A suspended mass transfer and reaction tower system used for the scrubbing, stripping or chemical reaction between gases and liquids. The system comprises a top head having a suspension means, a bottom head, and a shell capable of retaining and supporting a suspended packing bundle. The shell is capable of securely and removably attaching to the top head and bottom head, thereby creating a single tower capable of being suspended by the suspension means in the top head. Various embodiments of the system can be adapted for the purposes of chemical vent scrubbing, absorption, odor abatement, gas-liquid chemical reactions, or similar processes. The tower can be operated in the classical counter current or concurrent flow modes, under pressure, or in a partial vacuum.
