This was obtained over 39 days for a gas flow range between 0.12 and 0.72 m3 hâ1 and a resulting toluene inlet concentration range of 0.71â0.51 g mâ3, respectively. During the first 25 days, the greatest EC was in the first stage (55 g mâ3 hâ1), contrasting with the low EC obtained in the other two stages.
