A METHOD OF TREATING A SYNGAS STREAM |
摘要 |
<p>The present invention provides a method of treating a raw syngas stream and an apparatus therefor. In the method a raw syngas stream is passed to a hydrolysis unit to provide a hydrolysed syngas stream and a condensed water stream. The hydrolysed syngas stream is passed to an acid gas removal unit to separate H2S and a part of the CO2 from the hydrolysed syngas stream to provide a treated syngas stream and an acid off-gas stream. The acid off-gas stream and a sulphur dioxide-comprising stream are passed to a catalytic zone to react H2S in the acid off-gas stream with SO2 in the sulphur dioxide-comprising stream to provide an elemental sulphur stream and a catalytic zone off-gas stream.</p> |
