Annotation:

In recent years, there has been observed a steady increase of demand for ammonia production, caused by its crucial role in agriculture (fertilizers), industry, and its potential of being used in green energy (as a hydrogen carrier). The main market drivers include growing food demand, the transition to a low-carbon economy, and geopolitical changes of supply chains. The rising market demand for ammonia necessitates the construction of new production facilities and technical upgrade of the existing plants in order to increase output. However, the primary limiting factor of enhancing ammonia unit productivity is the syngas compressor, which represents expensive and complex equipment. The authors of the article present technical solutions for increasing ammonia unit capacity while maintaining the existing syngas compressor. Three process schemes that were compared in terms of productivity increase are presented. Based on the comparison results, the most efficient scheme has been identified.
