摘要

The present application relates to a purifying device and a purifying method. According to the present application, energy can be saved by a heat exchange between a raw material flowing into an alkanol purifying tower and a discharged material from the purifying tower. The alkanol purifying device includes the alkanol purifying tower and a pipe system. The pipe system includes an introduction root for introducing a raw material including alkanol to the purifying tower; and a discharge root discharging a flow including alkanol purified inside the purifying tower. The discharging root is formed to enable a heat exchange between the discharged flow including the purifying alkanol and the raw material flowing into.
