This project provides energy-saving solutions for volatile organic compound (VOC) treatment equipment in the semiconductor, optoelectronics, chemical, and other traditional industries. It develops an integrated system of energy-saving adsorption concentration and regenerative thermal oxidation, which fully recovers waste heat, enhances VOC combustion efficiency, and reduces energy consumption. Key components of the system, such as activated alumina adsorption spheres and alumina heat storage ceramics, were made from active alumina and alumina extracted from aluminum dross. Recycling aluminum dross reduces landfill waste and carbon dioxide emissions, while addressing the issue of high imported material costs. Currently, extracted activated alumina has a purity over 99%, energy savings over 15%, and cost reduction by one-third. The integrated system of adsorption concentration and regenerative thermal oxidation achieves a removal rate over 98%, meets regulatory standards, and recovers over 96% of waste heat using regenerative ceramics and heat exchangers, which is comparable to the level of commercial regenerative thermal oxidizers.
