【摘要】：隨著經(jīng)濟的不斷發(fā)展和資源的日漸緊張,化工行業(yè)需要更加精細(xì)化的操作和合理化的管理。管路運輸是經(jīng)濟有效的輸送流體的方法之一,是化工過程不可或缺的一部分。管網(wǎng)的計劃和調(diào)度問題是當(dāng)下的熱點研究,但目前都沒有同管網(wǎng)設(shè)計相聯(lián)系。本文從管網(wǎng)計劃和設(shè)計、管網(wǎng)調(diào)度和設(shè)計兩個角度同步優(yōu)化綜合管網(wǎng)系統(tǒng)。本研究第一次同步解決多產(chǎn)品網(wǎng)狀管網(wǎng)的設(shè)計和調(diào)度問題。提出了基于Petri-Net表達(dá)的網(wǎng)絡(luò)結(jié)構(gòu),用離散時間表示法混合整數(shù)非線性規(guī)劃模型處理復(fù)雜管網(wǎng)的設(shè)計和調(diào)度問題。提出以最低年度費用為目標(biāo)(管路固定費用、管路操作費用、儲罐固定費用和儲存費用)的規(guī)劃模型優(yōu)化綜合網(wǎng)絡(luò)配置。一個簡化的實際例子說明了所提方法的可行性和有效性。二氧化碳捕獲和封存是減少二氧化碳集中排放源的排放量的主要方法之一。二氧化碳捕獲和封存輸運管網(wǎng)的多周期計劃和設(shè)計問題至今仍沒有研究涉及。針對這個問題,本研究提出基于超結(jié)構(gòu)的數(shù)學(xué)模型,同步解決二氧化碳輸運管網(wǎng)的設(shè)計和多周期計劃問題。用關(guān)聯(lián)矩陣系統(tǒng)表達(dá)管網(wǎng)中地點節(jié)點和管路的連接關(guān)系,運用聚類分析簡化超級結(jié)構(gòu),降低計算復(fù)雜度。在混合整數(shù)非線性規(guī)劃的框架下,模型以項目利潤最大化為目標(biāo)函數(shù),并同時滿足質(zhì)量守恒約束、壓力降約束和邏輯約束。用一個真實的案例說明了所提方法的有效性和優(yōu)勢。分別從計劃和設(shè)計同步優(yōu)化、調(diào)度和設(shè)計同步優(yōu)化兩個角度出發(fā),證明了同步策略具有明顯的經(jīng)濟優(yōu)勢。將計劃、調(diào)度和設(shè)計三者聯(lián)系起來同步優(yōu)化,將是今后的研究重點。
[Abstract]:With the development of economy and the shortage of resources, the chemical industry needs more detailed operation and rational management. Pipeline transportation is one of the economical and effective ways to transport fluid and is an indispensable part of chemical process. The problem of pipeline network planning and scheduling is a hot topic at present, but it is not related to pipe network design. This paper optimizes the integrated pipe network system synchronously from the aspects of pipe network planning and design, pipe network scheduling and design. For the first time, the design and scheduling of multi-product network are solved synchronously. A network structure based on Petri-Net expression is proposed. The discrete time representation is used to mix integer nonlinear programming model to deal with the design and scheduling of complex pipe networks. This paper presents a planning model to optimize the integrated network configuration with the lowest annual cost (pipeline fixed cost, pipeline operation cost, storage tank fixed cost and storage cost). A simplified practical example is given to illustrate the feasibility and effectiveness of the proposed method. Carbon dioxide capture and sequestration is one of the main ways to reduce emissions from concentrated carbon dioxide sources. The multi-cycle planning and design of carbon dioxide capture and sequestration networks have not been studied yet. In order to solve this problem, a superstructure based mathematical model is proposed to solve the problem of carbon dioxide pipeline network design and multi-period planning simultaneously. The connection relationship between the node and the pipeline in the pipe network is expressed by using the correlation matrix system, and the super structure is simplified by cluster analysis, and the computational complexity is reduced. In the framework of mixed integer nonlinear programming, the model takes the project profit maximization as the objective function and satisfies the quality conservation constraints, pressure drop constraints and logical constraints. A real case is given to illustrate the effectiveness and advantages of the proposed method. From the angles of planning and design synchronization optimization, scheduling and design synchronization optimization, it is proved that the synchronization strategy has obvious economic advantages. It will be the focus of research in the future to combine planning, scheduling and design to synchronize optimization.
