A polymer handling method for a polycrystalline silicon manufacturing device, wherein the polymer byproducts are treated in a manner that the silicon polymers are hydrolyzed. The method creates a heated treatment gas with a moisture content that both treats the polymer to a depth of about 0.25 mm to prohibit formation of the friction and shock sensitive layer near the polymer surface and keeps the hydrolyzed polymer humidified. Furthermore the polymer handling method includes inactivation of the polymer, removal of the polymer of the system and disposal of the polymer after removal.

Systems and methods are provided for improving the flow distribution in the high temperature zone of a cyclic flow reactor, such as a reverse flow reactor. The systems can include a plurality of mixing plates that can facilitate mixing of flows that have been maintained separately until a mixing location. Based in part on the use of a plurality of mixing plates, methods are provided for operating a reverse flow reactor with a temperature profile that has improved uniformity across the cross-section of the reactor. In some aspects, a flame diffuser can be included downstream from the plurality of mixing plates to further improve the uniformity of the temperature distribution.

A carbon monoxide oxidation device for oxidizing carbon monoxide contained in a hydrogen rich reformat gas includes a gas stream perturbation device designed as at least one propeller-shaped plate with a plate portion having a surface facing the gas stream and at least one blade which is connected to the plate portion and has a leading edge and an effluent edge, wherein a surface defined between leading edge and effluent edge is inclined in relation to the surface of the plate portion with a predetermined blade inclination angle, thereby defining at least one opening in the plate.

An exhaust system for a work vehicle includes a selective catalytic reduction (SCR) assembly that includes an SCR module. The SCR module includes a first exhaust flow path and a second exhaust flow path. The SCR assembly also includes an inlet configured to receive a flow of an exhaust solution, to direct a first portion of the exhaust solution to the first exhaust flow path, and to direct a second portion of the exhaust solution to the second exhaust flow path. The SCR assembly further includes an outlet mixer configured to receive the first and second portions of the exhaust solution and to direct the first and second portion of the exhaust solution out of the SCR assembly. The outlet mixer includes one or more features configured to mix the first and second portions of the exhaust solution.

A gas delivery system and method for delivering reactants such as a first gas through a first conduit and a second gas through at least one second conduit, for example, through a plurality of second conduits. The plurality of second conduits may each have a length, wherein at least a portion of the length is entirely disposed within the first conduit. In an implementation, the first conduit may deliver carbon monoxide and the one or more second conduits may deliver carbon monoxide doped with a catalyst such as iron pentacarbonyl. The first and second gases may be introduced into a reaction vessel such as a reactor chamber and used to form carbon nanotubes.
