Working principle of fractional distillation column 

fractional distillation column working，Steam rises inside the tower and gradually decreases in temperature. Components with different boiling points condense and collect at corresponding heights.
Multiple layers of trays or fillers (such as glass beads and metal mesh) are installed inside the tower to increase the gas-liquid contact area and improve separation efficiency.
High boiling point substances (such as heavy oil and asphalt) remain at the bottom of the tower; Low boiling point substances (such as petroleum gas and gasoline) accumulate at the top of the tower.
fractional distillation column of Reflux control: Control heat distribution through external reflux liquid and pumperround to ensure more stable operation
