What equipment is needed for the production of pyrolysis fuel oil?

Pyrolysis fuel oil production is an innovative thermal decomposition process that converts waste materials into valuable products like fuel oil, carbon black, and syngas. This eco-friendly recycling method helps reduce landfill waste, conserve resources, and generate renewable energy sources. The core of the process involves heating organic materials in an oxygen-free environment to break them down into vapors, which are then condensed into oil. A well-designed pyrolysis equipment ensures high oil yield, energy efficiency, and compliance with environmental regulations.

DOING pyrolysis oil production equipment working process

A standard pyrolysis equipment consists of three primary systems: the pyrolysis reactor heating system, the oil gas cooling system, and the flue gas purification system. These components work together to safely and efficiently process waste into pyrolysis fuel oil.

1. Pyrolysis Reactor Heating System

The pyrolysis reactor is the heart of the operation, where the raw materials undergo thermal decomposition at temperatures between 300-400°C without oxygen, releasing oil vapors, non-condensable gases, and solid residues.

Pyrolysis Reactor: a robust, rotary or horizontal steel vessel (often made of high-temperature-resistant alloy such as Q245R, Q345R or stainless steel ) with a capacity ranging from 100kg-50 tons per batch, depending on plant scale. It features a rotating or fixed design to ensure even heating and prevent material clumping. The reactor includes a sealed feeding door and discharge ports for residues like carbon black.

Heating System: External burners or hot air furnace fueled by initial sources such as fuel oil, natural gas, wood, or coal. Once pyrolysis begins, the system can recycle self-generated non-condensable syngas to sustain the reaction. This closed-loop heating drastically reduces external fuel costs and improves the overall energy efficiency of the system.

Safety Features: Pressure and temperature sensors, automatic shut-off valves, insulation layers and vacuum negative pressure device to maintain vacuum conditions and prevent explosions.

2. Oil Gas Cooling System

Once generated, the hot oil vapors must be rapidly cooled and condensed into liquid pyrolysis fuel oil. This step is crucial for achieving high yields, as incomplete condensation leads to oil loss as emissions.

Condensers: This is the workhorse of the cooling process. A sophisticated condenser system, often comprising multiple stages, is employed to efficiently transfer heat away from the oil gas. Henan DOING offers two design options:

1.Shell-and-tube condensers: mainlyt including 2 sets of vertical condensers and 2 sets horizontal condensers which is the most professional cooling systen of industries. Also there is a set of oil- water seperator and two sets of cooling tower which definately will get all the oil gas to be coolled down during producing to improve the oil yield.

2. Water tank condensers: composed of multiple cooling tubes, offering a large cooling area and easy installation.

Oil-Water Separator: Pyrolysis oil often contains a certain amount of water. The oil-water separator is an indispensable component that separates the liquid pyrolysis oil from any entrained water. This is vital for producing clean, high-quality oil that can be stored and used effectively without issues arising from water contamination.

Storage Tanks: Insulated tanks to store the final pyrolysis oil.

3. Flue Gas Purification System

Pyrolysis generates flue gases from combustion and minor emissions from the reactor, containing dust, sulfur oxides, nitrogen oxides, and particulates. An effective purification system treats these to meet stringent environmental standards.

Dust Removal: A dedusting chamber captures fly ash and particulate matter.

Desulfurization: An alkali spray tower or desulfurization tower neutralizes and removes sulfur dioxide and other acidic components, significantly reducing the emission of harmful gases.

Activated Carbon Adsorption (Optional): For higher emission standards, an activated carbon filter can be added to absorb any remaining dioxins or odors.

Beyond the core systems, a complete pyrolysis equipment includes:

Waste pretreatment equipment: tire plastic shredding equipment, tire wire removing machine, oil sludge dewatering centrifuge, etc.

Material handling system: An automatic feeder, elevator, or manual loading system used to deliver raw materials into the reactor.

Decoking system: The decoking unit in the pyrolysis reactor is crucial. It removes sticky carbon residues and polymers accumulated on the inner walls. This prevents clogging, ensures continuous heat transfer, thereby stabilizing oil production and significantly reducing downtime for manual cleaning, improving overall operating efficiency.

Control System: PLC-based automation for monitoring temperature, pressure, and flow, reducing labor needs.
