Research on VOCs Source Analysis Technology for Petrochemical Enterprises Based on Improved CMB
Petrochemical enterprises are a key source of volatile organic compounds(VOCs)emissions,and studying VOC source apportionment techniques suitable for complex environments in petrochemical enterprises is of great significance for targeted pollu-tion control.An improved weighted CMB algorithm based on feature components was developed,which effectively controled source analysis errors by identif-ying several feature components with the highest sum of squared deviations and increasing weight coeffi-cients.To demonstrate the effectiveness of the algo-rithm,simulated data validation and on-site enter-prise traceability experiments were designed and con-ducted.The results showed that the weighted CMB improved algorithm had better error suppression effect,with a relative error reduction rate of 67.2%in the contribution analysis results compared to con-ventional CMB models.
