| 摘要 |
The present invention relates to a method for controlling the water content in a pyrolysis liquid comprising: a) producing a pyrolysis vapour comprising condensable compounds and non-condensable gases at a temperature equal to, or below 70° C and at a pressure equal to or below 1.5 bar; b) introducing the vapour phase in a condenser, condensing the condensable compounds of the pyrolysis vapour to obtain a condensate at a temperature equal to, or below, 70° C and at a pressure equal to or below 1.5 bar, and separating the non-condensable gases from the condensate; c) introducing at least part of the condensate into concentrator and concentrating said condensate by removing a certain amount of water at a temperature equal 1 to, or below 80° C thereby obtaining a concentrate; d)introducing the concentrate obtained after step c) into condenser and mixing it with the condensate present in condenser thereby obtaining a pyrolysis liquid with controlled water content. |
