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.
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.
On December 15, 2025, a composite sample of oil-based mud (OBM) drilling waste mixed with plastics was delivered to Beston Group’s technical center for an oil yield pyrolysis test.
| Composition | Unit/g | Ratio/% |
|---|---|---|
| Oil | 37g | 24.67% |
| Slag | 38g | 25.33% |
| Water | 33g | 22% |
On January 23, 2025, Beston Group’s technical center in Jiaozuo received a tank bottom sludge for a pyrolysis performance test. Verified by the quality control team, this evaluation focused specifically on determining the sample’s oil yield potential through our pyrolysis system.

|---|---|---|
| Oil | 125g | 58.7% |
| Slag | 8.5g | 4.00% |
| Water | 65g | 30.5% |
| Composition | Unit/g | Ratio/% |
|---|---|---|
| Oil | 90.5g | 45.25% |
| Slag | 21g | 10.5% |
| Water | 66.5g | 33.25% |
On October 18, 2023, Beston Group received an oil sludge sample for a two-stage test. Our technical team performed the pyrolysis process followed by a distillation test on the material.
| Composition | Unit/g | Ratio/% |
|---|---|---|
| Oil | 255g | 63.75% |
| Slag | 72g | 18% |
| Loss | 73g | 18.25% |
