Abstract
Provided is an ammonia synthesis system including an ammonia synthesis reactor; two or more catalyst beds; a distribution plate; a backflow prevention plate; a distribution device; and mixed gas supply lines, wherein the distribution plate has a plurality of openings formed independently of each other, and a percentage of a total region of the openings to a total region of each distribution plate is referred to as an opening ratio, wherein the opening ratio of the distribution plate is decreased toward a lower part.
Claims16
An ammonia synthesis system comprising:
- an ammonia synthesis reactor;
- two or more catalyst beds included in the ammonia synthesis reactor;
- a plurality of distribution plates with each distribution plate disposed upstream from the catalyst beds;
- a plurality of backflow prevention plates disposed downstream from each of the catalyst beds except for the catalyst bed disposed at the lowest of the catalyst beds for preventing a backflow of mixed gas;
- a plurality of distribution devices, each distribution device disposed upstream from each of the distribution plates for distributing the mixed gas to the distribution plate;
- and
- mixed gas supply lines arranged to supply the mixed gas to the respective distribution devices,
- wherein the distribution plate has a plurality of openings formed independently of each other, and
- wherein an opening ratio of the distribution plates is decreased toward a lower part.
An ammonia synthesis system comprising:
- a mixed gas supply line providing mixed gas including hydrogen generated from a process using renewable energy to an ammonia synthesis reactor;
- the ammonia synthesis reactor;
- a first and a second catalyst bed included in the ammonia synthesis reactor;
- a first distribution plate disposed upstream from the first catalyst bed;
- a second distribution plate disposed upstream from the second catalyst bed;
- a first backflow prevention plate disposed downstream from the first catalyst bed for preventing a backflow of mixed gas;
- a first distribution device disposed upstream from the first distribution plate for distributing a mixed gas feed to the first distribution plate;
- a second distribution device disposed upstream from the second distribution plate for distributing a mixed gas flow exiting the first catalyst bed to the second distribution plate;
- wherein each distribution plate has a plurality of openings, and
- wherein an opening ratio of the second distribution plate is lower than an opening ratio of the first distribution plate.
