Abstract: As volatile organic compounds(VOCs) emission problems of chemical industry park has attracted more and more attention, the choice of VOCs emission control technology in chemical industry park needs scientific, rational, objective and fair evaluation index system and assessment methods. An evaluation index system for VOCs emission control technology based on analytic hierarchy process was developed. For a typical chemical industry park, such as petrochemical industry, the industry distribution and VOCs emission characteristics were analyzed, and screening method of alternative technologies and determination of evaluation index weight were presented. An example to verify the method was also given. Evaluation index system of VOCs emission control technologies in a typical chemical industry park involving eight indexes could be applicable to enterprises in the typical chemical industrial park. The evaluation index system was comprehensive, qualitative and quantitative. A judgment matrix was constructed to calculate the eigenvalues of the matrix and vector features, consistency check was made, and then overall ranking of inter-level indicators was made to determine the weights of all index factors relative to the objective level. Finally, Huizhou Daya Bay Petrochemical Zone was taken as an example. The preferred selection was in the following order:Rotary zeolite adsorption-concentration and combustion > Granular carbon adsorption-concentration and combustion > Regenerative combustion. Rotary zeolite adsorption-concentration and combustion was selected as the best available technology due to its highest weight among those technologies.
