【摘要】：油頁巖作為最具潛力的石油替代能源之一,其開發(fā)與利用日益得到各界的重視。由于我國富煤、少油、少氣,但具有豐富油頁巖儲(chǔ)量這一能源結(jié)構(gòu)特點(diǎn),使我國很早就進(jìn)行了油頁巖煉制工藝的研究和開發(fā)。目前油頁巖的利用以干餾煉油為主。盡管撫順油頁巖干餾技術(shù)是目前我國較為成熟的干餾技術(shù),但其仍存在以下問題:油頁巖干餾過程的剩余干餾氣未能合理利用;油頁巖干餾過程產(chǎn)生的碎屑頁巖利用程度不高;煉制所得的頁巖油含有大量不利于運(yùn)輸和儲(chǔ)存的雜原子組分,如直接采用外購氫氣進(jìn)行加氫提質(zhì),將導(dǎo)致油頁巖煉制過程的經(jīng)濟(jì)性能欠佳。針對(duì)上述問題,本文提出了一種油頁巖干餾氣重整制氫提質(zhì)的集成煉制新流程,該過程利用干餾過程產(chǎn)生的剩余干餾氣與水蒸氣在CO2吸收劑Ca O的作用下進(jìn)行甲烷水蒸氣重整反應(yīng)制得氫氣,一部分氫氣供應(yīng)給頁巖油加氫提質(zhì)過程,頁巖油經(jīng)加氫提質(zhì)生成柴油、石腦油和LPG,剩余的氫氣作為產(chǎn)品進(jìn)行銷售,油頁巖干餾過程排放的碎屑頁巖為Ca O的再生提供熱量,并實(shí)現(xiàn)熱平衡。整個(gè)過程產(chǎn)生的灰渣送往建材生產(chǎn)單元生產(chǎn)頁巖磚和陶粒以減少環(huán)境污染和提升經(jīng)濟(jì)效益。通過對(duì)集成創(chuàng)新過程和傳統(tǒng)撫順油頁巖煉制過程的建模和模擬,并以模擬流程為基礎(chǔ)對(duì)兩個(gè)過程進(jìn)行了技術(shù)經(jīng)濟(jì)分析,結(jié)果表明這一技術(shù)創(chuàng)新和過程集成使得現(xiàn)有油頁巖煉制過程的投資利潤率從10.53%提高到18.89%。
[Abstract]:As one of the most potential alternative energy sources, oil shale has been paid more and more attention to its development and utilization. Because China is rich in coal, less oil and less gas, it is rich in oil shale reserves. The oil shale refining process has been studied and developed in our country for a long time. At present, the main use of oil shale is distillation oil refining, although Fushun oil shale retorting technology is a relatively mature distillation technology in our country at present. However, the following problems still exist: the residual distillation gas in the oil shale retorting process is not properly utilized, the detrital shale produced by the oil shale retorting process is not utilized to a high degree; The shale oil obtained from the refining process contains a large number of hetero-atomic components that are not conducive to transport and storage. Direct hydrogenation of the oil shale oil by the use of external hydrogen gas will lead to poor economic performance in the oil shale refining process. In this paper, a new integrated refining process for reforming oil shale dry-run gas to produce hydrogen is proposed. The residual distillate gas produced by the distillation process and water vapor react with CO2 absorbent Cao to produce hydrogen. Some of the hydrogen was supplied to the hydrogenation process of the shale oil, which produced diesel oil, naphtha oil and LPG. the remaining hydrogen was sold as a product. The debris shale emitted from the oil shale retorting process provided heat for the regeneration of Cao. The ash produced in the whole process is sent to the building materials production unit to produce shale brick and ceramsite in order to reduce environmental pollution and enhance economic benefits. By modeling and simulating the integrated innovation process and the traditional Fushun oil shale refining process, The technological and economic analysis of the two processes based on the simulation flow shows that the technological innovation and process integration increase the investment profit rate of the existing oil shale refining process from 10.53% to 18.89.
