Study on the Cooling Water Systems with Multiple Cooling Water Supplies

Water pinch technology is a process integration technology used for enterprises water system optimization, in order to improve the water reuse rate. Application of water pinch point technology to the whole system analysis and design, to establish a feasible performance index, and then determine the detailed process of design and transformation to achieve the predetermined target performance. This paper presents a technique for simultaneous targeting and design in cooling water systems comprising of at least two cooling towers and several cooling water using operations. Through comprehensive analysis on the cooling water systems with multiple cooling water supplies, determine the corresponding heat transfer process to the cooling tower, obtained better results than literature.
