Table 5 Summary of Feasibility Assessment for Sample Fryer Co. – Description of Control Odour Source Technically Feasible? Notes Measure Fryers, Stack Optimization Technically Feasible If the odour loading results in off-site effects on the Seasoning immediate surroundings, improved dispersion by optimizing the stack parameters can be effective. Combining multiple stacks to one optimized stack may improve dispersion. Thermal treatment will be evaluated should additional Fryers Thermal Treatment: Technically Feasible measures be needed to control fugitive odours from the Recirculate fryer exhaust gas to dryers. fryer burner Modifying the characteristics of the exhaust gas by adding recirculation back to a burner for incineration as part of the air make-up would reduce odour emissions. The particulate matter, oil mist, and grease present in the exhaust gas must be considered. Fryers Thermal Treatment: Technically Feasible Thermal treatment will be evaluated should additional measures be needed to control fugitive odours from the Boiler Incineration dryers. This may require additional energy input to heat lines; this may be offset if there is a heat recovery system. Fryers Oil Mist Eliminator / Demister / Technically Feasible Systems have been previously installed and result in the – Screen Separator removal of particulate matter, grease, and oil mist by mist previously implemented eliminators which result in mitigate of odours. Fryers Rotoclone Technically Feasible A mist eliminator is currently installed for removal of particulate matter, grease, and oil mist.
