fractional distillation column of crude oil

A fractional distillation column of crude oil is a key equipment used in industry for petroleum fractionation, which heats crude oil to raise its vapor and separates it based on the boiling point differences of different components.
fractional distillation column of crude oil of During the distillation process, crude oil is heated to a certain temperature, and steam enters from the bottom of the distillation tower. As it passes through the multi-layer plate and collection tray, components with different boiling points are sequentially condensed and collected. The lighter components condense at the top of the tower, the heavier components condense at the bottom of the tower, and the residue at the bottom of the tower is called residual oil or oil.
In addition, fractional distillation column of crude oil of the design of the fractionation tower also utilizes a reflux device to send the condensate from the upper layer back to the lower plate, in order to improve the fractionation efficiency. The control strategy of the fractionation column can also affect the energy efficiency of the fractionation process, such as preheating the feed stream by controlling the pumping flow and external reflux, thereby improving energy efficiency
