Definitions
- the present invention relates to a method for producing (co-production) carboxylic acid (such as acetic acid) and ammonia.
- Ammonia is obtained by a reaction between hydrogen and nitrogen, and synthesis gas is usually used as a hydrogen source for this reaction.
- the synthesis gas contains carbon monoxide in addition to hydrogen, and the carbon monoxide and water are subjected to a so-called water gas shift reaction and used for ammonia production.
- Such a shift reaction can use a large amount of hydrogen in the production of ammonia, but a large amount of carbon dioxide is by-produced by the shift reaction.

Therefore, this method does not focus on carbon dioxide produced as a by-product in the shift reaction in ammonia production, but can use only a small amount of carbon dioxide contained in the synthesis gas for synthesis of the synthesis gas. There is an upper limit to the amount of return to the synthesis gas.
- this method uses natural gas as a raw material for methanol synthesis, and requires a synthesis gas having a high hydrogen content. Therefore, a large-scale separation device or an additional separation device is required for separating a large amount of hydrogen in a later process. Furthermore, this method cannot effectively utilize oxygen separated from air used as a nitrogen source for ammonia synthesis.

Abstract
Description
なお、シフト反応ユニット10は、合成ガスシフト反応装置(反応器)を備えていればよいが、通常、シフト反応させるとともに、シフト反応後のガスから水素(合成ガスに予め含まれている水素およびシフト反応により生成した水素)を分離して供給ライン10Aに供給するための分離する装置(工程)を有している。すなわち、シフト反応後のガスには、前記のような他の成分、特に、シフト反応により副生した二酸化炭素が多量に含まれているため、水素を新たに分離する装置(工程)が必要となる。水素を分離する方法としては、前記と同様の分離法、レクチゾールプロセス、メタネータ法などを利用できる。
