Title:
CARBON-BASED FUEL GASIFICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/246561
Kind Code:
A1
Abstract:
A water spray apparatus 3 sprays water over product gas on a downstream side of a gasifier 1. A dedusting device 4 removes unreacted coal from the product gas on a downstream side of the water spray apparatus 3. A first washing tower 5 removes halogen in the product gas on a downstream side of the dedusting device 4. A shift reactor 6 converts a water vapor and carbon monoxide in the product gas into hydrogen and carbon dioxide by the shift reaction on a downstream side of the first washing tower 5. A second washing tower 7 removes ammonia from the product gas on a downstream side of the shift reactor 6. An absorption tower 8 removes hydrogen sulfide and carbon dioxide from the product gas on a downstream side of the second washing tower 7. A drained water supply pipe 9 supplies drained water from the second washing tower 7 to the water spray apparatus 3. The water spray apparatus 3 sprays the drained water supplied from the drained water supply pipe 9.
