Appendix B Control Equipment Descriptions – Appendix B provides general information on the control measures identified in this example OCR. Details such as whether the control measure is considered to be in the developmental stage, where it may be applicable, and what limitations may exist, are given. Facilities may also consider contacting equipment suppliers for further information to determine whether a particular control measure may be technically feasible at their site. This information is provided in order to illustrate what may be considered when assessing the feasibility of a control measure. Including this level of detail on potentially feasible control measures is not a requirement of the OCR and is provided as reference material only. B.1 Oil Mist Eliminator B1.1 Technologies Demister / Screen Separator B1.2 Emission Characteristics Exhaust gas with oil mists or liquid droplets. B1.3 Air Emission Sources Common Applications: Oil Fryers Brine Desalination Petroleum Refining Cooling towers B1.4 Description A demister or mist eliminator is a device that enhances the removal of liquid droplets in a vapor stream. Demisters may be mesh type, vane demisters, swirl mist eliminators, Brownian diffusers, or other structure. Due to the influence of the demister, the mists aggregate into droplets that are heavy enough to separate from the vapor stream. B1.5 Applicability and Performance Direct impact demisters have high removal efficiencies of up to 100% over 5 micron. Demisters are simple structures with low capital and maintenance costs. B1.6 Limitations Routine maintenance required to prevent demister pad clogging or flooding, increasing the pressure drop.
