BDF 製造における気泡式脱メタノール装置の開発

抄録

Biodiesel fuel (BDF) is expected as a biomass fuel in future which can solves global warming and petroleum resource conservation problem. We proposed the dry process which has no need of washing water and no waste water treatment compared with the conventional wet process. In the unit, gas was supplied by a gas pump through a gas bubbler into crude BDF, then the exist gas contained methanol (MeOH) vapor passed through a condenser and the MeOH was collected in vessel. It was a closed system that MeOH-free gas from the condenser returned in the inlet of the gas pump. A large scale of bubble stripping unit has been developed in this study, and it is effective to remove residual MeOH from crude BDF. We have set the value for the standard of performance evaluation and calculated of power consumpution.
