IWC 20-58: The Value (and the Challenges) of Corrosion Transport Monitoring (2020 Best Overall Paper Award)
Colleen M. Scholl, P.E., HDR
Monitoring of corrosion products in power plants is an indicator of the success of the cycle chemistry program. This paper will discuss the value of instituting a formal corrosion transport monitoring program and detail the effort involved in optimization of a plant specific program. It will review methods for corrosion transport monitoring in steam generator cycles including the associated benefits and limitations. Case studies will be utilized to illustrate the process and the obtainable benefits.
IWC 20-66: Controlling Oxidation Air in an FGD Absorber as a Means to Simplify Wastewater Treatment (2020 First Time Presenter Award)
Adam Sutherland, P.E., Stantec; Lindy Johnson; Bill Kennedy, Stantec
This paper presents experiences and benefits of a full scale installation of an oxidation air control system in a wet FGD application. Benefits include significant operational cost savings and improved wastewater treatability using chemical precipitation to aid compliance with EPA’s proposed 2019 ELGs for selenium and mercury. Liquor sulfite concentration as well as unit load and inlet SO2 are used to control the oxidation air flow rate to the absorber reaction tanks of a once through forced oxidation FGD scrubber. Impacts to the scrubber and wastewater chemistry will be described including comparisons to pre sulfite controlled operations.
