A reactor tube for a tubular reactor and a retaining device associated with the reactor tube; the reactor tube comprising an elongate tube defining a bore for receiving in use a catalyst and having an outlet at one end of the bore for discharging the catalyst out of the bore; the retaining device being configured to be rotatable between a first position and a second position; wherein in the first position the retaining device at least partially obstructs the outlet for retaining the catalyst within the bore; and in the second position the outlet is unobstructed sufficiently for permitting discharge of the catalyst out of the outlet.

Rotatable retaining device for tubular reactors

The invention relates to an exhaust system for the treatment of an exhaust gas comprising ammonia in an amount of up to 250 ppm, the system comprising: an exhaust gas inlet; an ammonia storage material arranged to receive an exhaust gas from the exhaust gas inlet; an ammonia oxidation catalyst arranged downstream of a selected portion of the ammonia storage material; and a heating device for heating gas before it passes through the selected portion of the ammonia storage material to release ammonia stored therein for treatment on the ammonia oxidation catalyst, wherein the system is configured so that the selected portion of the ammonia storage material changes over time. The invention further relates to a livestock house comprising the exhaust system and a method of treating an ammonia-containing gas.

Exhaust gas treatment system

A method of installing catalyst carriers into a first selected reactor tube of a tubular reactor. The method comprising the steps of: i) providing an installation tool, the installation tool comprising: a) an installation frame; b) a movable ram mounted to the installation frame and configured for pushing one or more catalyst carriers into the first selected reactor tube; and c) one or more anchors for releasably attaching the installation frame to the tubular reactor; ii) attaching the installation tool to the tubular reactor by engaging the one or more anchors in one or more reactor tubes located alongside the first selected reactor tube so as to align the movable ram with the first selected reactor tube; and iii) actuating the movable ram to push the one or more catalyst carriers into the first selected reactor tube.
