Traditionally, ethanol from corn has primarily been produced through dry- and wet-milling processes. The majority of U.S. ethanol production is from dry-grind technology. The traditional dry-grind process grinds the whole corn kernel and mixes it with water and enzymes. The mash is then cooked to liquefy the starch further.
In addition to the requirement by NFPA 85 for inerting a tripped mill system, coal mill OEMs usually recommend that a mill system be inerted during both the normal mill start-up and shut down process. Steam is commonly employed in the power industry for coal pulverizer system inerting, due to its ready availability and cost effectiveness.
