Claim Text:
1. A device for treatment of crude synthesis gas from a facility for partial oxidation of fuels in an entrained flow gasifier, in which a path of the crude synthesis gas is in sequence of following stages, the device comprising: an entrained flow gasifier configured for supplying a steam-saturated crude synthesis gas, a cascade of water scrubbers receiving the steam-saturated crude synthesis gas and configured for cleaning the crude synthesis gas to remove dust particles therefrom, a mixer having a first entrance for receiving the cleaned crude synthesis gas from the water scrubbers, the mixer having a second entrance for receiving a supply of hot gas, the mixer having an exit for supplying superheated, unsaturated crude synthesis gas from the exit of the mixer; a heat exchanger having a first gas channel for receiving the crude synthesis gas from the exit of the mixer; a crude gas converting device receiving the crude synthesis gas from the heat exchanger, and an acid gas scrubber receiving the crude synthesis gas from the crude gas converting device, wherein the heat exchanger has a second gas channel for receiving the crude synthesis gas from the acid gas scrubber into the second gas channel of the heat exchanger, the second gas channel of the heat exchanger has an exit for the converted crude synthesis gas, and the mixer comprises a static mixer.
