【摘要】：氫夾點(diǎn)技術(shù)自20世紀(jì)90年代末被提出至今,在解決氫氣網(wǎng)絡(luò)用氫瓶頸上,已經(jīng)有了成熟穩(wěn)健的發(fā)展,為氫氣網(wǎng)絡(luò)優(yōu)化提供了理論和技術(shù)支持。目前,氫夾點(diǎn)技術(shù)方法主要包括:剩余氫量圖解法、嚴(yán)格氫夾點(diǎn)圖解法、源組合曲線法、氫負(fù)荷-流量圖法、多雜質(zhì)赤字率圖解法等,氫夾點(diǎn)方法經(jīng)過(guò)不斷的發(fā)展,基本都能優(yōu)化現(xiàn)有的各種氫氣網(wǎng)絡(luò)瓶頸問(wèn)題,對(duì)于不同的優(yōu)化目標(biāo),采用不同方法進(jìn)行求取,能夠給煉廠帶來(lái)明顯的經(jīng)濟(jì)效益。本文首先對(duì)以上幾種氫夾點(diǎn)技術(shù)方法進(jìn)行了分析研究,并對(duì)每種方法進(jìn)行了具體的評(píng)價(jià),包括適用范圍、優(yōu)點(diǎn)和不足。建立各方法的數(shù)學(xué)模型和求解方法,并基于一種簡(jiǎn)單高效、解釋性強(qiáng)、擁有強(qiáng)大的科學(xué)計(jì)算庫(kù)的編程語(yǔ)言--Python編程語(yǔ)言對(duì)所建立的數(shù)學(xué)模型進(jìn)行實(shí)現(xiàn),工業(yè)用氫網(wǎng)絡(luò)夾點(diǎn)分析系統(tǒng)在實(shí)現(xiàn)過(guò)程中使用了大量的開(kāi)源科學(xué)計(jì)算庫(kù),減少了代碼的長(zhǎng)度,同時(shí)增強(qiáng)了代碼的可讀性,可以節(jié)省大量的時(shí)間。開(kāi)發(fā)了工業(yè)用氫網(wǎng)絡(luò)夾點(diǎn)分析系統(tǒng),用戶通過(guò)輸入氫源和氫阱的相關(guān)數(shù)據(jù),進(jìn)而選擇不同的氫夾點(diǎn)求取方法,可以直接求取氫夾點(diǎn)以及相關(guān)數(shù)據(jù),由于各方法的求解方式不同,針對(duì)點(diǎn)不同,因此,各種方法求解的變量也有所不同。最后,通過(guò)煉廠的實(shí)際生產(chǎn)實(shí)例對(duì)工業(yè)用氫網(wǎng)絡(luò)夾點(diǎn)分析系統(tǒng)中所包含的5種氫夾點(diǎn)技術(shù)方法進(jìn)行模擬測(cè)試,結(jié)果對(duì)比與分析,從實(shí)際生產(chǎn)的角度驗(yàn)證了該夾點(diǎn)分析系統(tǒng)的穩(wěn)定性和準(zhǔn)確性。綜上,該工業(yè)用氫網(wǎng)絡(luò)夾點(diǎn)分析系統(tǒng)開(kāi)發(fā)具有較大的實(shí)用價(jià)值,能夠成為后續(xù)氫氣網(wǎng)絡(luò)夾點(diǎn)分析的研究和發(fā)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.
