This project utilizes the carbon dioxide tail gas from the by-products of the 1 # and 2 # ethylene glycol units of the Shenghong Integrated Project as the main raw material. Our company provides a proprietary process package design and adopts a combination of catalytic oxidation dehydrogenation and shallow low-temperature distillation process to ensure that the quality of carbon dioxide products is superior to various indicators of food grade products. This device is provided with patents, proprietary equipment, and proprietary catalysts by our company. The project has been fully put into operation in August 2024, and the product quality meets and exceeds the "GB 1886.228-2016 National Food Safety Standard for Food Additives - Carbon Dioxide".
