Carbon dioxide is a colorless and odorless gas, stable at room temperature. This is a waste of breathing, which becomes a photo of a plant during photosynthesis. From fire protection to the manufacture of electronic parts, carbon dioxide is used in many industries.

What is a carbon dioxide compressor?
The carbon dioxide compressor is a compressor used to increase the pressure and delivery of carbon dioxide. Mainly used in urea synthesizer. When designing and using, please pay attention to the following items. 1. The critical temperature of carbon dioxide is high, and it can liquefy at 31.3°C and 7.14 MPa. In winter, the cooling temperature between stages should not be too low. 2. When carbon dioxide is less than 60 MPa, it helps gas compression. 3. Due to the high proportion of carbon dioxide gas, it is impractical to use an excessively high average piston speed, otherwise, the resistance of the gas valve will be very large. 4. Carbon dioxide is corrosive because it contains a small amount of water. Therefore, there are air valves, coolers and buffer tanks. It should be stainless steel.
The physical and chemical properties of carbon dioxide
1. The physical properties of carbon dioxide. At room temperature and pressure, carbon dioxide is a colorless and odorless gas, soluble in most organic solvents, such as water and hydrocarbons.
2. The chemical properties of carbon dioxide: Carbon dioxide is one of the oxides of carbon. It is an inorganic material that does not ignite and generally does not support combustion. Low concentration and non-toxic. It is also an acidic oxide and carbon dioxide with the characteristics of an acidic oxide. The valence of carbon atoms is +4, which means that because carbon atoms have the highest valence, carbon dioxide is reduced without being reduced and oxidized. Not strong
CO2 compressors for various industries
Industrial application
Carbon dioxide gas is used in chemical industry production and as a raw material. According to the "IPCC Special Report on Capturing and Storage of Carbon Dioxide", carbon dioxide gas involves refrigeration systems, welding systems, water treatment processes (to stabilize the pH of water) and the production of carbonated beverages. It is also used in the metal industry to increase the hardness of molds and as a solder. Carbon dioxide is present in various fire extinguishers to prevent oxygen from further contributing to the fire. Carbon dioxide fire extinguishers can effectively manage electrical fires and fires caused by solvents, fuels and oils.
Chemical and medical applications
Carbon dioxide gas is used to make urea (used as fertilizers, automotive systems and medicines), methanol, inorganic and organic carbonates, polyurethanes and sodium salicylate. Carbon dioxide combines with epoxy compounds to form plastics and polymers. Used for water treatment; keeping food cool (such as dry ice); cooling, pressurizing and purification equipment.
Electronic application
Carbon dioxide is used in the assembly of printed circuit boards in the electronics industry for surface cleaning and the manufacture of semiconductor devices.
Oil industry
Carbon dioxide is used to increase oil recovery (EOR). Production is a technology to increase oil production in oil fields. The carbon dioxide is injected into the high-pressure tank, and then the oil is pushed to the ground through the pipeline. Injecting carbon dioxide helps produce oil and reduces the viscosity of the extracted oil.
From a human point of view, whether it is the production of carbon dioxide compressors, oxygen compressors or nitrogen compressors, this is due to population growth. These compressors can bring more beneficial products to mankind, and can also be regarded as a positive point of compressor invention.
