GASIFICATION - THE ROUTE TO CLEAN AND EFFICIENT POWER-GENERATION WITHCOAL

Future Integrated Gasification Combined Cycle (IGCC) power plants will have superior environmental performance and unmatched efficiency. The Shell Coal Gasification Process (SCGP) is a clean coal technology, wh ich can convert a wide range of coals into clean syngas for high effic iency electricity generation in an IGCC plant. SCGP flexibility has be en demonstrated for feeds ranging from bituminous coals to lignites an d petroleum coke, and the process is ideally suited for combined cycle power generation, resulting in efficiencies of 42% to 46% (LHV). In t he Netherlands, a 250 MWe coal gasification combined cycle plant based on Shell technology is being built by Demkolec, a development partner ship of the Dutch Electricity Generating Board (N. V. Sep). The plant is scheduled to start up in 1993.
