Biomass Based Sustainable Ammonia Production
Presentation

The renewable ammonia production is gaining attention nowadays. Current production processes use as raw material, predominantly, natural gas or coal. Therefore, large amounts of greenhouse carbon dioxide are released in the production process. Different alternatives for a sustainable path to produce ammonia have been analysed. One alternative is producing hydrogen through electrolysis, nitrogen by air separation and then produce ammonia via Haber Bosch process (Sánchez & Martín, 2018). An interesting feature of this process is the possibility of integrating renewable energy sources in the ammonia production. Another technology is the electrochemical ammonia production (Bicer & Dincer, 2017). The ammonia synthesis…

Scale up and Scale Down Issues of Renewable Ammonia Plants: Towards Modular Design
Presentation

Renewable sources of energy such as biomass, solar, wind or geothermal just to mention some of the most widely extended are characterized by a highly distributed production across regions (EPA, 2017). Total renewable energy available is more than enough to provide for society needs, but the traditional production paradigm is changing. Economies of scale have featured current industry and its infrastructures based on large production complexes (i.e Dow, Exxonmobil or BASF hubs). The well-known six tenths rule has extensively been used in the chemical industry to scale up or down the cost of technologies. This rule is suitable for large…
