Hello to all: I have read some contributions to this group about methanol recovery and the different options. I would like to try the recovery before separation of bio and glycerol using a condenser that would receive the methanol fumes after finishing the reaction. I have a processor were I get 75¼C-80¼C as it is pressurized to 0,7 bar. The problem is that I have also read that due to the reversibility of the reaction, if after finishing my reaction I remove the methanol by reducing the pressure and directing the vapours through a condenser, or even I apply vacuum after despressurizing to do it faster, I can get a reduction of the conversion transforming some biodiesel into oil again. My question is: has anyone in this group measured or experienced this fact? Is there a real decrease of the yield or conversion?
