Available in PDF, EPUB and Kindle. Book excerpt: In this book, the authors, Dr. Chris Hunt and Graham K. Naisbitt of GEN3, examine the role of SEC test and how it is used in maintaining process control and support for objective evidence. SEC equipment and technical details are also considered, where the equipment approach and methodology of operation are evaluated. Issues, including solution choices, solution sensitivities, and test duration are explored. The effect of CO2 absorption is dealt with and how instruments correct for this. Solution density changes and temperature effects are discussed. The two configurations of "open" and "closed" loop circulation are reviewed. This book covers important elements of process control that relate to corrosion. It is important to avoid ECM, and here we have covered the initial objective evidence exercise of using SIR to verify a process, and then the maintenance of that process using SEC, as described in the PICT test. Finally, parameters of the SEC technique are reviewed, highlighting key sensitivities.
