Improve Treatment of Seawater for Cooling New strategies overcome common problems and save money

摘要

MANY CHEMICAL plants across the globe use seawater as a cooling medium.Depending on specific plant cooling requirements,these systems can demand several thousand gallons of fresh seawater makeup per minute.The high volumes of makeup water used represent a significant expense on two fronts:the energy to pump the water and the chemicals to treat it.So,optimizing both seawater demand and chemical treatment strategy is critical.However,plants that rely on seawater for cooling have struggled to do this.For years,conventional seawater cooling programs have used outdated chemistry guidelines that were adapted from freshwater cooling systems or oilfield brines.These adaptations can be imprecise and have led to an unending battle against a range of negative outcomes:high chemical costs,reduced heat transfer efficiency,unscheduled plant shutdowns,lost production,steep maintenance expenses for electrochlorinator units,and excessive water pumping.
