Advanced exergy analysis of an oil shale retorting process

摘要

Fushun-type process is the most common method of oil shale retorting used in China. The process is, however, characterized by poor thermodynamic performance. While conventional exergy analysis is able to quantitatively determine exergy destruction in a system, identification of the sources of the exergy destruction, and thus identification of areas with the greatest potential for efficiency improvement, requires advanced exergy analysis. In this paper, an advanced exergy analysis is applied to evaluate the performance of a Fushun-type oil shale retorting process.
