摘要/Abstract

摘要： 桦甸式油页岩气体热载体综合利用工艺是一种重要的油页岩利用方式，本文在原有综合利用系统的基础上做了部分改造，将小颗粒油页岩和半焦混合气化后再与干馏气一起送入燃气-蒸汽联合循环系统发电，同时利用燃机尾气加热循环热载体。利用Aspen Plus软件对原有及改造后的油页岩综合利用系统进行建模，并根据模拟数据对综合利用系统作进一步的能量分析和（火用）分析。结果表明：改造后的综合利用系统总的一次能量利用效率和（火用）效率分别达到了58.23%和60.18%，远高于原有系统，其中各主要单元的能量利用效率和（火用）效率均高于60%；另外，提高油页岩干馏比例可以明显增加系统页岩油产量，虽然电能输出会有所降低，但总（火用）效率会随之增长。

Abstract: The comprehensive utilization system of Hua-dian oil shale,which uses gaseous heat carrier technology,is an important utilization method of oil shale. Some parts of the system are modified in this paper,and the retorting gas and the syngas produced by the gasifier are fed into the gas-steam combined cycle power generation system. Meanwhile,the fuel gas from the gas turbine is used to heat the gaseous heat carrier. The system is simulated with Aspen Plus,and the balance of energy and exergy is analyzed with the simulated data. The results show that the total energy efficiency and exergy efficiency of the system reach 58.23% and 60.18% respectively,which is much higher than the original system. Furthermore,the energy efficiency and exergy efficiency of the main units in the modified system are both higher than 60%. Further analysis suggests that the increase in mass fraction of the oil shale for retorting can improve the yield of liquid fuel of the system effectively. Besides,although the electricity output of the system is reduced,the total exergy efficiency will increase obviously.
