  • Publication number: 20240246830
    Abstract: A method of producing ammonia includes heating, with a start-up oven, a first synthesis gas for a first ammonia synthesis in a first reactor; transferring the heated first synthesis gas to the first reactor for initiating a chemical reaction; heating, with the start-up oven, a second synthesis gas for a second ammonia synthesis in a second reactor; and transferring the heated second synthesis gas to the second reactor for initiating a chemical reaction, wherein a high-pressure synthesis of ammonia is carried out in the first reactor and a low-pressure synthesis of ammonia is carried out in the second reactor at a process pressure which is lower than the process pressure in the first reactor.

  • Patent number: 11939226
    Abstract: An ammonia plant having a first and second reactor and a start-up oven having at least one first heat exchanger. The first reactor operates under a higher internal pressure than the second reactor. The start-up oven is connected via a piping system for at least one synthesis gas to the first and second reactor. Ammonia is produced by heating synthesis gas in the start-up oven and transferring the heated synthesis gas to the first reactor for initiating the chemical reaction. Synthesis gas is heated with the same start-up oven and is transferred to the second reactor for initiating the chemical reaction, wherein high-pressure synthesis of ammonia occurs in the first reactor and low-pressure synthesis of ammonia occurs in the second reactor at a lower process pressure than in the first reactor.
