抚顺石化汽油加氢装置用能分析及节能措施

通过对比发现,抚顺石化120万吨/年汽油选择性加氢装置能耗在国内同类装置中处于中等水平,尚有进一步节能潜力。根据用能三环节原理对装置用能情况进行了分析,分析表明,装置的能源消耗主要为燃料气、电和3.5 MPa蒸汽,这3方面是装置节能的关键所在。本文针对这3方面分别提出了具体的改进措施。采取节能措施后,节能效果显著,装置平均能耗降到17.06 kg Eo/t原料,在国内同类装置能耗中处于先进水平。

Energy Analysis and Energy Saving Measures of Fushun Petrochemical Gasoline Hydrogenation Unit

By comparison,the energy consumption of Fushun Petrochemical 1. 2 million tons / year gasoline selective hydrogenation unit was in the middle level of the domestic similar device,which had further energy saving potential. The unit＇s energy consumption was analyzed by the three-link energy-use analysis model,the analysis showed that the energy consumption of the device was mainly for fuel gas,electricity and steam of 3. 5 MPa,and these three aspects were the key to devices energy saving. Some specific measures were put forward for these three areas. After took these energy-saving measures,the energy-saving effect was remarkable,the unit＇s average energy consumption droped to 17. 06 kg Eo / t raw materials,and energy consumption level kept ahead in the domestic similar device.
