Abstract: The invention relates to an installation for the thermal drying of wood by CO2 sequestration, having at least one CO2 atmosphere drying module comprising: a drying chamber (1), means of supply of CO2 (3), means of heating (2), means of gas circulation (4), means of recycling (600) of the CO2, metrological means (5), means of supply of CO2 (3), and a computerised control system (6), characterised in that the means of gas circulation (4) comprise a flow reversal module configured to allow the circulation of CO2 in a first direction forming a closed-loop circulation duct for the CO2 gas mixture, and in a second direction of circulation opposite to the first direction, capable of rendering uniform the thermal distribution in said drying chamber (1).

Abstract: The invention relates to an implemented method for thermally drying wood comprising the following stages: Acquiring the metrological data and parameters of the wood to be dried (S1); saturating (S2) the drying chamber (1) with CO2 Adjusting the humidity of the wood (S3) by heating reheating (S4) the CO2 circulating in the drying chamber (1) in a first phase, and subsequently reheating the CO2 circulant in the drying chamber (1) in a second phase until the measured humidity of the wood reaches a chosen intermediate target value Hi, Reducing (S5) the temperature of the heating chamber (1) down to a chosen third stabilisation setpoint temperature T3, Reducing the temperature of the heating chamber (1) in a second phase (S6) And the dried wood obtained directly using the method according to the invention.

Abstract: The invention relates to a process for the thermal drying of wood using a drying plant comprising: a drying chamber (1); means for supplying CO2 (3) at a selected pressure and temperature; circulation means (307, 203) for forcing the circulation of the gaseous fluid; heating means (2) for heating the gaseous heat transfer fluid; extraction means (4) for extracting the air inside the drying chamber 1; metrology means (5) for measuring variations in the physical measurements of the drying plant during heating; and operating means (6) for controlling the means used according to programs, adapted to the quality of the dried wood sought, and processing means for readjusting the operating parameters.
