After reading here and elsewhere that the corrodant in flue gas condensate was carbonic acid, it didn't track with my understanding. So I dug out the original research from the early s by Battelle-Columbus Laboratories for the Gas Research Institute (Report No. GRI/, Technology Development for Corrosion-Resistant Condensing Heat Exchangers). Now that many flue gas desulfurization (FGD) systems are reaching middle age, corrosion repairs of structural and process vessels are becoming more common. Corrosion is caused by condensates of.

resistance to chloride pitting and stress corrosion cracking. They are often selected for flue gas cleaning equipment handling acid condensates, or acidic solutions containing strong oxidants such as in paper bleaching. Where field fabrication is an important consideration, the . removed from such flue gas. This cleaning of me gases can be accomplished by mechanical collectors corrosion probes made up of the following metals were run under controlled-temperature conditions: AIGrade Band AGrade TIl carbon steels, and AISI Types , , , , and stainless. The corrosion behavior of electroless deposited Ni–Cu–P coating in flue gas condensate has been investigated using electron probe micro-analyzer (EPMA), metallographic microscope, differential scanning calorimetry (DSC), polarization curves and electrochemical impedance spectra (EIS).Cited by: Flue gas condensation is a process, where flue gas is cooled below its water dew point and the heat released by the resulting condensation of water is recovered as low temperature heat. Cooling of the flue gas can be performed either directly with a heat exchanger or indirectly via a condensing scrubber.

Latest advances in the understanding of acid dewpoint corrosion: Corrosion and stress corrosion cracking in combustion gas condensates bromine may cause corrosion depending on the flue gas. falls below the dew-point temperature of flue-gas water steam, and water steam from flue gas condensates on the tubes. If water is present, well-soluble chlorides form an aqueous solution or become liquefied, and that can cause intensive electrolytic corrosion even at relatively low temperatures because KCl and CaCl2 are well-soluble compounds. Condensate systems experience corrosion from two major impurities — carbon dioxide and oxygen. The combination of carbon dioxide and water provides the conditions that are necessary for uniform metal loss in the form of grooving, particularly in horizontal runs, and thinning at pipe threads, whereas oxygen corrosion manifests itself as deep pits. Neutralized flue gas condensate before it is discharged into a drain. Increase durability of equipment. h Piping material: Piping material, located between boiler and neutralization kit, will be capable of withstanding acidic environments.
