摘要
The influence of environmental factors on the corrosion and the corrosion behavior of carbon steel by aqueous sulfide have been examined by using the weight loss of specimens in immersion tests and electro-chemical methods. The possibility of corrosion-monitoring by electrode-impedance measurement has been examined. Experiments were conducted with sulfide, chloride, and ammonium concentrations between 10 and 1500 ppm, a pH range between 3 and 10, a temperature between 25 and 90-degrees-C, and a fluid velocity between 0 and 3.0m/s. The corrosion behavior of carbon steel depends on the pH value. The corrosion rate of carbon steel increases with increasing temperature and fluid velocity. Corrosion-monitoring by measurement of electrode impedance is possible.
