Abstract: An opposed axial flow reaction vessel includes a process fluid collection system within the body of the vessel in fluid communication with one or more of the ports; a bed of particulate catalyst or sorbent containing a layer of inert particulate material around the process fluid collection system; and the one or more of the ports are configured such that a process fluid fed to the vessel is passed axially and in the opposite direction through the fixed bed of catalyst or sorbent and is collected by the process fluid collection system disposed centrally within the bed and in fluid communication with one or more of the ports.

Abstract: A method of adapting an axial flow reaction vessel having opposed ports to an opposed axial flow reaction vessel includes installing a process fluid collection system within the body of the vessel in fluid communication with one or more of the ports; providing the vessel with a bed of particulate catalyst or sorbent containing a layer of inert particulate material around the process fluid collection system; and adapting the feed to the vessel through one or more of the ports such that a process fluid fed to the vessel is passed axially and in the opposite direction through the fixed bed of catalyst or sorbent and is collected by the process fluid collection system disposed centrally within the bed and in fluid communication with one or more of the ports.

Abstract: A method of adapting an axial flow reaction vessel having opposed ports to an opposed axial flow reaction vessel includes installing a process fluid collection system centrally within the body of the vessel in fluid communication with one or more outlet ports of the ports; wherein said process fluid collection system includes a perforate member defining a chamber and a conduit in fluid communication with the chamber, the conduit being adapted for attachment to the one or more outlet ports, providing the vessel with a bed of particulate catalyst or sorbent around said process fluid collection system; and adapting a feed to the vessel through one or more inlet ports of the ports such that a process fluid fed to the vessel is passed axially and in an opposite direction through the fixed bed of catalyst or sorbent and is collected by the process fluid collection system.
