Product Parameters

1. Flue gas generally refers to the high temperature and low carbon dioxide concentration tail gas emitted by power plants, boiler plants, lime kilns, cement plants, etc., from coal, gas, oil or heating. The flue gas contains 8-35% CO2. This system uses MEA to absorb carbon dioxide at room temperature. After the concentration section, the carbon dioxide undergoes adsorption, drying, cooling, heat exchange and enters the rectification tower for rectification to remove sulfur and nitrate. Impurities such as oxygen, nitrogen and water vapor are stored in storage tanks for users to use;
2. Petrochemical and chemical exhaust gas generally refers to the high-concentration carbon dioxide tail gas emitted from the reaction and separation devices of petrochemical plants, fertilizer plants, hydrogen plants and other chemical plants. Petrochemical and chemical exhaust gases generally contain 80-99% CO2, as well as impurities such as sulfur, carbon monoxide, hydrogen, nitrogen, oxygen, benzene, and water vapor. The stupid system uses water washing, water separator to remove dust and cool down, special adsorbent adsorption, desulfurization, dehydration and hydrocarbon removal, and combined with distillation tower distillation to remove methane, hydrogen, nitrogen, carbon monoxide, oxygen and other impurities;
3. Fermentation gas generally refers to the high-concentration carbon dioxide tail gas emitted from fermentation systems such as alcohol factories, breweries, sugar factories, etc., generally containing 90-99% CO2, as well as alcohols, aldehydes, methane, hydrogen, nitrogen, water vapor, etc. Impurities, may contain a small amount of carbon monoxide and oils. This system uses a combination of water washing, water separation and special adsorbents to remove alcohols, aldehydes, and the like, carbon monoxide, etc., and removes water through drying, cooling, heat exchange, and distillation in a distillation tower. , Methane, hydrogen, nitrogen and other impurities;

1. The whole set of equipment adopts a targeted design method, that is, different designs are carried out for the raw gas of different components of the user, while ensuring product functions, minimize equipment investment and operating energy consumption;
2. The equipment is concise, the area is small, and the installation is convenient;
3. It adopts a distributed control system (DCS system), which is easy to operate and can realize unattended operation for 24 hours continuous operation;
4. The carbon dioxide contact part of the whole set of equipment is made of stainless steel, which is safe and stable;
5. Product quality is stable and reliable, product carbon dioxide purity >=99.99%, in line with food additive carbon dioxide standard (GB1886.228-2016);
