【Abstract】 A novel reboiler with mass transfer function under high vacuum ( RMV reboiler for short ), which was developed by authors, was used for vaporizing ethyl acetate from solution with thermo-sensitive and high boiling point component. Because of the unique characters of RMV reboiler, this technology shows advantages as following: First of all, it realized continous process and largely reduced heating time. Furthermore, the processing capacity enhanced from 2.5t/h to 16t/h though the heating area increased only 3 times as that of original, and the ethyl acetate recovery enhanced from 96% to 98%. At the same time, the steam consumption was lowered 33.3% for per unit input.更多还原
