Beyond equilibrium ammonia synthesis in a membrane and heat exchange integrated microreactor: A modeling study

Ammonia Energy: Synthesis and Utilization

“…It has been reported that this so-called “absorbent-enhanced Haber-Bosch” can operate at pressures 10 times smaller than the traditional Haber-Bosch process, so it has better economics . Additionally, recent studies have shown that it is possible to improve ammonia synthesis performance by reducing the heat exchange and loop compression load, using a cascade ammonia synthesis system or a microstructured membrane reactor with reaction, cooling, and ammonia separation functions, and changing the reactor configuration from tubular to spherical axial/radial flow …”

“…29 Additionally, recent studies have shown that it is possible to improve ammonia synthesis performance by reducing the heat exchange and loop compression load, using a cascade ammonia synthesis system or a microstructured membrane reactor with reaction, cooling, and ammonia separation functions, and changing the reactor configuration from tubular to spherical axial/radial flow. 31 The production of ammonia inevitably produces a large amount of carbon dioxide. It is estimated that the production of 1 ton of ammonia will emit 3.85 tons of carbon dioxide per year, accounting for about 2.5% of global fossil fuel carbon dioxide emissions.…”
