Supercritical fractionating apparatus and process

Abstract

The present invention provides a super fractionating apparatus and process, consisting of a fractionation column having an adsorbent body that assists in the fractionation process, and further includes a carbon dioxide supply unit, a carbon dioxide flow pipe, a raw material supply unit and a raw material flow pipe. The carbon dioxide flow pipe connects to the carbon dioxide supply unit and the fractionating column, and a pressure unit and a temperature control unit are configured on the carbon dioxide flow pipe. The raw material flow pipe connects to the raw material supply unit and the fractionating column, and a pressure unit is configured on the raw material flow pipe. The fractionating column having the adsorbent body disposed therein causes turbulence in the fluid within the fractionating column, thereby increasing fractionation efficiency and assisting in stabilizing the extracts, which facilitates collection thereof.
