摘要
我国石化行业的低温热系统目前仍旧存在着热源热阱匹配单一、换热网络结构不科学的问题,不运用科学用能的基本原理,以及采用技术经济优化的思想是造成这种现象的根源。在实践中,在更大范围内将更丰富的热源热阱引入低温热系统中,以佣经济学目标函数为指导并实施从模型到工程的系统优化策略,可以生成实用的优化的低温热网络。文中以一个5 Mt/a的炼油企业为例,合成一个低温热系统的年经济效益可达5000万元。
LGH(Low Grade Heat) utility systems in oil refinery of China nowadays were usually had simple and unscientific structures and simple types of heat resource and traps because of the lack of concept on both scientific energy utilization and technical economy optimization.In practice,new type of heat resources and traps had been brought into LGH utility system based on the guidance of exer-goeconomics method from a theoretical model to a real project.The example showed a real LGH network designed by the method...
