High absorption efficiency; High produced acid concentration; Low output temperature; Easy to operate and control; No cooling or drying operation needed for the feed gas, etc;
The absorber is mainly used composed of liquid distributor, cooling and absorption section and gas-liquid seperator, with liquid cooled and absorbed by single-tube film formation. Silicon carbide heat exchanger has the following advantages:
1. Corrosion resistance: silicon carbide is a strong corrosion resistant material, which can resist the erosion of corrosive media such as high concentration nitric acid, mixed acid, alkali, oxidizer and organic chloric acid. Compared with traditional metal heat exchangers and stainless steel heat exchangers, silicon carbide heat exchangers have longer service life and better corrosion resistance.
2. High thermal conductivity: the thermal conductivity of silicon carbide is comparable to that of graphite, which is much higher than other materials, making it able to rapidly transfer heat under high temperature conditions and improve heat exchange efficiency.
3. High temperature resistance: silicon carbide has a high melting point and good high temperature stability, so that the heat exchanger can work normally in a high temperature environment, suitable for high temperature process.
4. Low thermal expansion coefficient: the thermal expansion coefficient of silicon carbide is low, which is conducive to maintaining dimensional stability when the temperature changes and reducing the stress and deformation caused by temperature changes.
5. High strength and oxidation resistance: silicon carbide has high strength and oxidation resistance, can withstand the use of high pressure, high flow rate and high temperature and other conditions, and is not vulnerable to oxidative damage.
6. Light weight and miniaturization: silicon carbide heat exchangers are lighter than metal heat exchangers, which is conducive to the miniaturization and portability of equipment, reducing installation and transportation costs.
7. Clean and environmental protection: The surface of silicon carbide heat exchanger is smooth, not easy to scale, reducing the resistance to the fluid, which is conducive to keeping the fluid clean and reducing maintenance costs.
In short, silicon carbide heat exchangers have significant advantages in corrosion resistance, high temperature performance, thermal conductivity, light weight and miniaturization, and can be widely used in high temperature, high pressure and high corrosion conditions in petroleum, chemical industry, metallurgy, aviation, aerospace and other fields.
