“…Mass transfer characteristics of various reactor configurations have compared by many researchers (Bredwell and Worden, 1998;Cowger et al, 1992;Jones, 2007;Klasson et al, 1990b;Klasson et al, 1991;Klasson et al, 1993a;Munasinghe and Khanal, 2010b;Munasinghe and Khanal, 2014;Orgill et al, 2013;Riggs and Heindel, 2006;Shen et al, 2014a;Yasin et al, 2014). In a STR, the mass transfer coefficient can be increased by increasing 268-280.…”
