To assist clients in evaluating the feasibility of oil sludge pyrolysis projects, Beston Group’s technical team conducted standardized tests on various oil sludge samples from 2023 to 2025, accumulating a database of core performance parameters. All experiments were conducted independently by our quality inspection department, ensuring the rigor and reference value of the monitoring data.
Methodology during Tests
- Subject each oil sludge sample to controlled oil sludge thermal desorption (pyrolysis) conditions.
- Record the time, flue gas temperature and oil production changes for each sample.
- Measure the weight and yield of the pyrolysis products to assess product efficiency.
Conclusion from Tests
Due to the complex nature and diverse origins of oil sludge, oil yields can vary significantly between samples. The data below is for reference only. To determine the precise oil yield of your specific material, we invite you to contact us for a professional laboratory test.
