提出了一种基于先进经济性分析的油页岩干馏工艺评价与优化框架。该方法旨在帮助识别油页岩干馏过程中能量转换系统的改进潜力。通过对抚顺型油页岩干馏过程的分析，说明了该框架的应用。结果表明，考虑的OSR工艺的总(火用)损失率为442.62兆瓦，其中54.60%是可避免的。OSR工艺的总火用成本和总可避免成本分别为323.08×106元/年和115.51×106元/年，即OSR工艺的改进潜力为35.75%。研究发现，蒸馏塔是OSR工艺中最有潜力降低(火用)销毁成本的部件。优化后，OSR流程六组分的单位产品(火用)成本降低了6.93%~11.28%。单位产品总成本降低5.62%。总可避免成本降低17.03%，火用效率提高2.41%。
A framework based on advanced exergoeconomic analysis is proposed for evaluation and optimization of oil shale retorting processes. The proposed approach aims to facilitate identification of the improvement potential of energy conversion systems in oil shale retorting. A Fushun-type OSR (oil shale retorting) process is analyzed to illustrate the application of the proposed framework. The results indicate that the total exergy destruction rate of the OSR process under consideration is 442.62 MW, of which 54.60% is avoidable. The total exergy cost and total avoidable cost of the OSR process are 323.08 × 106CNY/y and 115.51 × 106CNY/y, i.e., the improvement potential of the OSR process is 35.75%. The retort is found to be the component of the OSR process having the greatest potential for decrease of exergy destruction cost. Following optimization, the cost per exergy unit of product of the six components of the OSR process decreases by 6.93%–11.28%. The total cost per exergy unit of product is reduced by 5.62%. The total avoidable cost is reduced by 17.03% and the exergy efficiency increased by 2.41%.
