Investigation On The Localized Corrosion Performance Of Lean Duplex Stainless Steels In Urban Wastewater Treatment Plants

Product Number: 51322-17756-SG

Author: Audrey Allion, Nicolas Larché, Dominique Thierry, Benoît Emo, Elisabeth Johansson

Publication Date: 2022

$20.00

Wastewater coming from both municipal and industrial activities present corrosive properties toward metals and can in certain cases exceed the tolerances of the most often used stainless steels such as 304L and 316L, thus resulting in the need of superior alloys. The main factors influencing the corrosiveness of the fluids in wastewater treatment plants are high concentration of halides (more specifically chlorides), H₂S, low pH, temperature and their combined action. Corrosiveness of incoming fluids at a municipal wastewater treatment finds its roots in the municipal collection network.

Optimization of FGD Operating Conditions by Electrochemical Laboratory Testing Applied to Alloy UNS S32205

Product Number: 51320-15069-SG

Author: Daniel Betancourt, Steven Kung, Craig Birkenfeld, Jie Wen

Publication Date: 2020

$20.00

Flue gas desulfurization (FGD) systems are frequently used at power plants to remove SO2 from coal combustion. In systems where limestone is utilized, calcium sulfate from the resulting slurry can be concentrated into a valuable byproduct. However, the concentrated slurry containing chloride poses increased localized corrosion risk to the materials of construction in contact with exhaust/combustion stream. Cyclic Potentiodynamic Polarization (CPP) and Critical Crevice Temperature (CCT) present electrochemical methodologies which can be used to assess the relative risk of different conditions in the laboratory. However, the results of these techniques can be dependent on the details of the experimental protocol. In this study, the effect of slurry preparation, potential scan rate, alloy conditioning time, and slurry acidity were examined. A conservative test protocol was developed based on the outcomes of the effects considered, and the critical chloride concentration of Alloy UNS S32205 was determined, enabling optimization of FGD operating conditions.
