In a gas-liquid spouted vessel, where power is supplied from a pump to water and gas is introduced at a nozzle attached at the bottom of the vessel, gas bubbles are finely broken at the nozzle and dispersed to the vessel. Gas hold-up in the gas-liquid spouted vessel rapidly increases with increasing liquid flow rate and easily exceeds twice the gas hold-up in the aerated tower of the same gas flow rate with no liquid flow, though co-current liquid flow gives zero or negative effect on gas hold-up in the aerated tower. Effect of liquid flow rate, gas flow rate, nozzle to vessel diameter ratio and nozzle length one ffective spouting of gas bubbles were studied experimentally. Ways are also considered to scale up the gas-liquid spouted vessel.
