A method for discharging the dust that occurs from pressurized gasification, using a dust precipitator having at least one discharge container assigned to it, is supposed to be configured in such a manner that nitrogen introduction into the raw gas is minimized or completely avoided, in order to free subsequent chemical syntheses from introduction of nitrogen, if at all possible, right from the start. This is achieved in that filter elements are positioned in the dust precipitator, which elements are back-flushed by means of a gas that contains carbon dioxide or pure CO2 gas. |
