Process for producing low-carbon ammonia from natural gas

1:

• A method for producing ammonia from natural gas that comprises heating the natural gas and steam and subjecting them to primary reforming, subjecting resulting converted gas to secondary reforming that operates on a mixture of steam, air, and oxygen, and then sending resulting converted gas to carbon oxide conversion, removing carbon dioxide from resulting syngas, methanating purified syngas, then synthesizing and recovering ammonia, which is exported as a finished product, while utilizing purge gas downstream the ammonia recovery as a fuel to increase temperature of the natural gas and steam, wherein, after the methanation, the syngas is compressed and sent to the ammonia synthesis, downstream the ammonia recovery purge gas pressure is reduced through expansion, the ammonia recovery uses a heating medium cooled as a result of the purge gas expansion, and ammonia condensed from the purge gas during expansion is exported as a finished product.
