This webinar will be comprised of two presentations: Update on progress developing plasma Technology for Nitrogen Fixation by Magnus Nyvold of N2, Norway, and How green ammonia feed and state of the art N2O abatement lead to green nitric acid production by Daniel Birke, thyssenkrupp, Germany.
Update on progress developing plasma Technology for Nitrogen Fixation
Magnus Nyvold, N2, Norway
When novel methods of reactive nitrogen synthesis were invented in the early 20th century, they laid the groundwork for the coming green revolution, where a growing population was sustained by a rapidly increasing agricultural output. Consequently, the epithet of today’s nitrogen fertiliser production, the Haber-Bosch process, is considered one of the most important discoveries of the previous century. The Haber-Bosch process has been tremendously successful, in part because of how close it can operate to its theoretical efficiency limit. An achievement that depends on, and has long benefited from, fossil coal and gas. The Haber-Bosch process is therefore bound by both a theoretical limit and a dependency on fossil resources to maintain its efficiency, leaving significant improvements in the technology’s past.
Hence, one of Haber-Bosch’s precursors has gained renewed attention: the Birkeland-Eyde process. Developed by Kristian Birkeland in 1903, the process relies on electricity and air alone to generate an electric arc, in essence an air plasma, with the ability to form reactive nitrogen for fertiliser production. The process was discontinued because of its high energy consumption, but advances in plasma science have rejuvenated the concept and the plasma process is now a serious contender for the future of nitrogen fertiliser production.
N2 Applied is at the forefront of this development, working together with renowned research institutions to improve the efficiency of plasma nitrogen-fixation (which, theoretically, is lower than that of the Haber-Bosch process). The coming years will reveal more of the technology’s true potential and impact, but the current research and development indicate that the N2 process is equipped with agronomic and environmental benefits that will make it a viable alternative long before the theoretical energy efficiency of the Haber-Bosch process is surpassed.
The webinar will detail the steps of the N2 process; its potential benefits and supporting evidence, and present the six pilot N2-units currently operating on farms across Northern Europe.
How green ammonia feed and state of the art N2O abatement lead to green nitric acid production
Daniel Birke, thyssenkrupp
A growing world population and increasing wealth are the key drivers for climate change and pollution. It cannot be denied that climate change and pollution are endangering our livelihood and are becoming the biggest challenge of this century. One solution to stop climate change is the reduction of greenhouse gas emissions – in case of the fertilizer industry mainly CO2 and N2O – by following new production routes or by innovative abatement methods.
Ammonia is an essential feedstock for the production of N-fertilizer. During the first part of the webinar thyssenkrupp Industrial Solutions will present to the audience the fundamentals of the green hydrogen generation from renewable energy together with an introduction into the synthesis concept for the production of green ammonia and the associated challenges herewith.
During the second part of the webinar the fundamentals of the green nitric acid process will be presented with main focus on environmental protection as N2O and NOx reduction. Environmental protection is ensured by the EnviNOx® system, which is currently the best available technology for the tail gas treatment of a nitric acid plant. An EnviNOx® system enables nitrogen oxides emissions (nitric oxide [NO] and nitrogen dioxide [NO2]) in normal operation to be reduced to below 1 ppm by volume, with emissions of the greenhouse gas nitrous oxide (N2O) being cut by 99%.
