Harry Morehead charted the Siemens history on gasification starting with the Schwarze Pumpe 200 MW unit in 1984. Today there are a number of coal-to-chemicals and coal- to-syngas projects. The NCPP coal-to-polypropylene project in China is 2500 MWth. The JinCheng coal-to-ammonia project is 1000 MWth. Projects in development include Secure Energy coal-to-SNG, (1000 MWth), Summit Power (600 MW IGCC) and Sherritt/EPCOR lignite-to-hydrogen (380 MW IGCC). Syngas is cleaned in a venturi scrubber in contrast to the Conoco use of a high temperature ceramic filter. The system can handle a wide variety of fuels including biomass. Siemens offers complete services including operation and maintenance. |
