Show Remove sulfer from coal Did you ever hear of anyone washing coal? Through proper washing, it is possible possi-ble to remove as much as 25 percent of the sulfur from coal. In some cases, that's enough for a customer to burn coal and still meet air-quality requirements, re-quirements, reports Conoco Inc. At its new research laboratory in Library, Pa., the energy company is striving to cut sulfur content even further fur-ther to make coal-burning more environmentally en-vironmentally acceptable. The lab is the centerpiece of Conoco's Coal Technology Center, where scientists tackle many of the problems that inhibit in-hibit the burning of coal. For instance, a one-of-a-kind combustion com-bustion testing unit burns various coals under conditions simulating major ma-jor industrial or electric utility furnaces. fur-naces. Data such as fuel charaeterists, burner efficiency, emissions and ash behavior derived from the test com-bustor com-bustor help customers choose coals with greater confidence. The Center, staffed by 100 scientists, also houses analytical, exploratory and advanced chemistry laboratories and other research technology that will help realize coal's full potential as & basic energy source. The Center constitutes a state-of-the-art evolvement of 35 years of research activity by Conoco and its subsidiary, Consolidation Coal Company. |
