Internal anti-corrosion for desulfurization tower
Thread Content
Everyone, is anti-corrosion treatment applied inside the desulfurization tower at normal temperatures? What anti-corrosion materials are commonly used?
The desulfurization tower is not at normal temperature during operation; the temperature at the inlet of the dry flue gas is generally above 100 degrees, while the temperature of the wet flue gas after desulfurization is above 50 degrees. For low-temperature, humid flue gas, it causes severe corrosion of metals, so corrosion protection is necessary.

Materials such as fluorinated linings or coated materials are generally used; their temperature resistance is less than 180 degrees, for example, PTFE-lined plates

Corrosion protection is generally required inside the tower, using scale-coating for protection
Desulfurization towers are generally not at room temperature. The commonly used anti-corrosion methods in China are scale-coating anti-corrosion or lining anti-corrosion. Special attention should be paid to corrosion protection at the entrance
