It can be determined through factors such as the temperature rise of the catalyst, changes in the pH of the quench water, corrosion monitoring using samples from the pipelines, and exhaust emission data. The darkening of the quench water is mainly caused by the presence of carbon, sulfur in the process gas, corrosion products, and inadequate cleaning of the system
