摘要:

循环冷却水系统是乙烯装置公用工程的关键组成部分,其设计合理性直接影响乙烯装置的稳定性、安全性和经济性。文中以国内某1 000 kt/a乙烯装置为例,系统阐述循环冷却水管网的设计原则,重点探讨枝状/环状管网布局、二次水系统集成等关键设计问题,并详述如何利用PIPENET软件进行水力建模、管径优化及偏流问题诊断的方法。采用科学的水力计算方法并结合最优解的动态调整,可显著提升系统能效,降低装置的投资与运行成本。

Abstract:

Circulating cooling water (CW) system is a critical component of utility systems in ethylene plants. Its design rationality directly affects the stability, safety, and economic performance of ethylene plants. Based on a case study of a 1.0 Mt/a ethylene plant in China, this paper systematically elaborates on the design principles for CW networks. Key design aspects such as the branched/looped network layouts and the integration of secondary water systems are discussed. The application of PIPENET software in hydraulic modeling, pipe diameter optimization, and diagnosis of flow distribution issues is also described in detail. Scientific hydraulic calculation methods and dynamic adjustment strategies can significantly enhance the energy efficiency of the system while reducing both the capital investments and operational costs of ethylene plants.
