Heat exchanger is the important equipment in petrochemical industries,whose corrosion protection plays an important role in ensuring the long-term operation of the equipment.As refiners are processing crude oils with increasing sulfur,TAN and impurities,a higher requirement is imposed on corrosion protection and material selection for heat exchangers for petroleum refinery services.The combination protection by coating and sacrificing anode is described in detail.In application of this protection process,the surface should be completed treated,protection electro current must be appropriately selected,the sacrificing anode should be properly designed,the humidity and temperature should be properly controlled and coating should be properly applied to ensure the effective corrosion protection.
