Abstract:
A degradant concentration measurement device 14 according to the invention has an electric conductivity measurement instrument 71A measuring the electric conductivity of a lean solution 16 that is an acidic gas-absorbing solution and detection means 72 obtaining the concentration of a degradant contained in a lean solution 16 from the measured electric conductivity of the lean solution 16 based on the relationship between the previously-obtained electric conductivity of the lean solution 16 and the concentration of the degradant contained in the lean solution 16.
