METHANOL DISTILLATION TECHNOLOGY


Methanol distillation technology Johnson Matthey

 

Dependent on the grade of methanol required, there are different options for methanol distillation. To produce DME or MTO-grade methanol, only a single column is required to remove the dissolved gases and some of the light by-products. To produce refined methanol for chemical or fuel usage, for example Federal AA and IMPCA grade methanol, a two or three column refining system is used. The three column system uses the least heat so is preferred where energy costs are high or the heat for distillation is not readily available.

  • Single column for fuel and methanol to olefins ( MTO) grade
  • 2 column for refined methanol meeting AA and IMPCA specifications
  • 3 column for refined methanol meeting AA and IMPCA specifications
