Dangers of methanol

  1. Oct 22, 2015 #1
    For a vessel containing liquid methanol (95%) and other substances (methanol takes up about 40 wt%), which operates at 4.5 bar and 75C, what would happen if the vessel ruptures? SInce it's at a relatively high pressure, the methanol should still remain as liquid and hence no explosion? What kind of dangers would the chemical exposure pose?

    Pressure drops when the vessel ruptures. At atmospheric pressure, it is above the boiling point, so I would expect bad results if pressure drop is rapid...
    To make it worse, methanol will replace oxygen and is easily flammable. It is also toxic, even in relatively small quantities.

    When I worked with heated methanol at a pilot plant, it was in a separate building equipped with fire suppression and blow-out (rupture) panels. It is serious business.
