Abstract
The present invention relates generally to radial flow vessels and processes to achieve even fluid flow distribution through the bed during purification, separation or reaction processes. The radial bed vessel is designed such that the ratio of the cross-sectional flow areas of the flow channels is in proportion to the ratio of the mass flow rates of the process gas with the proportionality constant between 0.7 and 1.4. In addition, the channels each have a cross-sectional flow areas such that the pressure change within each channel is less than or equal to 10% of the pressure drop across the bed of active material under the process operating conditions for the particular gas employed.
