Comprehensive particulate sampling of all emission points from a newly constructed cotton gin was undertaken to measure the extent of emissions from each phase of operation of the gin. The purpose was to quantify emissions from air pollution control equipment specified in proposed and subsequently adopted cotton gin regulations of the Tennessee Division of Air Pollution Control. Two Rader high volume samplers were utilized to measure particulate matter from both high and low pressure exhausts. High pressure exhausts were released through cyclones with a 2D-2D configuration. Low pressure exhausts originated from first and second stage lint cleaners with 16D perforated condenser drums containing .045 inch diameter holes, and third stage Moss lint cleaners and battery condenser wrapped with 80 mesh screen. Emissions were compared in several respects and the overall emission rate for the gin was .68 pounds of particulate per bale of cotton. Corresponding visible emissions by certified smoke readers indicated a significantly higher opacity from lint cleaners and the battery condenser than from the cyclones.
