Corrosive anions are a notorious enemy of steam-electric power plants, eating away at pipes, turbine blades, and rotors. Continuous monitoring of those anions down to the ultra-trace range is therefore a must in any such facility.
Online ion chromatography provides the technology to meet this challenge, both in terms of sensitivity and robustness, as a project from Taiwan Power Company demonstrates.
At two of their Taiwan sites, Taiwan Power Company is planning to expand its coal-fired power plants to include three ultra-supercritical 800-megawatt units in Linkou, and two in Talin. They are scheduled to go into operation between 2016 and 2021 and will rely on ion chromatography systems from Metrohm for online monitoring of critical anions.
