In other examples, the link may be a propped tie. Alternatively or additionally, a support perch may be provided for supporting a ring base of an adjoining module.

A static mixer for liquids or gases includes a housing having a continuous inner surface defining a fluid flow path for liquids or gases, an inlet to the fluid flow path, and an outlet from the fluid flow path, and an insert extending longitudinally through the fluid flow path between the inlet and the outlet. The insert is elastically expansive to exert outwardly directed pressure against the continuous inner surface of the housing. In one embodiment, the insert is hollow and has deflectors dispersed therethroughout and each projecting inwardly into the fluid flow path. In another embodiment, the insert includes a helical deflector extending inwardly into the fluid flow path from the continuous inner surface, and helically about a longitudinal axis of the housing.

One aspect of the invention relates to a method comprising a single stage conversion of an atmospheric pollutant, such as NO, NO.sub.2 and/or SO.sub.x in a first stream to one or more mineral acids and/or salts thereof by reacting with nonionic gas phase chlorine dioxide (ClO.sub.2.sup.0 , wherein the reaction is carried out in the gas phase. Another aspect of the invention relates to a method comprising first adjusting the atmospheric pollutant concentrations in a first stream to a molar ratio of about 1:1, and then reacting with an aqueous metal hydroxide solution (MOH). Another aspect of the invention relates to an apparatus that can be used to carry out the methods disclosed herein. The methods disclosed herein are unexpectedly efficient and cost effective, and can be applied to a stream comprising high concentration and large volume of atmospheric pollutants.

A mixer assembly unit, especially for an exhaust system of an internal combustion engine of a vehicle, includes a mixer body (48) with an incoming flow side (58) and with an outgoing flow side (60); and a carrier element (24) with a carrier element body (44) enclosing the mixer body (48) radially on an outside in relation to a mixer longitudinal axis. The mixer body (48) includes a plurality of flow deflection elements (62) and at least one holding area (70). The carrier element (24) includes a counter holding area (46) in association with a holding area (70). The counter holding area (46) is connected in substance to the holding area (70). The counter holding area (46) overlaps the holding area (70) at least partly radially on a side oriented in a direction of the outgoing flow side (60) of the mixer body (48).

A gypsum slurry mixer output canister is provided, including a canister housing having an upper end, an opposite lower end and defining a canister interior, a cover secured to the upper end, a slurry inlet in operational relationship to the upper end, a spiral block associated with the upper end, and having a helical flow surface depending into the interior. A flow distributor is secured to the lower end and is in fluid communication with the interior, and a slurry outlet is defined by the lower canister housing end.
