Optimal renewable production of ammonia from water and air

[EN]n this work a production facility of ammonia has been evaluated using air and water as raw materials. Nitrogen is obtained from air separation using a Linde's double column. Hydrogen is produced from water splitting. Next, hydrogen and oxygen are purified to remove water and traces of chemi...
