Owing to the shortage of conventional crude oil resources, great attention is directed towards the production of bio-based bulk chemicals from renewable resources.2,3-Butanediol, known as 2,3-butylene glycol(2,3-BDO), is a precious chemical itself because of its various applications as a printing inks, perfumes, softening and moistening agents, pharmaceuticals, anti-freeze agent, and liquid fuels. In this study, 2,3-BDO from fermentation broth was purified by multi-effect-evaporation-assisted distillation. The recovery 2,3-butanediol from fermentation broth consumes high energy due to its low concentration in fermentation broth with high boiling point(180°C) and removing 90 wt% of water. Thus, a multi-effect evaporation(MEE) was considered and investigated in detail to improve the process efficiency. This research was supported by Priority Research Centers Program through the National Research Foundation of Korea (NRF) funded by the Ministry of Education(2014R1A6A1031189) and C1 Gas refinery program funded by the Ministry of Science, ICT & Future Planning(NRF-2016M3D3A1A019132622). |
