The Application of Dalian Spherical Storage Tanks in the Petrochemical Industry

In the field of petrochemicals, Dalian spherical storage tanks play an indispensable and critical role.

From the perspective of raw material storage, spherical storage tanks provide safe and efficient storage space for a large amount of liquid and gaseous petrochemical raw materials. For example, crude oil is often stored in spherical storage tanks before entering the refining process. Its unique spherical structure, compared to traditional vertical or horizontal storage tanks, is subjected to more uniform forces and can withstand higher pressures, which is important for storing volatile, flammable, and explosive crude oil. At the same time, the footprint of spherical storage tanks is relatively small, which can achieve intensive utilization in chemical parks with scarce land resources.

Spherical storage tanks also perform well in the storage of intermediate and finished products. Chemical products such as liquefied petroleum gas (LPG), propylene, ethylene, etc. have strict storage conditions, requiring not only pressure resistance but also strict temperature control. Spherical storage tanks, with their excellent insulation performance, effectively reduce heat transfer, ensuring that these products are in a stable liquid or gas state, preventing adverse chemical reactions such as gasification and polymerization caused by temperature changes, and ensuring product quality.

Moreover, with the advancement of technology, the intelligent monitoring and operation system for spherical storage tanks is becoming increasingly sophisticated. By installing various sensors, real-time monitoring of parameters such as pressure, temperature, and liquid level inside the storage tank can be carried out. Once an abnormality occurs, an alarm can be quickly issued and the control system can be linked to take corresponding measures, such as automatic pressure adjustment and emergency cutting off of feed, greatly improving the safety of production and operation.

In short, Dalian spherical storage tanks, with their unique advantages, have steadily established a solid foundation for the stable and efficient development of the petrochemical industry, from raw materials to finished products, and continue to promote the petrochemical industry to new heights.
