Food grade carbon dioxide plant is widely used in coal chemical industry, petrochemical, electric power, alcohol, building materials, ethylene, steel, oil and gas fields and other occasions to recover carbon dioxide gas of different concentrations.

Food Grade Carbon Dioxide Production

Food grade carbon dioxide is mainly used in various carbonated beverages and food preservation. Particularly in carbonated beverages, it plays a crucial role in regulating the flavor and providing a refreshing sensation that helps relieve the heat in summer. The production and manufacturing process of food grade carbon dioxide demands strict compliance with health and safety standards. This is essential to ensure that the final food products are free from harmful substances and microorganisms, safeguarding the health of consumers.

Our production process features mature technology, ensuring safe and reliable operation as well as high yield. Moreover, the operation control system is both reliable and practical, enabling efficient production and easy management.

Minnuo, as a professional gas purification and separation equipment manufacturer and supplier, has rich experience in designing, manufacturing and installing high purity food grade carbon dioxide gas purification equipment. Food grade carbon dioxide plant is widely applied in coal chemical industry, petrochemical,industry electric power, alcohol, building materials, ethylene, steel, oil and gas fields and other occasions to recover carbon dioxide gas of different concentrations. The scale of a single set of food-grade carbon dioxide plant has reached 600kt/a. At the same time, we have successfully developed a complete set of small and fine plants for the production of 50-500kg/h food-grade liquid carbon dioxide by combustion of carbon-containing raw materials, and a carbon dioxide plant of electronic grade quality standard.

Food grade CO2 plants are systems specifically designed to produce and purify CO2 gas that complies with food safety standards. These plants utilize high purity raw materials and advanced filtration and purification technologies to ensure that the output CO2 meets the stringent quality requirements applicable to food processing. They are extensively used in the food industry for aerating carbonated beverages, aerating food packaging to preserve freshness, and as refrigerants in freezing and cooling processes, and are a key component in ensuring food safety and extending product shelf life.

For carbon dioxide gas sources with different impurity contents,we develop diferent production processes.
Apply new condensation equipment to achieve greater energy saving effect and maximize liquefaction condensation effect.
Configuration optimization of the ice machine system to improve refrigeration efficiency, power saving, energy saving and environmental protection.
For the complex sulfur-containing components in the raw gas of food-grade CO2, use effective fine desulfurization proces, H2S, COS, CS2, SO2, thiophene, mercaptan, and mercaptan, etc. are effectively removed to ensure that the total sulfur content of the product is less than 0.1ppm.
Dehydrocarbonization purification patented technology is the most effective way to deal with hydrocarbon, alcohol, aldehyde-containing CO2 gas, the use of catalytic oxidation principle, the company’s dehydrocarbonization process and dehydrocarbonization refining tower of the two patented technology, the CO2 in the harmful hydrocarbons, benzene, aldehydes, alcohols, and all kinds of oxygen-containing organic matter in the most complete removal. The patented equipment has reasonable structure, stable operation, full utilization of energy, self-heating balance operation, no power consumption, and catalyst service life of more than 4 years. The hydrocarbon removal process is an environmentally friendly process with no three wastes.
Proprietary composite purification tower purification equipment, no external power, self-reflux, no power consumption in the liquid CO2 distillation process, low CO2 content in the system exhaust air, high product yield.

Main performance indicators

Parameter	Value
Unit scale	1000~100000t/a
Purity	98%~99.9% (v/v)
Pressure	~2.5MPa（G）
Temperature	~ －15˚C

Technological process

The MDEA residue in the feed gas is removed after the raw material is washed with water, and then compressed, purified and dried to remove trace organic substances such as alcohol in the gas and remove the odor. After distillation and purification, the trace low boiling point gas dissolved in CO2 is further removed, and high-purity food-grade CO2 is obtained and sent to the storage tank or filled.

Application area

Standard
