Working up and conducting fuel gas produced from gasification - by cooling crude gas from generator, treating in scrubber,cooling, and re-evaluating gas

摘要

Working up and conditioning fuel gas from the gasification of carbonaceous products including waste and residues comprises: (a) cooling the crude gas exiting the gas generator to max. 300 (pref. 100-200) deg. C; (b) treating the cooled gas in a scrubber with an organic coolant to remove dust and tar components; (c) cooling the gas by vaporising the organic coolant to 20-50 deg. C; and (d) re-evaluating the gas by the vaporised amts. of coolant.
