Reason for using top feeding for butadiene storage tank feeding

Answer: Butadiene is a material with self-polymerization properties; if fed from the top of the tank, it may cause oxygen to dissolve in the material, thereby triggering a self-polymerization reaction. Therefore, using an upward feeding method can effectively avoid this problem. Furthermore, feeding from the bottom of the tank can prevent self-agglomeration by stirring the material inside the tank, and it can also promote mixing and uniform distribution of the material. Therefore, the reason for using an upward feed method for the butadiene storage tank is mainly to prevent self-polymerization and to ensure uniform distribution and mixing of the material. .

Either there’s a problem with the logic, or there’s an issue with the way it’s expressed

It is necessary to clarify whether top feeding of butadiene means direct feeding from the top, or feeding by interpolation from the top! Direct feeding from the top deviates from the petrochemical industry standards; therefore, it is necessary to consider ways to eliminate the risk of static electricity generated by such top feeding ； The advantage is that it can effectively lower the gas phase temperature, providing good effectiveness in preventing the gas-phase polymerization of butadiene. Our company’s circulating cooling pipelines are set up in this manner. Top-interpolated feeding is employed to meet the requirements of petrochemical standards, which goes without saying; however, the downside is that the gas phase temperature in the storage tank cannot be controlled, which can lead to the formation of butadiene gas-phase polymers and subsequent blockages in the pipelines.

Let me check the drawings; it should be the first type. Thank you for the advice
