Abstract:
A system for processing a syngas stream including particulate matter, a combustible gas, and acid components is disclosed. The system includes a gasifier vessel configured to produce a raw syngas stream; a gas cooling apparatus configured to cool the raw syngas stream to produce a cooled syngas stream; an HCl and particulate removal apparatus configured to produce a reduced-HCl syngas stream; a first reheat apparatus configured to produce a first reheated syngas stream; a COS and HCN hydrolysis apparatus configured to produce a hydrolyzed syngas stream; an H2S removal apparatus configured to produce a reduced-H2S syngas stream; a second reheat apparatus configured to produce a second reheated syngas stream; an activated carbon bed apparatus configured to produce a polished syngas stream; and a compression and intercooling apparatus configured to compress and cool the polished syngas stream to produce a clean syngas stream.
Abstract:
An uptake apparatus is arranged to extract a stream of off-gas containing carbon monoxide from a process vessel. At least one gas conditioning train receives and conditions the stream. An outlet expels at least a portion of the stream. A portion of the stream is separated to form a recycle stream. An eductor apparatus combines the stream with the recycle stream, to decrease the temperature and increase the static pressure of the stream. The stream is maintained at a positive gauge pressure.
