This paper presents the modeling and simulation of an industrial-scale chemical looping combustion (CLC) power plant, including all process units (reactors, flue gas treatment units, heat integration, steam cycle, CO2 compression train). A model a 525 MWth CLC plant was built using rigorous representation solid fuel oxygen carrier. Petcoke considered main interest in this study, it is compared ...

Exergy analysis is based on combined first and second laws of thermodynamics and is a useful tool to analyze the energy systems in a better and more realistic way than an energy analysis, based on the first law of thermodynamics. Combination of exergy from thermodynamics with conventional concepts from engineering economy which is referred to as thermo-economy (exergo-economy) is a valuable too...

Production performance of heavy oil deposits in Xinjiang oilfield developed by vertical-well cyclic steam stimulation (CSS) is increasingly challenged reservoir heterogeneity, which comprised original sedimental heterogeneity and steam-induced heterogeneity. In order to understand the impacts high-speed injection conformance, strategies maximize swept volume, a series experiments were designed ...

Chemical reactions between oil-sands and injected steam or condensate during cyclic stimulation (CSS), commonly used to mobilize heavy oil bitumen, result in decomposition of pre-existing minerals formation new phases including clay minerals. These changes can reduce reservoir permeability limit hydrocarbon recovery. In this study, the chemical stable isotope compositions berthierine smectitic ...

A review of the literature and discussions with plant operators has been undertaken to establish present knowledge and understanding of the chemistry of the condensates formed on steam turbines and the link to system operation. This has been supplemented by an overview of the effect of test variables on environment assisted cracking. In Section 1, steam turbine operating conditions are describe...
