Abstract
Official abstract text for this publication.
The present disclosure relates to an ammonia plant, wherein the ammonia plant comprises a converter, a first heat exchanger, and a removal apparatus. The converter and the first heat exchanger are connected to one another via a product gas connection in such a way that the ammonia synthesis product gas is guided out of the converter via the first heat exchanger to the removal apparatus. The removal apparatus and the converter are connected to one another via a reactant gas connection in such a way that the circulation gas is guided from the removal apparatus to the converter. The ammonia plant comprises a hydrogen feed that is connected to the converter via a second heat exchanger. The ammonia plant comprises a first electric heater and a steam turbine. The first electric heater is connected to the converter or to the steam turbine.
First claim
Opening claim text (preview).
What is claimed is: 1. An ammonia plant comprising: a converter; a first heat exchanger; a second heat exchanger; a removal apparatus; a product gas connection that connects the converter and the first heat exchanger in such a way that an ammonia synthesis product gas is guided out of the converter via the first heat exchanger to the removal apparatus; a reactant gas connection that connects the removal apparatus and the converter in such a way that a circulation gas is guided from the removal apparatus to the converter; a hydrogen feed connected to the converter via the second heat exchanger; and a first electric heater, wherein the ammonia plant comprises a steam turbine, wherein the first electric heater is connected to one of the converter and the steam turbine. 2. The ammonia plant as claimed in claim 1 , wherein the first heat exchanger is connected to the first electric heater in such a way that the water vapor generated in the first heat exchanger is guided into the first electric heater. 3. The ammonia plant as claimed in claim 1 wherein the second heat exchanger is connected to the converter in such a way that the reactant gas stream is guided from the second heat exchanger into the converter in a switchable manner one of directly and via the first electric heater. 4. The ammonia plant as claimed in claim 1 wherein the steam turbine is connected to a generator for power generation. 5. The ammonia plant as claimed in claim 1 , wherein the steam turbine is connected to a compressor. 6. The ammonia plant of claim 1 wherein the first electric heater is connected to the converter. 7. The ammonia plant of claim 1 wherein the first electric heater is connected to the steam turbine. 8. A process for starting up and operating an ammonia plant as claimed in claim 1 , the process comprising: during start-up, heating, via the first electric heater, the reactant stream flowing to the converter, and after start-up, in regular operation, superheating, via the first electric heater, steam from the first heat exchanger and conducting the superheated water vapor to the steam turbine.
