Abstract

The invention provides a process for continuous extraction of lignocellulosic material, the process comprising at least one stage comprising the steps of a) conveying the lignocellulosic material into an extractor, b) forming, in the extractor, a suspension of the lignocellulosic material and a solvent, c) extracting the lignocellulosic material in the extractor with the solvent, d) withdrawing part of the suspension from the extractor and conveying it to a pressing device at a flow rate m4, e) separating the solvent from the lignocellulosic material by pressing off the solvent from the lignocellulosic material in the pressing device and conveying pressed-off solvent as a pressate to a pressate tank at a flow rate rh7, f) withdrawing pressed lignocellulosic material from the pressing device at a flow rate rh6, g) returning a first part of the pressate from the pressate tank at a flow rate rh8 into the extractor, h) withdrawing a second part of the pressate as an extract from the pressate tank at a flow rate rh9, i) Adding solvent to the lignocellulosic material in any one or more of steps a, b, c, d, e or g at a flow rate m2.
