DEGRADATION PRODUCT-CONCENTRATION MEASUREMENT DEVICE, AND ACIDIC GAS REMOVAL DEVICE

摘要

A degradation product-concentration measurement device (14) according to the present invention is characterized by being provided with: an electrical conductivity measuring instrument (71A) for measuring the electrical conductivity of a lean solution (16), said lean solution (16) being a pre-obtained acidic gas absorbing solution; and a detection means (72) for obtaining the concentration of degradation products included in the lean solution (16) from the measured electrical conductivity of the lean solution (16), on the basis of the relationship between the concentration of degradation products included in the lean solution (16) and the electrical conductivity of the lean solution (16).
