Abstract: Air-blown IGCC systems with hot fuel gas clean-up are investigated. In detail, the gas clean-up station consists of two reactors: in the first, the raw syngas exiting the gasifier and passed through high-temperature syngas coolers is desulfurized by means of a zinc oxide-based sorbent, whereas in the second the sulfided sorbent is duly regenerated. The hot fuel gas clean-up station releases H2S-free syngas, which is ready to fuel the combustion turbine after hot gas filtration, and a SO2-laden stream, which is successively treated in a wet scrubber.
