Too much carbon monoxide is produced by the water-coal slurry gasifier, which overloads the shift reactor – how to deal with this?
Thread Content
In the Texaco gasifier, the carbon monoxide content increases, causing the shift converter to be overburdened. Is there a good solution? How did it happen!
Check the slag port pressure difference; it’s most likely that the slag port is blocked
The design is too small; increasing the appropriate amount of converter catalyst loading can improve things
A small transformation factor is one aspect of the issue; it is also related to deviations between the operating data of the gasification furnace and its design parameters. The current approach remains to operate the gasification furnace properly
It may be that the quality of the coal has changed, resulting in an increase in the reaction temperature. Try reducing the coal slurry concentration slightly
Has the volume changed? Is it an increase in volume with more carbon monoxide, or is the volume relatively unchanged while the proportion of carbon monoxide increases? If the proportion of carbon monoxide increases, it should be similar according to the previous answers; if the overall volume of gas increases, then the load on the gasification furnace should be reduced accordingly.
