DOING 15-Ton Batch Oil Sludge Pyrolysis System Installed for China Client's Hazardous Waste Treatment project

In March 2025, DOING Company, a professional manufacturer of pyrolysis equipment, completed the installation of a 15-ton batch oil sludge pyrolysis system for a Chinese chemical group. This equipment will be used in the group's integrated hazardous waste treatment project to process lubricating oil filter cake residue (Similar to oil-contaminated sludge pit)– a byproduct from plate and frame filter presses, which has an oil content as high as 50-60%.

Lubricating oil filter cake resudue

The batch pyrolysis system was chosen because it is ideally suited to the unique characteristics of oil sludge filter cake. This oil sludge material has high viscosity and poor flowability, making it difficult to process using continuous methods. Batch operation allows for precise control over each pyrolysis cycle, enabling adjustments based on the complex and variable waste composition. This adaptability ensures thorough treatment of the oil sludge waste while maintaining process stability, which is crucial for hazardous materials like oil sludge filter cake that require careful management.

DOING's batch oil sludge pyrolysis system design addresses the critical challenges posed by catalyst filter cake, including its corrosive nature and tendency to coke during the pyrolysis process. The reactor liner is constructed from 304 stainless steel, capable of withstanding high temperatures and chemical corrosion. To prevent coking, a decoking device is installed inside the reactor to remove deposits, thus maintaining thermal efficiency and reducing downtime. These features enhance the lifespan and stable performance of the pyrolysis system in harsh industrial environments.
