13-11: Impact of Cooling Water Temperature on Plant Performance

Cooling water play a very vital role in the performance of a plant in terms of the energy utilization / optimization, production and financial earnings (the bottom-line) of the business. The water temperature sets the temperature levels of a water-cooled plant, process or system and hence, its energy utilization, operating costs and/or savings. It is therefore, important to get the cooling water at the right temperature to ensure optimal performance / efficiency of a plant. This paper uses a real-life problem that occurred at the Nigeria Liquefied Natural Gas plant as a case study to show how the performance of a cooling tower impacts the cooling water temperature and hence the overall performance of a water-cooled plant
