The accumulation of corn dust and dried distillers grain (aka distillers dried grains) during ethanol production creates yearly maintenance issues for ethanol plants. The dust coats the walls, ceilings, tunnels and grain pits and impacts the performance of the thermal oxidizers, stack economizers, induced draft fans, and coils.
Dried Grains in Storage
Dry ice blasting efficiently removes the dust and dried distillers grain residue from electrical, thermal and facility equipment and restores operational efficiency and safety without generating a secondary waste stream. Our experience with dry ice blasting eases cleaning procedures during annual or bi-annual maintenance shutdowns. Ethanol plants can save thousands of dollars in energy costs with routine and proper cleaning.
In addition to dry ice blasting, Snow White Services offers hydroblasting, steam blasting, soda blasting, abrasive blasting, chemical cleaning, vacuum truck, transportation, and waste disposal services during planned and unplanned maintenance activities.
