This Catalytic Oxidation system is an EPC general contract by Jiangsu Ruiding Environmental Engineering Co designed for Qingdao Siyuan Chemical Co., Ltd. It is specifically used to treat the volatile emissions produced during the manufacturing process of acetone chemical products and the volatile emissions generated during the loading and transportation of the products. The project is an off-gas management initiative under the Qi Xiang Tengda Chemical, which is one of the largest capacity acetone producers in China. This project has significant reference value for the management and recycling of acetone tank area gas in the Chinese chemical industry.

To meet the emission standards of Qingdao City and minimize operational costs as much as possible, we provide an economical solution for the client. Our company adopts a new off-gas treatment process of "cryogenic + CO," breaking away from the traditional cryogenic plus adsorption technology commonly used for tank area gas. This method can efficiently recover solvents such as acetone from volatile harmful gases, allowing them to be reused.

The treatment system can handle 650 Nm³/h of tank area volatile gas + 350 Nm³/h of loading volatile gas. The unit covers an area of 20*10 meters and includes a three-stage condenser recoveree, a reheater, a catalytic reactor, an electric heater, etc. The smoke is emitted in compliance with standards through the combined cryogenic + CO unit.

The project achieved mechanical completion on October 30, 2022, finished commissioning on November 20, 2022, and officially started production and operation in early December 2022.
