Abstract
Gasification processes come with great challenges regardless of the scale. Pilot-scale facilities encounter various problems, such as low conversion efficiencies or tar removal, which usually need significant trial and error, time, and finances to solve. Using data generated in pilot-scale facilities to model and simulate further developments in demonstration and commercial-scale plants is a well-known path that researchers and technology developers employ to reduce the risks of scale-up. In this chapter, few examples of pilot-scale gasification units are discussed, some of which are currently successful demonstration or commercial-scale plants. The chapter also describes some less successful examples and projects which are still in early development stages.
