PROBLEM TO BE SOLVED: To provide a precision distillation refining apparatus and method which heats a distillation object substance to be precisely distilled and refined properly in a short time in the whole process of distillation, can accurately control the heating temperature, thereby, can refine a high-purity distilled product with a preferable yield and is excellent also in energy efficiency.SOLUTION: In a precision distillation refining apparatus having a distillation tower including a boiler part into which raw material to be distilled and refined is charged, a gas-liquid contact part and a condenser part, a plurality of receivers into which respective products as fractions after distillation refining flow through a process line from the distillation tower and a vacuum pump for turning the receivers and the condenser part of the distillation tower into a decompressed state or a vacuum state through a vacuum line as main constituent elements, electromagnetic inductive heating means for performing temperature control respectively independently for the distillation tower, the process line, the receivers and the vacuum line which constitute the distillation refining apparatus is provided such that respective zones can be controlled in optimum temperature conditions in accordance with a kind of the raw material or the product in the whole processes of distillation refining to perform the distillation refining.SELECTED DRAWING: Figure 1 |
