PENERAPAN AMES PROCESS UNTUK PENURUNAN KADAR SULFIN BATURARA MELALUI PROSES HOT WATER DRYING
Sulfur reduction for high sulfur coal content can be carried through out the Hot Water Drying with sodium carbonate solution and oxygen gas addition. These process can be reduced the total sulfur up to maximum 47.01%, pyrite sulfur 57.32%, sulfate sulfur 70.57% and the moisture content lowered down...

| Summary: | Sulfur reduction for high sulfur coal content can be carried through out the Hot Water Drying with sodium carbonate solution and oxygen gas addition. These process can be reduced the total sulfur up to maximum 47.01%, pyrite sulfur 57.32%, sulfate sulfur 70.57% and the moisture content lowered down to 2.04%. But organic sulfur increased to as much as 16.6%, if that process operated at temperature 300°C for 60 minute, those change are not influenced by coal particle size. The other effect of sodium carbonate and the oxygen addition are increasing the quality of high sulfur low rank coal with increased the calorific value, carbon content, and HGI, respectively. Nevertheless, sodium oxide in the coal ash was increased, so that the coal yield had severe in fouling type, although potassium oxide is lowered, in that condition. |
