蒸汽动力系统是石化企业的重要组成部分,也是耗能大户,其任务是将一次能源转换成二次能源,为生产过程提供所需动力、电力、热能和蒸汽等公用工程。如何实施全厂蒸汽动力系统的优化,是石化企业节能降耗的重要途径。20世纪80年代至今,以优化计算方法为支撑的蒸汽动力系统的优化研究比较活跃,夹点分析法、顶层分析法、数学规划法以及R-曲线法相继得到广泛应用;与此同时,国内外相继开发出一系列商品化软件。中国石化(SINOPEC)自2007年引进公用工程设计与调度优化软件Site-Int,已在14家下属企业进行了推广应用,获得了良好的节能效果和经济效益。实践表明,蒸汽动力系统优化技术已经成为中国石化生产企业不可缺少的技术支持与辅助工具,可以帮助企业识别蒸汽动力系统存在的操作瓶颈问题,找到节能改造的机会,从而实现节能减排、降本增效的目的。
Steam power system is an important part of petrochemical enterprises, but also energy-hungry, its mission is to convert primary energy into secondary energy for the production process to provide the necessary power, electricity, heat and steam and other public works. How to implement the whole plant steam power system optimization, petrochemical enterprises is an important way to save energy and reduce consumption. From the 1980s to the present, the optimization of steam-powered systems supported by optimization methods has become more and more active. The pinch analysis method, the top-level analysis method, the mathematical programming method and the R-curve method have been widely used in succession. At the same time, Have developed a series of commercial software. SINOPEC introduced Site-Int, a public utility design and scheduling optimization software, in 2007 and has promoted and applied them to 14 affiliated enterprises and obtained good energy-saving results and economic benefits. Practice shows that the optimization technology of steam power system has become an indispensable technical support and auxiliary tool for Sinopec enterprises, which can help enterprises to recognize the bottlenecks in the operation of steam power system and find opportunities for energy-saving reform so as to achieve energy-saving and emission reduction. The purpose of increasing efficiency.
