Heat exchanger hydrocarbon leaks in refinery cooling water systems cause corrosion, fouling, and loss of heat transfer due to the presence of hydrocarbons and the resulting increased microbiological growth. Typical methods to control microbiological growth in the presence of hydrocarbons include the use of oxidizing and nonoxidizing biocides. Excessive use of these materials can cause additional corrosion and be prohibitively expensive. Common methods of checking exchanger inlets and outlets for hydrocarbon or oxidant residual are often unable to pinpoint a leaking exchanger. This article details two methods to positively identify light and heavy hydrocarbons, using activated carbon or a gas trap followed by gas chromatography. Once the hydrocarbon is identified, the task of finding the leaking exchanger is simplified and corrective measures can be taken.
