Carbon dioxide is an odorless, a colorless gas that is stable at room temperature. The organism produces carbon dioxide as a waste of respiration and is then used by plants to form food through photosynthesis. Carbon dioxide also has many industrial and commercial uses, from fire protection to electronic equipment manufacturing.
What is a Co2 compressor?
Physicochemical properties of carbon dioxide
A Co2 compressor refers to a compressor for pressurizing carbon dioxide gas and achieving transportation. Mainly used in urea synthesis equipment. When designing and using, it should be noted that: 1. The critical temperature of carbon dioxide is high, and it can be liquefied at 31.3 °C and 7.14 MPa. When used in winter, the interstage cooling temperature should not be too low; 2. When carbon dioxide is below 60 MPa, it is conducive to gas compression. 3. Because the relative density of carbon dioxide gas is relatively large, it is not appropriate to use an excessively large average piston speed, otherwise the gas valve resistance is large; 4. Carbon dioxide gas contains a small amount of water, which has strong corrosiveness, so the gas valve, cooler and buffer Cans and the like need to be made of stainless steel.
1. Physical properties of carbon dioxide: Carbon dioxide is a colorless and odorless gas at normal temperature and pressure, and is soluble in most organic solvents such as water and hydrocarbons.
2. Chemical properties of carbon dioxide: Carbon dioxide is one of the carbon oxides. It is an inorganic substance that is non-flammable and usually does not support combustion. It is non-toxic at low concentrations. It is also an acid anhydride of carbonic acid, which is an acidic oxide and has the property of an acidic oxide. The valence of the carbon element is +4, which is in the highest valence state of carbon, so carbon dioxide is oxidizing without reduction, but oxidizing. Not strong.
Co2 compressors in various industries
l 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.
Carbon dioxide gas is used in circuit board assembly in the electronics industry to clean surfaces and fabricate semiconductor devices.
Carbon dioxide gas is used for enhanced oil recovery (EOR). Recovery is a type of technology that improves oil recovery in oil fields. Carbon dioxide is injected into the reservoir under high pressure and pushes the oil through the pipeline to the surface. Carbon dioxide gas injection helps to produce oil and reduces the viscosity of the recovered 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.
