ABSTRACT:
A method and apparatus for automatically measuring the acidity of overhead water in an oil refinery, and dispensing a neutralizing agent into the refinery system at a rate responsive to that measurement. A sample of overhead water is collected and passed through a filter and cation exchange resin. The acid concentration of the sample is then automatically measured and a signal generated based on the concentration. The signal goes to a controller which controls the dispensation rate of neutralizing agent into the refinery system, thus reducing the acidity of the overhead water and limiting the corrosive effects of such acidity.
