Fine Chemical Industry is one of the most dynamic emerging fields in the chemical industry today, with a wide range of fine chemical products, high added value, a wide range of uses and a high degree of industrial relevance, direct service in the national economy of many industries and high-tech industries in various fields. Fine chemical industry is a comprehensive and technology-intensive industry. In the production process, the process flow is long, unit reactions are numerous and raw materials are complex, and heat exchange is a common link in the production process, the material of heat exchanger is a difficult problem that must be carefully considered in the selection of equipment type because of the high corrosion resistance of equipment. Many processes for Carbon Steel, stainless steel equipment has not been able to meet the production needs, titanium equipment in the acid and corrosion are relatively strong circumstances are easy to be oxidized corrosion, fluorine lining equipment is relatively poor heat transfer effect, and negative pressure resistance, the use of the process is limited, and graphite heat exchanger is made of graphite and polypropylene resin compression, oxidation resistance and organic solvents. Silicon Carbide is a strong corrosion-resistant material. It can resist high concentration nitric acid, mixed acid, Alkali, oxidant and organic chloric acid. The thermal conductivity of SIC is almost equal to that of graphite tube and higher than that of other materials. Its thermal conductivity is 2 times that of Tantalum, 5 times that of stainless steel, 10 times that of Hastelloy and 15 times that of glass-lined. The thermal conductivity of Silicon Carbide makes the heat exchanger have the characteristics of high efficiency and energy saving, and at the same time, the requirement of heat exchange area is reduced greatly.
