1. A process for recovering a solvent from solvent-containing cellulosic particles, wherein the solvent is a direct dissolution solvent, comprising the steps:
a) initially extracting the solvent from the solvent-containing cellulosic particles by means of a liquid extraction medium consisting essentially of water, thereby obtaining a solvent-enriched extraction medium, and
b) obtaining a recovered solvent from the solvent-enriched extraction medium,
wherein in step a) the solvent is extracted from the solvent-containing cellulosic particles in a continuous flow extraction reactor, wherein the liquid extraction medium continuously flows through the continuous flow extraction reactor to extract the solvent from the solvent-containing cellulosic particles.
