PERFORMANCE-BASED CONTROL SYSTEM |
摘要 |
<p>A method and apparatus for detecting and controlling cooling system characteristics is disclosed. A flow rate of make-up cooling medium is measured. A conductivity of the make-up cooling medium is measured. A conductivity of a recirculating cooling medium is measured. A treatment material feed rate is determined based upon the formula: X=(make-up cooling medium flow rate)(make-up cooling medium conductivity)( OMEGA )/(K)(recirculating cooling medium conductivity), where X is a treatment feed rate of a treatment compound, OMEGA is a desired concentration of the treatment compound, and K is a constant. A corrosion rate of the recirculating cooling medium is measured. A desired corrosion rate of the recirculating cooling medium is determined. A feed rate of a corrosion inhibitor is calculated according to the following formula: Y = (X) [1+ alpha (CORRMEASURED/CORRSET POINT)], where alpha is a value between about 0.1 and about 8.0.</p> |
