crude pyrolysis oil: Receive crude pyrolysis oil purchased from surrounding factories and conduct centralized hydro-refining for professional deep-processing of oil products.
Packing & Shipping
Equipment modules are split to fit 40HQ container dimensions. Extra-long and extra-large pressure-vessel components are shipped by bulk ro-ro vessel. Complete packing lists are provided and customers' on-site loading supervision is supported.
FAQ
Q1: What is the core difference between the pyrolysis oil refinery and ordinary physical refining equipment?
A: This unit adds a low pressure hydro upgrading procedure. Instead of mere physical separation, it chemically removes sulfur and nitrogen and improves oil stability and pour point. Physical refining only performs physical decolorization and impurity removal and hardly addresses sulfur nitrogen and stability issues. This unit fits projects with higher oil index requirements.
Q2: Are there any requirements for incoming crude pyrolysis oil feedstock?
A: Most carbon powder and mechanical impurities shall be removed in advance. Feed stock water content must be strictly controlled to prevent shortening hydrotreating catalyst service life.
Q3: Does the hydrotreating process consume large continuous quantities of hydrogen?
A: The unit is equipped with a closed loop hydrogen recycling system. Most unreacted hydrogen is recycled and only a small amount of fresh hydrogen needs to be supplemented, resulting in low overall hydrogen consumption.
Q4: What quality level can the produced oil products reach?
A: After rectification and hydro upgrading, it can produce low sulfur diesel fractions and regenerated base oil fractions with indexes close to national standards. Products can be sold directly or further blended into finished oil.
Q5: Must this unit be matched with pyrolysis equipment?
A: No. It can either be pipeline connected to upstream pyrolysis units for continuous feeding, or use tank received purchased crude pyrolysis oil for independent refining and upgrading production.
