A new air dehydration process for wood dryers - part II. Elimination of organic compounds

In this second part of the study, the ability of the dehydration unit to fi x the organic compounds by wood is evaluated in the particular case of gree n fir drying at 70 degrees C. The organic compounds are condensed in a bubb ling device and analysed with a flame ionisation detector. From these analy sis are deduced the mass fraction of organic compounds in the gas phase, th e mass flow rate of these compounds released by wood and the one absorbed b y TEG. These last results permit to define an equivalent efficiency of the absorber to capture organic compounds present in the drying air.
