PROBLEM TO BE SOLVED: To distillate efficiently a charge liquid supplied to a distillation column by being allowed to flow down uniformly in a distillation column by a method wherein the charge liquid is charged by being sprayed in a tray or a packed distillation column. SOLUTION: Though a distillation apparatus prevents liquid from being ununiformed by spraying a charge liquid such as a raw material liquid and/or a reflex liquid, spraying is executed so as to wet uniformly the whole face of a tray 12 or a packing with liquid drops by setting appropriately a type of a spray, the number of nozzles, and a position of the nozzle when the charge liquid is supplied to a distillation tower 10. When the reflux liquid, for example, is supplied to a crest of the tower, the liquid is sprayed so as to be dispersed uniformly on a tray 12 from a distributer 14 having a spraying charge means. Then, even when a diameter of the distillation column 10 is large, the charge liquid can be uniformly dispersed. Even in the case where a viscosity of the charge liquid is high and a surface tension is large, a gas liquid contact efficiency is high, or even in the case where the charge liquid can be easily separated into biliquid phases such as an oil phase and an aqueous phase, the charge liquid can be uniformly dispersed.
