| Summary: | In order to solve the problem of incomplete construction of energy-saving and emission-reduction technology evaluation system in the petrochemical industry, this study focused on energy-saving and emission-reduction technologies in the petrochemical industry, constructed an evaluation index system based on technical performance, economic benefits, and environmental protection using the CRITIC-cloud rating model. The research findings indicated that over 75% of energy-saving and emission-reduction technologies in the petrochemical industry score is above 0.6 in comprehensive evaluation. Benchmark technologies include variable frequency drive energy-saving technology, steam system operation optimization and energy-saving technology, and large-scale high-parameter plate-shell heat exchange technology. Significant differences are observed in the maturity, applicability, emission reduction costs, and reduction potential of energy-saving and emission-reduction technologies in the petrochemical industry. Technologies such as multi-energy complementary DC microgrid and pump energy-saving group control system technology, and high-efficiency heat exchange technology with porous surface high-flux tubes require should be improved in economic and environmental benefits; The cloud model evaluation shows that the whole energy-saving and emission-reduction technologies in the petrochemical industry reach an "acceptable" level and are gradually towards a "claimable" level. The research results provide evaluation criteria for the development of energy-saving and emission-reduction technologies in the petrochemical industry from a technical assessment perspective, and aids in achieving the goals of carbon neutrality. |
