Remote, small-scale, 'greener' routes of ammonia production
The ICI leading concept NH 3 is a modular, small-scale, NG-based NH 3 process that has been shown to compete in terms of efficiency and the costs of the production of NH 3 with conventional, highly integrated large-scale NH 3 plants (Arkley et al., 1988). The first plant based on this technology was constructed in 1988 in U.K. and …
