It is notable that over the past decade, proven reserves of natural gas have dramatically increased as higher prices and advances in technology have turned previously unrecoverable resources into major sources of domestic production. Moreover, the decline in crude oil reserves has significantly slowed over the past decade. Therefore, there would be an end to the conventional hydrocarbon resourc...

The Development Plan of Taranto port (S. Italy) predicts the dredging of approx.20 Mt sediments, ≥10% of which are polluted. By appointment of Italian Environment Ministry, a detailed experimental investigation was carried out at laboratory and pilot-scale levels on the best available techniques to reclaim the polluted sediment so to reuse it in a technic and cost effective manner. A short pre-...

subject analysis of the potential of spontaneous combustion in coal layers with analytical and numerical methods has been always considered as a difficult task because of the complexity of the coal behavior and the number of factors influencing it. empirical methods, due to accounting for certain and specific factors, have not accuracy and efficiency for all positions. the rock engineering syst...

A project on co-firing in large-scale power plants burning coal is currently funded by the European Commission. It is called COPOWER. The project involves 10 organisations from 6 countries. The project involves combustion studies over the full spectrum of equipment size, ranging from small laboratory-scale reactors and pilot plants, to investigate fundamentals and operating parameters, to provi...

China's coal-dominated energy structure will not change in a short time. In order to implement the relevant national policies on conservation and emission reduction, it is good response adopt circulating fluidized bed boilers coal-fired power stations. Circulating boiler adopts combustion, which has high reliability utilization rate because of its special combustion mode particle recycling devi...

Abstract Coal-conversion technologies, although used ubiquitously, are often discredited due to high pollutant emissions, thereby emphasizing a dire need optimize the combustion process. The co-firing of coal/biomass in fluidized bed reactor has been an efficient way pollutants emission. Herein, new model designed Aspen Plus® simultaneously include detailed reaction kinetics, volatile compositi...

Coal gasification wastewater has complex pollutant components and high COD value, contains a variety of toxic harmful substances. The treatment coal always been one the important problems in development industry China. In this paper, aiming at removal fine particle pollution wastewater, sand filtration method was used to explore changes parameters such as solid content removal, separation accur...
