摘要：
The invention relates to a method for processing an aqueous gel of nanofibrillar cellulose by removing water from the aqueous gel by means of an organic solvent miscible with water. In the method: aqueous gel is introduced into a volume of organic solvent miscible with water in a controlled manner so that the aqueous gel is kept as a separate phase and forms discrete physical entities containing the nanofibrillar cellulose within the phase; water is changed with the organic solvent in said discrete physical entities of nanofibrillar cellulose; and the physical entities are separated from the volume of organic solvent.
