The more complex the gasification process, the more complex is the wastewaterprocessing scheme. On this basis, the movingbed technologies (Lurgi and British Gas/Lurgi) typically require the most complex wastewaterprocessing scheme, while the entrainedflow gasifiers require a relatively simple processing scheme. In either case, wastewater ...

British Gas/Lurgi Gasifier. reduce steam consumption and consequent gas condensate production. Notably, the BGL gasifier reaches much higher temperatures (over 3600°F or ~2000°C) at the bottom zone of the gasifier, which melts ash to slag. In operation, a coal mixture (coarse coal, fines, briquettes, and flux) is introduced at the top of the ...

3. Introduction 3 Gasification is a technological process that can convert any carbonaceous raw material such as coal into fuel gas, also known as synthesis gas (syngas). Syngas is Composed primarily of the colorless, odorless, highly flammable gases carbon monoxide (CO) and hydrogen (H2). Gasification occurs in a gasifier, generally a high temperature/pressure vessel where oxygen and steam ...
