Method and installation for separating wood constituents from gases produced during wood processing

摘要

The invention relates to a method and an installation for separating wood constituents from gases produced during wood processing. According to the inventive method, the treatment comprises three stages. Stage one takes place in a contact apparatus for the mixing of and material exchange between the gas phase and the liquid phase (1). During stage two, the gas is cooled with simultaneous condensation of the gas constituents. In stage three, the terpenes are separated from the liquid phase (2).
