Abstract:
      Various odor is produced due to n-hexane, oil and soybean meal in the solvent extraction of soybean, which need to be treated to meet the standard emission. Taking two 2 500 t/d soybean flake leaching production lines as example, the process flow and main equipment of the alkali washing + UV photolysis process for treating odorous exhaust gas were introduced. The practice showed that the deodorization efficiency reached more than 98% with the alkali washing + UV photolysis process, and the treated exhaust gas met the emission requirements of GB 14554—1993 and DB 12/524—2014.
