METHOD AND APPARATUS FOR SEPARATING SOLIDS FROM PYROLYSIS LIQUID

摘要

The invention relates to a method for separating solid matter from a pyrolysis liquid produced from solid raw material via flash pyrolysis by condensing the pyrolysis steam obtained into a pyrolysis liquid. According to the invention, most of the solid matter contained in the pyrolysis liquid obtained from the pyrolysis process is separated from it in a separating device after a suitable delay, by separating from the surface of the pyrolysis liquid a desired surface fraction having a high solid matter content. The apparatus of the invention comprises at least one separating device (3) for the separation of solid matter and at least one control device (9) for setting a suitable delay and/or controlling the separation of a desired surface fraction, and the apparatus is disposed substantially in conjunction with a flash pyrolysis apparatus (1, 2).
