20100263278 | GASIFICATION REACTOR AND PROCESS FOR ENTRAINED-FLOW GASIFICATION - A process and device for the gasification of liquid or fine-grain solid fuel materials with the aid of oxygenous, gaseous gasification agents in a reactor is described. Liquid slag is separated on the walls of the reactor. The synthesis gas is generated in a first reaction chamber arranged in the upper part of the reactor and the feedstock is fed to the upper part. Liquid slag precipitates on its lateral walls, with free downflow and no solidification of the slag surface. The lower side has a hole with a slag drop-off edge, from which the generated synthesis gas can be withdrawn in downward direction and the liquid slag can drop off the edge. A second chamber which is delimited by a water film is located under the opening and used to keep the synthesis gas dry and cool. A third chamber is adjacent to the bottom of the second and fed with water to cool the synthesis gas. A water bath is adjacent the bottom of the third chamber and collects the slag particles already solidified and dropped off or those particles still in the liquid phase. The synthesis gas is withdrawn from the pressure vessel in an area below or on the side of the third chamber but in any case located above the water bath. | 10-21-2010 |

20110000779 | METHOD AND DEVICE FOR TREATMENT OF FLUID STREAMS THAT OCCUR DURING GASIFICATION - A method and a device for treating fluid streams produced during the combustion of carbon- and ash-containing fuels optimally uses the heat content contained in the system, as well as the amount of water for cooling and condensation required during recirculation of the latter. Suspension withdrawn from the mixing vessel is expanded in at least one subsequent stage during the evaporation of at least part of the water and reduction of the temperature, The vapor produced is cooled by direct contact with water and at least partially condensed out. In the device, a line between a lower section of the mixing vessel leads to a first expansion vessel that is designed as a scrubber tower, the scrubber tower being provided with a condensate collection bottom and a recirculation line towards the mixing vessel for the forming condensate, which mixing vessel is equipped with spray heads. | 01-06-2011 |

20140044601 | PROCESS FOR THE PURIFICATION OF CRUDE GAS FROM SOLIDS GASIFICATION - A process and device is provided for the generation and purification of a crude gas for synthesis gas generation from a solid carbon-containing fuel by a coal gasification reaction. The fuel is mixed with a quenching medium directly after generation to dissipate the internal energy and is then brought into contact with a compound or a sorbent in the mixing chamber or downstream of the mixing chamber such that the acidic or basic or sulphur-containing or halogen-containing constituents contained in the crude gas and originating from the gasification reaction are absorbed. A solids-separating device removes the solid or solidified constituents from the system. The sorbent can be regenerated and returned to the process such that an energy-intensive cooling of the crude gas is not required for its purification and the synthesis gas thus purified can be used in a subsequent process without any further heating. | 02-13-2014 |
