  • Publication number: 20240327216
    Abstract: The present invention relates to a process and plant for producing a hydrogen- and carbon oxides-having synthesis gas by partial oxidation of a carbonaceous feedstock having nitrogen compounds. The invention takes advantage of the different solubility of NH3 and CO2 as the synthesis gas stream is cooled. Water is condensed continuously throughout the cooling of the synthesis gas stream. NH3 preferentially dissolves or condenses into the liquid phase during cooling, but at relatively high temperatures, above about 80 to 100° C. Further condensation at lower temperatures then preferentially dissolves or condenses CO2 into the liquid phase. Thus, the formation of ammonium salts during cooling of the synthesis gas is prevented.

  • Patent number: 11912576
    Abstract: An integrated process for producing a purified and converted synthesis gas and a corresponding plant including initially converting in a synthesis gas generation stage a carbon-containing input material into a raw synthesis gas which in a subsequent CO conversion zone is altered in respect of its H2/CO ratio and finally sent to a gas scrubbing zone operating according to a physical gas scrubbing process with methanol as the absorption medium in which the content of unwanted gas constituents, in particular of acidic gas constituents, in the synthesis gas is reduced.

  • Publication number: 20220315434
    Abstract: What is proposed is a process and a plant for parallel production of methanol and ammonia by heterogeneously catalyzed reaction of hydrogen and carbon oxides on the one hand and hydrogen and nitrogen on the other hand. This includes producing a raw synthesis gas stream and dividing it into two portions. A first raw synthesis gas substream is used as input for a methanol synthesis to obtain raw methanol and a methanol synthesis purge stream. A second raw synthesis gas substream is subjected to a CO conversion, a carbon dioxide separation and a liquid nitrogen scrubbing and then sent to an ammonia synthesis. According to the invention at least a portion of the methanol synthesis purge stream is sent to the ammonia synthesis and at least one substream obtained from the second raw synthesis gas substream is passed to the methanol synthesis.

  • Publication number: 20210159741
    Abstract: The disclosure relates to a stator for an electric machine. The stator includes a stator yoke ring for receiving stator coils, characterized by: at least one stator coil carrier unit for receiving coil windings, which is configured to be plugged detachably—as a whole or with a first coil body element—on the stator yoke ring in the radial direction. The disclosure also relates to an electric machine and an electric or hybrid-electric aircraft. The disclosure further relates to a method for producing a stator.

  • Publication number: 20210091610
    Abstract: The disclosure relates to a stator tooth arrangement for a stator of an electric machine. The stator tooth arrangement includes a multiplicity of individual teeth, wherein the teeth are arranged in series when viewed in a tangential direction. Individual teeth of the stator tooth arrangement arranged adjacent to one another are connected positively to one another at their tooth roots by a connecting device of the stator tooth arrangement, with the result that, even under considerable radial loading, (e.g., shrink-fitting in the context of the production process of the machine), the stator tooth arrangement retains its very largely round shape.
