This paper deals with the modeling and simulation of airsteam gasification of coal using Aspen Plus process simulator. The model is able to predict the gas products, tar concentration, and char yield where the prediction accuracy of the presented model has been validated against the experimental ...
University of Alberta Edmonton, AB Canada 发布日期2011 Underground coal gasification (UCG) has received renewed interest due to its potential for utilization of the vast amounts of coals available in deep underground seams and the current drive towards clean coal utilization. UCG process involves the...
Here, we present a ready-to-implement method to reduce the carbon emission of CFPPs in limited space: roof photovoltaic-assisted power generation combined with sludge co-combustion for coal-fired power generation systems (PVSCs). We also consider nonurban CFPPs with the method of roof ...
Program to discover materials suitable for service under hostile conditions obtaining in equipment for the gasification of coal and other solid fuels. Annu... Coal gasification plants are expected to have a range of hostile environments from room temperature to 2000/sup 0/F and from atmospheric ...
The "El Tremedal" Underground Coal Gasification (UCG) trial sponsored by Belgian, Spanish and United Kingdom government organisations and the European Community has conducted two gasification phases during the summer-autumn of 1997, of nine and five days duration respectively. A gas of good quality...
Pressurized coal gasification is not only the key part of the Integrated Gasification Combined Cycle (IGCC) but also the better approach to increase the gasification reaction rate and capacity of the unit gasifier. In this work, the gasification characteristics for a sub-bituminous coal with an air...
In-situ Gasification Chemical-Looping Combustion (iG-CLC) burning coal is achieving a great interest due to the possibility of using low cost oxygen carriers such as CaSO4. The Limestone Chemical LoopingCombustion process(LCL-C™) registered by Alstom Power Inc. proposes the use of a continuous...
