A Novel Technique based on Coal Gasification Integrated with Chemical Looping Air Separation
Author(s): Junming Fan and Lin ZhuJunming Fan and Lin Zhu
To reduce the oxygen production cost in the coal gasification process and to utilize the CO2 , this study presents a novel technique based on coal gasification integrated with chemical looping air separation (CLAS) by thermodynamic methods. CLAS offers an advantage over the other mature technologies in that it can significantly reduce its capital cost with about less than 40-60% operating costs of conventional oxygen production technologies, while recycling CO2 separated from gasification gas by CCS could not only promote oxygen production (oxygen uncoupling) of CLAS, but also enhance the coal gasification process by boudouard reaction. The thermodynamic performances, as the conversion of metal oxides (Mn2 O3 /Mn3 O4 ) during oxidation and reduction process, gasification gaseous compositions and cold gas efficiency (η) were the main subject of focus. The effects of three key vari.. View More»
