Delignification through the Mini-O process presents itself
as much more inexpensive alternative when compared with the
conventional delignification with Oxygen. This is due to the
fact that the Mini-O process needs substantially smaller investment
in new equipment such as: MC pump, mixer and reactor or retention
tube.

Mini-O operational conditions are less intense then the conventional
Oxygen delignification, therefore its benefits are similar
to the ones seen in the conventional process, although with
proportionally lower values. The Mini-O process offers many
interesting benefits to plants with no capital for high investments
