Core Technical Challenges of Batch-Type Pyrolysis Oil Refining Equipment

The core technical challenges of batch-type pyrolysis oil refining equipment can be condensed into the following five points, focusing on the key pain points affecting equipment performance:

Oxygen-free Environment Maintenance: Frequent opening and closing of the reactor are required for batch feeding and slagging, which tend to damage airtightness. The challenge lies in overcoming the collaborative technology of high-temperature-resistant sealing and precise oxygen content monitoring.

Precision Gradient Temperature Control: Uneven heat transfer inside the furnace easily leads to insufficient pyrolysis or coking of materials. The challenge is to optimize the furnace structure and temperature control algorithm to achieve uniform temperature control adaptable to multiple raw materials.

Stable Tail Gas Compliance: It is necessary to maintain the secondary combustion temperature at ≥850℃ continuously, while balancing the cost of adsorption materials and the accuracy of emission monitoring to ensure the complete decomposition of pollutants.

Coking Prevention and Cleaning: Carbon deposits generated during pyrolysis will reduce heat transfer efficiency, and batch-type equipment requires shutdown for manual cleaning. The challenge is to develop anti-coking technologies and semi-automatic decoking devices to shorten downtime.

Safety Monitoring and Linkage: Under high-temperature and combustible gas conditions, it is necessary to realize seamless linkage between real-time monitoring of multiple parameters such as temperature and pressure and emergency protection, so as to avoid risks caused by human operation errors.
