A process () for the recovery of solvent () from solvent-containing cellulosic particles () is shown, the process comprising the steps: a) extracting the solvent () from the cellulosic particles () by means of a liquid extraction medium (), thereby obtaining a solvent-enriched extraction medium (), and b) obtaining the recovered solvent () from the solvent-enriched extraction medium (). In order to improve the efficiency of the process, it is proposed that in step a) the solvent () is extracted from the cellulosic particles () in a continuous flow extraction reactor (), wherein the extraction medium () continuously flows through the extraction reactor () to extract the solvent () from the cellulosic particles ().
