What is a Co2 compressor?

Carbon dioxide compressors are compressors used to increase the pressure and transportation of carbon dioxide. Mainly used in urea synthesizers. When designing and using, please pay attention to the following. 1. The critical temperature of carbon dioxide is high and can be liquefied 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. Because the specific gravity of carbon dioxide gas is large, it is impractical to use an excessively high average piston speed, otherwise, the resistance of the gas valve will be great. 4. Carbon dioxide is very corrosive because it contains a small amount of water. Therefore, there are air valves, coolers and buffer tanks. It should be stainless steel.

Physicochemical properties of carbon dioxide

1.The physical properties of carbon dioxide. At room temperature and pressure, carbon dioxide is a colorless, odorless gas that is soluble in most organic solvents, such as water and hydrocarbons.

2. Chemical properties of carbon dioxide: carbon dioxide is one of carbon oxides. It is an inorganic material that does not ignite and generally does not support combustion. Non-toxic at low concentrations. It is also acidic oxide and carbon dioxide with acidic oxide characteristics. The valence of the carbon atom is +4, which means that since the valence of the carbon atom is the highest, carbon dioxide is reduced without being reduced and oxidized. Not strong

Co2 compressors in various industries

Industrial application

Carbon dioxide gas is used in industrial production of chemicals and as a raw material. According to the "Special Report of the IPCC on the capture and storage of carbon dioxide", carbon dioxide gas relates to 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 casting molds and as a soldering agent. Carbon dioxide is present in various fire extinguishers to prevent oxygen from further contributing to the fire. Carbon dioxide fire extinguishers effectively manage electrical fires and fires caused by solvents, fuels and oils.

Chemical and medical applications

Carbon dioxide gas is used in the manufacture of urea (used as fertilizers and automotive systems and pharmaceuticals), methanol, inorganic and organic carbonates, polyurethanes and sodium salicylates. Carbon dioxide combines with epoxy compounds to form plastics and polymers. Used for water treatment; keep food cool (such as dry ice); cool, pressurize and purify equipment.

Electronic applications

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 improve oil recovery (EOR). Production is a technique to increase oil production in oil fields. Carbon dioxide is injected into the high-pressure tank, and the oil is pushed to the ground through the pipeline. The injection of carbon dioxide helps oil production and reduces the viscosity of the extracted oil.

From the perspective of human beings, whether it is producing Co2 compressors, oxygen compressors or nitrogen compressors, it is due to population growth. These compressors can bring more favorable products to humans, and can also be regarded as a positive point of the invention of the compressor.
