Advantages and Disadvantages of Continuous Pyrolysis Oil Extraction Equipment

Advantages and Disadvantages of Continuous Pyrolysis Oil Extraction Equipment

Advantages

High production efficiency: Continuous feeding and slag discharge with no batch waiting time, the daily processing capacity can reach 50–300 tons, suitable for large-scale production.

Low energy consumption & high thermal efficiency: The furnace operates at a constant high temperature without repeated heating, the unit energy consumption is 20–40% lower than that of batch-type equipment, and the energy utilization rate is high.

High automation level: Full-process PLC control, automatic feeding, pyrolysis, slag discharge and oil-gas separation, low labor demand and labor intensity.

Excellent environmental performance: Sealed and continuous operation ensures stable emission of flue gas and dust, small fluctuation in tail gas treatment load, and easier achievement of ultra-low emission standards.

Stable product quality: Continuous controllable process parameters result in stable oil-gas composition and oil yield, as well as more uniform carbon black quality.

Good scalability: Capacity can be expanded through modular design, suitable for large-scale environmental protection projects and large-scale waste treatment needs.

Disadvantages

High investment cost: Complex equipment structure and high automation lead to a unit cost 2–5 times that of batch-type equipment, requiring large upfront capital investment.

High technical threshold: Complex control systems and pyrolysis processes demand high professional skills and operation & maintenance capabilities of the operators.

Poor flexibility: Under continuous operation mode, the start-stop cost is high and the cycle is long, making it difficult to adapt to working conditions with large fluctuations and scattered raw material supply.

High maintenance difficulty: Continuous equipment operation causes fast wear of key components (e.g., feeding seals, high-temperature furnace linings, heat exchange systems), leading to complex maintenance and significant impact of shutdowns on production.

Large floor space: Multiple supporting systems (feeding, slag discharge, oil-gas treatment, automatic control) result in a larger overall floor space than batch-type equipment.
