Rotating　packed　bed　(RPB)　has　been　widely　noted　for　its　good　mass　transfer　performance　and　tangible　size　savings,　and　its　advantages　are　especially　obvious　in　space-intensive　scenarios,　such　as　purification　of　natural　gas　on　offshore　platforms.　Liquid　maldistribution　in　RPBs　has　a　serious　impact　on　mass　transfer　performance.　However,　it　is　difficult　to　accurately　obtain　and　predict　the　liquid　flow　characteristics　and　liquid　distribution　in　RPBs　by　experimental　methods.　Therefore,　the　liquid　flow　characteristics　and　liquid　distribution　analysis　of　multi-nozzle　RPBs　based　on　computational　fluid　dynamics　(CFD)　models　is　performed　in　this　paper.　The　simulation　results　indicate　that　increasing　of　the　number　of　nozzles　and　nozzle　width　at　two　different　rotational　speeds　increases　the　liquid　holdup　and　decreases　the　degree　of　liquid　dispersion.　In　addition,　a　liquid　maldistribution　index　within　RPBs　is　proposed　and　investigated.　The　circumferential　distribution　of　the　liquid　becomes　uniform　as　the　number　of　nozzles　increase,　but　the　uniformity　gets　worse　as　the　width　of　nozzle　increases,　under　the　same　total　liquid　flow　rate.　The　more　the　number　of　nozzles,　the　more　uniform　the　overall　liquid　distribution;　on　the　contrary,　the　larger　the　nozzle　width,　the　more　uneven　the　overall　liquid　distribution.　©　2020　Elsevier　B.V.
