4. Industrial reactor technology and operation
4.1 Hydrodynamics
As the empty-barrel gas velocity increases (at constant gas composi-tion), the amount of SO2 that presents itself to the catalyst per unit time increases and consequently the conversion percentage decreases.
In practice, the gas velocity in industrial reactors is between 0.3 and 0.5 Nm3.m–2.s–1
