Abstract (en)
[origin: WO2010086104A1] The invention relates to a method for discharging the dust arising from pressure gasification using a dust precipitator having an associated discharge container, designed such that nitrogen entry into the raw gas is minimized or completely prevented, in order to keep subsequent chemical syntheses from experiencing nitrogen entry as much as possible in advance. The aim is achieved in that the filter elements positioned in the dust precipitator are backflushed using a gas comprising carbon dioxide or pure CO2 gas.
