Chlorine alkali and sulfuric acid industry
Because the alkali and acid production erodes the equipment seriously, therefore only the graphite equipment can bear such high corrosion. So graphite equipment is most widely used in chlorine alkali and sulfuric acid industries.
Graphite equipment’s thermal conductivity, impermeability and anti-corrosion is widely used.
Acid solution is adopted in dyestuff industry, therefore the graphite equipment must be irreplaceable in treatment such as graphite heater, graphite absorber, graphite cooler, graphite evaporator and so on.
Metal surface treatment
The graphite devices are widely used in the processes such as electric pickling solution heating, concentration and so on in stainless steel production.
The mainly used graphite devices nowadays are: the high- temperature reaction equipment, heat-transfer equipment, condensation equipment such as graphite heat exchanger, graphite condenser, steel-lined graphite reactor and reaction tank, concentrating tank, reaction tower, packed tower, phosphoric acid extraction tank, prill tower and so on. Anti-corrosion lining of anti-corrosive equipment, graphite hydration tower, graphite cooler, graphite cooler for sulfuric acid attenuation, graphite evaporator, combustion graphite furnace and so on.
The graphite equipment has strong environmental performance, It has many advantages such as good wear resistance, rare scale, high heat transfer coefficient, small frictional resistance and so on, so it is well accepted in various industries. Graphite chemical equipment has been gradually used in chlorine alkali industry, phosphate and phosphate fertilizer industry as well as fluorine chemical industry, such as hydrofluoric acid and so on.
