Interpretive Summary: Particulate emissions result from cotton ginning where large amounts of air are used to convey seed cotton, seed, lint, and trash. Agricultural operations, including cotton gins, are most often required by the States to use reasonably available control technology or best available control technology to control emissions of particulate matter. The most common type of emissions control device used at cotton ginning plants is the cyclone. Cyclones are efficient, reliable, low-cost, and require little maintenance. When properly sized, constructed, and maintained, cyclones can reduce a gin’s emissions such that the state PM regulations can generally be met. This report is intended to be a tool for gin plant managers and operators aid in determining how to properly size, construct, operate, and maintain cyclones.
Technical Abstract: Cyclones are the most common type of emissions control device used in agricultural processing operations. Cyclones are efficient, reliable, low-cost, and require little maintenance. When used properly, cyclones effectively separate particulate matter from air streams, allowing compliance with state and federal air pollution regulations. Guidelines and techniques intended to help gin plant managers and operators determine if existing cyclones are correctly sized, properly constructed, and adequately maintained are reviewed. Methods presented are such that measurements can be made with minimal equipment and operating parameters determined with simple or no calculations.
