Definitions
- liquid redox processes are particularly suitable.
- This liquid redox process is based on the concept of reactive absorption, in this case a combination of absorption and oxidation.
- the hydrogen sulfide contained in the gas is chemically or physically bound to an active substance of the washing medium.
- Gas stream must be compressed in order to be fed into the combustion chamber can.
- this process variant compared to a regeneration at atmospheric pressure, a much smaller air volume flow has to be compressed than if the pressure increase necessary for the regeneration had to be achieved by a separate compressor.
- this embodiment also represents a particularly preferred use of the exhaust air, since only an additional connection piece is required for this purpose.
- emissions can be reduced because the potentially contaminated exhaust air from the regeneration stage passes through the combustion process of the gas turbine, rather than, for example, simply being blown out.
- the separation of the elemental sulfur contained in the washing medium is desired.
- at least one partial stream of the washing medium, which in addition to the reduced catalyst just contains the precipitated elemental sulfur, is preferably separated off.
- the separation of the precipitated sulfur at different points is possible.
- the partial flow can take place, for example, either before the expansion of the washing medium in the flash container or else afterwards.
- it is preferable to remove so much sulfur that the concentration of the precipitated sulfur in the washing medium after separation is about 5%.
- a removal line for removing a partial flow of the washing medium is preferably included.
- the extraction line can in principle be connected to different positions of the device, wherein a removal from the designed as a flash tank expansion stage is preferred. Accordingly, the extraction line is expediently connected to the expansion stage. In this way, a part of the dation of hydrogen sulfide precipitated elemental sulfur are separated from the washing medium.
- the preferred concentration of precipitated sulfur remaining in the wash medium after separation is about 5%.
