Contamination of feedwater for steam generating plant by carbohydrates, (e.g. sugar in a sugar processing factory) is detected by circulating part of the feedwater through a catalyst (containing platinum or palladium precipitated on quartz crystals), to oxidize the carbohydrates to uronic acid, and subsequently measuring the conductivity or pH of the feedwater. The feedwater is cooled, filtered, deionized and any air bubbles removed to remove inherent conductivity before oxidation, preferably by oxygen dissolved in the feedwater. |
