【摘要】：氢夹点技术自20世纪90年代末被提出至今,在解决氢气网络用氢瓶颈上,已经有了成熟稳健的发展,为氢气网络优化提供了理论和技术支持。目前,氢夹点技术方法主要包括:剩余氢量图解法、严格氢夹点图解法、源组合曲线法、氢负荷-流量图法、多杂质赤字率图解法等,氢夹点方法经过不断的发展,基本都能优化现有的各种氢气网络瓶颈问题,对于不同的优化目标,采用不同方法进行求取,能够给炼厂带来明显的经济效益。本文首先对以上几种氢夹点技术方法进行了分析研究,并对每种方法进行了具体的评价,包括适用范围、优点和不足。建立各方法的数学模型和求解方法,并基于一种简单高效、解释性强、拥有强大的科学计算库的编程语言--Python编程语言对所建立的数学模型进行实现,工业用氢网络夹点分析系统在实现过程中使用了大量的开源科学计算库,减少了代码的长度,同时增强了代码的可读性,可以节省大量的时间。开发了工业用氢网络夹点分析系统,用户通过输入氢源和氢阱的相关数据,进而选择不同的氢夹点求取方法,可以直接求取氢夹点以及相关数据,由于各方法的求解方式不同,针对点不同,因此,各种方法求解的变量也有所不同。最后,通过炼厂的实际生产实例对工业用氢网络夹点分析系统中所包含的5种氢夹点技术方法进行模拟测试,结果对比与分析,从实际生产的角度验证了该夹点分析系统的稳定性和准确性。综上,该工业用氢网络夹点分析系统开发具有较大的实用价值,能够成为后续氢气网络夹点分析的研究和发展的有力工具。
[Abstract]:Since the hydrogen pinch technology was put forward in the late 1990s, there has been a mature and steady development in solving the hydrogen bottleneck of hydrogen network, which provides theoretical and technical support for hydrogen network optimization. At present, hydrogen pinch technique mainly includes: residual hydrogen quantity graphic method, strict hydrogen pinch point diagram method, source combination curve method, hydrogen load-flow chart method, multi-impurity deficit rate graphic method, etc. Hydrogen pinch point method has been continuously developed. All of the existing hydrogen network bottleneck problems can be optimized basically. For different optimization objectives, different methods can be used to obtain them, which can bring about obvious economic benefits to refineries. In this paper, the above several hydrogen pinch techniques are analyzed and studied, and each method is evaluated, including the scope of application, advantages and disadvantages. The mathematical model and solution method of each method are established, and the mathematical model is realized based on a simple, efficient, explanatory and powerful programming language, Python programming language, which has a powerful scientific computing library. In the industrial hydrogen network pinch analysis system, a large number of open source scientific computing libraries are used in the process of implementation, which reduces the length of the code, enhances the readability of the code, and saves a lot of time. A hydrogen network pinch analysis system for industrial use is developed. By inputting the relevant data of hydrogen source and hydrogen trap, and then selecting different methods to obtain hydrogen pinch point, the hydrogen pinch point and related data can be directly obtained. Because of different points, the variables solved by various methods are different. Finally, through the actual production example of refinery, the paper simulates and tests five kinds of hydrogen pinch technical methods contained in the industrial hydrogen network pinch analysis system, and the results are compared and analyzed. The stability and accuracy of the pinch analysis system are verified from the point of view of actual production. In summary, the development of the industrial hydrogen network pinch analysis system is of great practical value and can be used as a powerful tool for the subsequent research and development of hydrogen network pinch analysis.
