Buggenum – SCGP operation capabilities Capability of load following • Gasification island: > 5% load per minute • Total IGCC with SCGP: > 3% load per minute • Limitation: Air separation unit Capability of turndown • Gasifier turndown: Down to 50% Shell Global Solutions 14
Nuon IGCC plant, clean coal technology aspects • Extremely low NOx, typically below 10 ppm • Sulphur removal efficiency over 99% • Total acidification components NOx + SO 2 : coal gas operation better than natural gas • Virtually zero emission of fly ash, chlorides and volatile heavy metals • Zero discharge: waste water reused in plant Courtesy of Nuon Shell Global Solutions 15
