Title: A PROCESS AND RELATING APPARATUS TO MAKE PURE HYDROGEN FROM A SYNGAS ORIGINATED FROM WASTES GASIFICATION
Abstract:
A raw syngas coming from HT gasification of organic wastes, once cooled in a proper heat recovery boiler or in a quencher is treated in a scrubbing section where, by adding an acidic solution followed by alkaline solution and by a WESP, particulate and chlorine compounds are removed and the syngas is ready for conversion, after its compression. In the conversion step CO is converted into C02 and H2 by adding steam; H2S is reduced to sulphur in a solid form, C02 is removed via cryogenic unit or an amine unit and pure H2 is produced.
