Compact Course:
GASIFICATION PROCESSES
6 th – 9 th June 2011
Course description:
The compact course “Gasification processes” is designed to provide a deeper insight into
gasification technologies and related issues. Within four days a broad survey on gasification
processes will be given. Starting with fuel preparation and a general overview on gasification
processes the following part includes gasification technologies in detail. Fixed bed, fluidised
bed and entrained flow gasification technologies will be explained combined with some field
trips to get better impressions. Ash behaviour, warm gas cleaning and economics of IGCC will
be explained by our two guest speakers from the Energy & Environmental Research Institute
in the United States. Finally, some modelling aspects complete the course programme.
Target group:
The course is directed toward technical personnel who are interested in increasing the depth
of their knowledge in gasification processes and technologies as well as in refreshing one’s
knowledge in a broad spectrum. The course is also well suited as advanced training course to
the short course “Fundamentals of gasification processes” that will be held in April 2011.
Some previous knowledge in the field of gasification processes is desirable.
