| Abstract: | Crude wood vinegar from Sanli New Energy Co. Ltd. is condensed by membrane technology of separation containing ultrafiltration, nanofiltration and reverse osmosis. The result shows, the recovery of total organic matter of original liquid can reach more than 90% and recovery of acetic acid is more than 85% while treatment capacity is about 300L/h. at the same time,water content of wood vinegar can reduce 45% after treated with single membrance module. |
