Abstract
|
In thermal decomposition process, ammonium nitrate decomposition takes place in fluidized bed
reactor (FR) and nitrogen oxide (NOx), as an undesirable product is produced in high temperatures. In this
study, two novel configurations named membrane fluidized bed reactor (MFR) and free air membrane
fluidized bed reactor (AMFR) is proposed to reduce NOx emission. Models predictions are validated by
experimental data presented by Bhowmick et al. The results show 16% and 7% decrease in NOx
concentration in AMFR and MFR respectively, compared with FR. Reduction of NOx emission and
enhancement of ammonium nitrate conversion, demonstrate superiority of AMFR to previous
configurations.
