【摘要】：采用氫氣夾點(diǎn)分析方法,得到煉油廠氫氣流股基本分配方案,然后與計(jì)劃優(yōu)化模型聯(lián)合進(jìn)行優(yōu)化,確定優(yōu)化的氫氣管網(wǎng)方案,并對方案的經(jīng)濟(jì)技術(shù)指標(biāo)進(jìn)行分析,評價(jià)方案的有效性。以國內(nèi)某煉油廠為例,采用上述方案對氫氣系統(tǒng)進(jìn)行優(yōu)化。結(jié)果表明:采用夾點(diǎn)分析技術(shù)可以使氫氣純度滿足煉油廠加工工藝要求,結(jié)合計(jì)劃優(yōu)化模型可以有效地根據(jù)煉油廠生產(chǎn)狀況優(yōu)化氫氣網(wǎng)絡(luò)結(jié)構(gòu),達(dá)到節(jié)氫及優(yōu)化煉油廠原油加工方案的目的;氫氣系統(tǒng)優(yōu)化后可節(jié)約氫氣16.6%,并可加工劣質(zhì)原油、降低原油采購成本,提高煉油廠經(jīng)濟(jì)效益。
[Abstract]:By using the method of hydrogen pinch analysis, the basic distribution scheme of hydrogen flow unit in refineries is obtained, and then the optimized hydrogen pipe network scheme is determined by combining with the plan optimization model, and the economic and technical indexes of the scheme are analyzed. The effectiveness of the evaluation scheme is evaluated. Taking an oil refinery in China as an example, the hydrogen system is optimized by the above scheme. The results show that the purity of hydrogen can meet the processing process requirements of the refinery by means of pinch point analysis. Combined with the plan optimization model, the network structure of hydrogen can be effectively optimized according to the production condition of the refinery, and the purpose of saving hydrogen and optimizing the processing scheme of crude oil in the refinery can be achieved, and after the optimization of the hydrogen system, the hydrogen can be saved by 16.6and the crude oil of poor quality can be processed. Reduce the cost of crude oil procurement and improve the economic efficiency of refineries.
