Every 50,000 barrels of oil refined generates 1 trillion BTUs of heat per hour, which is removed by water that evaporates in cooling towers. Large refineries can use more than 10,000 gal per minute. The recent uptick in activity is increasing demand for a finite resource, which prompts a simple question: Has the time come for refineries to re-evaluate their water acquisition strategies and increase their investments in chemical treatment and water reuse. The answer is yes, in areas like the Permian basin with stressed water resources. The right metering pump can be an important contributor to minimizing cooling tower fresh water use and maximizing recirculation Most refineries run continuous operations, and downtime is to be avoided at all costs. The metering pumps used for the water treatment applications should feature hydraulically actuated double diaphragms with leak detection capabilities. HAD pumps operate with equal pressure between the hydraulic and process fluids, which eliminate diaphragm stress because the pressure is equally balanced on both sides at all times. This balance provides longevity for HAD pumps and enables them to operate for 20 years or more, with minimal maintenance. Click Here For Complete Article Text
