Title:
CORROSION MANAGEMENT SYSTEM, WATER TREATMENT DEVICE, POWER PLANT, CORROSION MANAGEMENT METHOD, AND CORROSION MANAGEMENT PROGRAM
Document Type and Number:
WIPO Patent Application WO/2020/230373
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a corrosion management system capable of performing an evaluation of minute amounts of thickness reduction, a water treatment device, a power plant, a corrosion management method, and a corrosion management program. The corrosion management system (31) is to be applied to a power plant where water quality management for suppressing corrosion is carried out during regular operations and is provided with: a detection unit (32) for detecting information regarding a change in the quality of water being used in the power plant; a measurement unit (33) for measuring a thickness reduction amount in piping through which the water flows; and a management device (34) for evaluating, on the basis of the information regarding the water quality change and the measured thickness reduction amount, a correspondence relation between a thickness reduction amount less than a measurement lower-limit value at the measurement unit (33) and an integrated value for the information regarding water quality change.
