Application of Supercritical Water Oxidation Technology in Energy Transformation

介绍了超临界水氧化在能量转化领域的研究现状,阐述了超临界水氧化技术在高浓有机废水联产蒸汽、低浓有机废水能量耦合、有机固体废弃物能量回收以及稠油热采等4个方面的发展和应用,并展望了超临界水氧化技术在能量转化领域的发展趋势,认为应加强对能量转化机理的研究、过程能流分析以及换热介质材料,从能量品位的角度分析操作参数对火用损的影响,以及调整多种耦合方式对利用效率的影响,探究转化过程中火用损和焓损的深层次原因;通过对反应装置、换热介质材料的研究,避免热量损失以及转化过程中不必要的火用损,以此提升能量转化效率。

The current research status of supercritical water oxidation in energy transformation were summarized, the development and application of supercritical water oxidation in energy transformation, such as high concentration organic wastewater treatment for steam coproduction, low concentration organic wastewater treatment for energy coupling, organic solid waste treatment for energy recovery and thickened oil thermal recovery, were systematically introduced, the development tendency were expected. It was considered that the study of energy conversion mechanism, process energy flow analysis and heat transfer medium materials should be strengthened, the influence of operation parameters on exergy loss should be analyzed from the energy grade point, and the influence of various coupling modes on utilization efficiency should be adjusted to explore the underlying causes of exergy loss and enthalpy loss in the process of transformation. The heat loss and exergy loss should be avoid in transformation process by the study of reaction equipment and heat transferring medium material, to improve the energy exchange efficiency.
