The working principle of Propane-Propylene (PP) Splitter is based on the separation technology in physical chemistry.

First, the material mixed with propane and propylene enters the distillation tower. There are different temperature gradients in the distillation tower, with higher temperatures at the bottom of the tower and relatively lower temperatures at the top of the tower.

Due to the difference in the boiling points of propane and propylene, when the mixture is heated, the propylene with a lower boiling point is more likely to vaporize into gas and move upward. The propane with a higher boiling point tends to remain in liquid form and flow downward under the action of gravity.

In the distillation tower, a series of plates or fillers are used to increase the gas-liquid contact area and contact time. During the ascent, the gas will continuously exchange heat and substances with the descending liquid, further promoting the separation.

As the gas rises to the top of the tower, the propylene in it is cooled and liquefied by the condenser to obtain a propylene product with higher purity. At the bottom of the tower, liquid mainly composed of propane is collected.

The whole process is a dynamic equilibrium process, and the separation effect is optimized by precisely controlling parameters such as temperature and pressure. At the same time, the design of the distillation tower is also crucial. Reasonable tower plate structure and filler type can improve separation efficiency and production capacity.

In order to ensure the stable operation and good separation effect of the Propane-Propylene (PP) Splitter, it is also necessary to strictly control the feed rate, temperature, etc. of the material. In addition, regular maintenance and overhaul are also essential to ensure the performance and safety of the equipment.
