WEBINAR - Optimisation of the water footprint for sustainable ammonia in the fertilizer industry
As the world’s population continues to grow, so does the demand for fertilizers. Ammonia is one of the most crucial chemicals in the modern world. It is the key component in producing nitrogen-based fertilizers, which are essential for global food production. Ammonia production presents significant environmental challenges, one of which is the large amount of water required for the process.
Water does not just enter the chemical reaction as a feedstock, but is involved in various stages of ammonia production, making the overall process highly water-intensive.
This presentation goes through an overview of how ammonia is produced with a particular focus on the quantity and quality of water needed. To determine the quantity and usage of the required water, a number of ammonia production plants — where Cannon Artes has either collaborated or supplied water treatment plants — were studied. In particular, several plants with capacities ranging from 400 to 4400 tpd of ammonia produced, located in different parts of the world, were analysed.
This study allowed Cannon Artes to calculate the amount of water required for steam production, for cooling necessities, and for other uses. For each, a clear correlation has been found on the respective amount of water per ton of produced ammonia.
The study further explores an analysis of the waste streams exiting the ammonia plants with their relevant capacities and detail of possible contaminants. It then gives a hint as to how such streams can be recovered and reused to the maximum level.
With this goal in mind, the presentation suggests a general ‘water-reuse’ scheme.
As ammonia production plays a key-role in the energy transition, the presentation also analyses how carbon sequestration in ‘blue-ammonia’ and electrolyser requirements in ‘green ammonia’ are further impacting the water cycle, increasing the need for advanced water management expertise.
