A plant for synthesis of ammonia, comprising:
- a reformer for converting a hydrocarbon into hydrogen;
- a converter for converting hydrogen and nitrogen into ammonia, wherein the converter is integrated into a recirculation loop, wherein a first carbon dioxide separator is arranged between the reformer and the recirculation loop, and wherein the recirculation loop includes an ammonia separator;
- a further hydrogen source, wherein the further hydrogen source is connected to the recirculation loop in such a way that hydrogen is supplied to the recirculation loop;
- and
- a combustion apparatus, wherein the combustion apparatus is connected to a second carbon dioxide separator, wherein the second carbon dioxide separator is connected to the recirculation loop in such a way that nitrogen is supplied to the recirculation loop.
A process for expanding a capacity of an existing plant to include a further hydrogen source, wherein the further hydrogen source is connected to a recirculation loop in such a way that hydrogen is supplied to the recirculation loop, wherein a burner side of a primary reformer is connected to a secondary reformer.
A process for expanding a capacity of an existing plant, comprising:
