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 ...
