IGCC Technology — Bituminous Coal IGCC With and Without CCS
Six Integrated Gasifi cation Combined-Cycle (IGCC) power plant confi gurations operating on bituminous coal were evaluated and the results are presented in this summary sheet. All cases were analyzed on the same basis, using a consistent set of assumptions and analytical tools. Each gasifi er type was assessed with and without carbon capture and sequestration (CCS). The individual confi guratio...
متن کاملOccupational health aspects of quartz in bituminous coal fly ash in Israel 2009
Quartz (α-quartz), is the most common crystalline silica polymorph in nature and is the only polymorph found in significant concentrations in coal and in coal ash. Since exposure to quartz is liable to cause lung diseases, it is very important to know the concentration of biologically active quartz in respirable particles in order to evaluate their effect on the workers in contact with them. Th...
متن کاملAutotrophic bacteria and the formation of acid in bituminous coal mines.
The passage of water through certain bituminous coal mines results in a solution which is extremely acid in reaction because of its high content of ferrous sulfate, some aluminum sulfate, and lesser amounts of manganese sulfate. The ferrous iron is subsequently rapidly oxidized to the ferric state by an autotrophic bacterium. Autotrophic bacteria have also been implicated in the formation of th...

متن کاملMapping and Prediction of Coal Workers’ Pneumoconiosis with Bioavailable Iron Content in the Bituminous Coals
Based on the first National Study of Coal Workers' Pneumoconiosis (CWP) and the U.S. Geological Survey database of coal quality, we show that the prevalence of CWP in seven coal mine regions correlates with levels of bioavailable iron (BAI) in the coals from that particular region (correlation coefficient r = 0.94, p < 0.0015). CWP prevalence is also correlated with contents of pyritic sulfur (...
