Background

The carbon monoxide transformation is an important component of the coal gasification process, and the carbon monoxide in the raw coal gas reacts with steam at a certain temperature in a transformation section under the action of a catalyst to generate carbon dioxide and hydrogen. In order to drive the shift reaction in favor of hydrogen generation, the steam requirement in the shift reaction is excessive and a large amount of condensate is produced in the shift process. The main impurities in the condensate are ammonia, hydrogen sulfide and carbon dioxide. These impurities are typically removed by steam stripping and the purified condensate is returned to the upstream gasification unit for reuse.
