Abstract
In impregnating or extracting treatments of resin-containing wood substrates using a resin-soluble supercritical fluid as delivering or extractive solvent medium problems due to exudation of resin from the wood substrate at pressure release necessary before the termination of the treatment are avoided or reduced by a controlled pulsating pressure release down to atmospheric pressure. Thereby the total process time can be substantially reduced.
