Abstract
A rotary valve thermal oxidizer including an interfacial seal disposed between rotating and fixed valve portions to prevent the mixing of treated and untreated gas streams. In a preferred embodiment, the valve sealing device includes a flowable sealing material contained within a receptacle, and contacted by a partition nested within the receptacle. Other sealing devices, as well as purge and/or sealing gases, may be employed to prevent leakage, while avoiding the use of machined parts.
