【摘要】：石化企业不仅是能源生产大户,又是能源消费大户。若石化企业能够从自身做起,从源头控制能源消耗,将节能、降耗与合理利用能源深入贯彻到生产的各个环节,势必能为我国节能减排事业做出不小的贡献。国内虽在企业能源审计、能量平衡与软件相结合方面的研究上取得了一定的成果,但关于石化装置节能评估系统软件的开发研究较少。“石化企业耗能装置及设备节能评估系统”则开创了石化类节能评估专业软件的先河,颇具预见性与创新性。本文便基于这套软件展开一系列应用分析研究。本文通过将该软件与“福建漳州古雷炼化一体化”的节能评估相结合,分析项目四十余套炼油、化工装置及相关设备的基础信息,计算并整理出一系列装置及设备信息表,并将其运用到软件节能评估模块的三大单元(能耗统计单元、设备能效评价单元、三环节分析单元)中;而后通过分析软件输出数据,对该项目进行节能评估分析。论文同时分析软件数据库的不足,以期进一步完善数据库,提高软件的实用性和针对性。结果表明:应用该软件可得知项目各装置能耗及用能水平,如催化裂化装置、SSBR装置能耗分别高达48.12kgoe/t原料和40.05kgoe/t原料,项目各装置的能量转化效率、能量利用率、能源利用率分别为91%、70%、65%以上;分析设备能耗可知,若采取节能措施,并使项目大型加热炉、压缩机、机泵设备的整体能效水平提升,年能耗可分别降低2615toe、1081toe、226toe;分析项目整体能耗结构可知,能源消耗比重从高到低依次是煤47.02%、燃料气33.64%、电16.01%、催化烧焦11.63%、蒸汽12.67%、燃料油1.31%、新鲜水0.39%。本文还提出一系列软件改进措施和建议,如增加辅助生产系统的能效分析模块、进一步完善系统数据库、增加程序内部算法、加强软件与网络外源数据库的接洽、优化三环节分析计算模型、增加能源统计单位等。
[Abstract]:Petrochemical enterprises are not only energy production, but also energy consumption. If petrochemical enterprises can control energy consumption from the source and carry out energy saving, consumption reduction and rational utilization to every link of production, petrochemical enterprises will certainly make a great contribution to the cause of energy conservation and emission reduction in China. Although some achievements have been made in the research of energy audit, energy balance and software, few researches have been made on the development of energy-saving evaluation system software for petrochemical plants. Energy consumption equipment and equipment energy-saving evaluation system in petrochemical enterprises has pioneered the professional software of energy-saving assessment in petrochemical enterprises, which is predictable and innovative. This paper is based on this set of software to launch a series of application analysis research. In this paper, the software is combined with the energy-saving evaluation of "Fujian Zhangzhou Gulei Refining and Chemical Integration", and the basic information of more than 40 sets of refinery, chemical plant and related equipment are analyzed, and a series of equipment and equipment information tables are calculated and sorted out. And it is applied to the three main units (energy consumption statistics unit, equipment energy efficiency evaluation unit, three link analysis unit) of the software energy-saving evaluation module. Then through the analysis of the software output data, the project energy-saving evaluation analysis. At the same time, the deficiency of the software database is analyzed in order to further improve the database and improve the practicability and pertinence of the software. The results show that the energy consumption and energy consumption level of each unit, such as catalytic cracking unit and SSBR unit, are as high as 48.12kgoe/t feedstock and 40.05kgoe/t feedstock, respectively, and the energy conversion efficiency of each unit in the project can be obtained by using the software. The energy efficiency and energy efficiency were 91%, 70% and 65% respectively. According to the analysis of equipment energy consumption, if energy-saving measures are taken and the overall energy efficiency level of large-scale heating furnace, compressor and pump equipment is improved, the annual energy consumption can be reduced by 2615 toe, 1081 toeand 226 toerespectively. According to the overall energy consumption structure of the project, the proportion of energy consumption from high to low is 47.02% of coal, 33.64% of fuel gas, 16.01% of electricity, 11.63% of catalytic coke, 12.67% of steam and 1.31% of fuel oil. Fresh water 0.39%. This paper also puts forward a series of software improvement measures and suggestions, such as increasing the energy efficiency analysis module of the auxiliary production system, further perfecting the system database, adding the internal algorithm of the program, and strengthening the contact between the software and the external database of the network. Optimize the three-link analysis and calculation model, increase the energy statistics unit and so on.
