If the gas concentration is 6% too high, the SO2 in the exhaust gases cannot be properly converted; if the concentration is too low, the conversion process proceeds too slowly :(
Control the conversion temperature, the concentration and temperature of the dry absorption acid, as well as the liquid-to-vapor ratio
Control the acid temperature in the second absorption tower to be no lower than 60℃
Haste makes waste. It’s like asking someone to give birth at 6-7 months old, but expecting that the baby will be as active and lively as a full-term baby.
Rapidly increase the acid temperature in the absorption tower
