Treating Variable VOC Loadings with Hot Gas Bypass
A soil and groundwater remediation firm had contacted Anguil Environmental Systems with a need to process increased VOC loading with their two Anguil Model 50 RTOs.
The customer was experiencing high variability in VOC loading during remediation and their RTOs would shut down due to excessive temperature in the combustion chambers.
Anguil modified both RTOs to incorporate a Hot Gas Bypass (HGBP), a feature designed to allow incoming process streams to have LEL levels up to 25%. HGBP diverts hot gases from the combustion chamber to the stack during high VOC loading conditions. The residence time of the diverted hot gases as they pass to the stack insures the emissions are destroyed without affecting the system’s destruction efficiency.
HGBP is commonly ordered on new RTOs with either highly consistent VOC loading or high variability in loading. HGBP is also commonly ordered from Anguil for retrofitting on to Anguil built RTOs and oxidizers supplied by other manufacturers.
