Ammonium Nitrate Evaporator

Ammonium Nitrate Evaporator

Sable Chemicals - Zimbabwe

The Sable Chemicals Ammonium Nitrate Evaporator produces a high grade ammonium nitrate for prilling in the clients’ prilling facility. The 1st effect evaporator processes approximately 40000 kg/hr of 83% Ammonium Nitrate using a steam driven vacuum falling film evaporation stage.

The concentrated Ammonium Nitrate liquor is fed into the 2nd Effect Evaporator, which has an upper evaporator section and a lower mass transfer section within a single unit. The air used for the evaporation in the 2nd effect is supplied by a high pressure fan assembly. The vapour / air mixture leaving the 2nd stage evaporator is vented to atmosphere.  All the steam and process condensate from the plant is recovered and returned to the client as process water.
