Achieving absolute sustainability across integrated industrial networks-a case study on the ammonia process
Within the current global climate, precedence has been set on achieving greater sustainable development within process industries. The ammonia process (BAU case) has been labelled as a significant greenhouse gas (GHG) producer-mainly due to high energy demand and CO2 emissions. This places the proce...

Within the current global climate, precedence has been set on achieving greater sustainable development within process industries. The ammonia process (BAU case) has been labelled as a significant greenhouse gas (GHG) producer-mainly due to high energy demand and CO2 emissions. This places the process under substantial scrutiny in terms of its climate change impacts and thus, provides a strong case study for viable transition towards greater sustainable operations. Here we examine, for the first time, sustainable eco-park designs for the diversification of the ammonia industry utilizing industrial symbiosis. The network considers several carbon capture and utilization (CCU) applications as well as ammonia (NH3) integration to produce the following downstream products: NH3, urea, Urea Ammonium Nitrate (UAN), Melamine (Mel) and Methanol (MeOH). Our results demonstrate improved energy efficiency with the inclusion of MeOH while UAN decreases net energy demand. Economically, the incorporation of MeOH gave attractive returns on investment due to increased productivity.
