Background

The existing rectification is usually carried out in a rectifying tower, and gas and liquid phases are contacted in a countercurrent way to carry out interphase heat and mass transfer. The volatile component in the liquid phase enters the gas phase, and the non-volatile component in the gas phase is transferred into the liquid phase, so that the nearly pure volatile component can be obtained at the top of the tower, and the nearly pure non-volatile component can be obtained at the bottom of the tower. The feed liquid is added from the middle part of the tower, and the tower section above the feed inlet further thickens the volatile component in the rising steam, which is called as a rectifying section; the section of the column below the feed opening, which extracts the volatile components from the descending liquid, is referred to as the stripping section. Condensing the vapor led out from the tower top, returning a part of condensate as reflux liquid from the tower top to the rectifying tower, and obtaining the rest distillate as a tower top product. The liquid extracted from the tower bottom is partially gasified by a reboiler, the vapor rises along the tower, and the rest liquid is used as a tower bottom product. The ratio of the amount of liquid refluxed into the column at the top of the column to the amount of product at the top of the column is called the reflux ratio, and the size of the reflux ratio affects the separation effect and the energy consumption of the rectification operation.
