【摘要】：基于油页岩气体热载体干馏工艺构建了一种油页岩综合利用系统,将干馏过程中产生的半焦与小颗粒油页岩混合后气化,制得合成气与多余干馏气一并经水煤气变换后进行费-托合成,费-托合成剩余的可燃气体送入燃气-蒸汽联合循环发电系统,实现油-电联产,采用此综合利用系统,可大幅提高液体燃料产量,达到原有干馏系统的1.4倍。利用Aspen Plus软件对所构建的油页岩综合利用系统进行建模,经计算,综合利用系统的一次能量利用效率达到61.79%。进一步模拟分析表明,增加油页岩干馏比例和干馏-气化混合气制油比例,都可以有效提高系统液体燃料的产量,虽然系统电能输出会有所下降,但系统总能效会随着液体燃料产量的增长有显著提升。
[Abstract]:A comprehensive utilization system of oil shale was constructed based on the oil shale gas heat carrier distillation process. The semi-coke produced in the distillation process was mixed with small grain oil shale and then gasified. The synthesis gas and the excess distillate gas were synthesized by the water gas transformation, the remaining combustible gas was fed into the gas-steam combined cycle power generation system, and the oil-electricity cogeneration was realized, and the comprehensive utilization system was adopted. The liquid fuel production can be greatly increased to 1.4 times of the original distillation system. The oil shale comprehensive utilization system is modeled by Aspen Plus software. The primary energy utilization efficiency of the comprehensive utilization system is 61.79 by calculation. Further simulation analysis shows that increasing the proportion of oil shale retorting and distillation-gasification mixture can effectively increase the production of liquid fuel in the system, although the power output of the system will decrease. But the total energy efficiency of the system will increase significantly with the increase of liquid fuel production.
