How to optimize the structure of the equipment support in the cold box of an air separation plant?

With the large-scale development trend of air separation equipment, the tower bracket of the equipment in the cold box supporting it also tends to be large-scale. The traditional bracket structure often has the problems of complex structure and limited bearing capacity, which limits the performance and safety of air separation equipment to a certain extent.
Deere Air Separation uses finite element analysis software to optimize the model of the tower bracket, which is commonly used in air separation equipment, to achieve the purpose of improving the bracket's bearing capacity, reducing processing difficulty and saving material costs.
The finite element analysis software is used to model and analyze the traditional bracket structure, and simulate the force on the bracket in actual operation by correctly applying loads and boundary conditions. Considering the low height of the tower bracket and the fact that there is no need to consider the effects of wind load, seismic load and ice and snow load, the main loads are the self-weight of the bracket and the weight of the tower and its accessories. The design is optimized for the traditional bracket structure, such as ring plate, fascia plate, vertical pipe and connecting straight pipe components. A straight pipe between the connecting risers is replaced by two inclined pipes, which support the ring plate obliquely upwards so that the angle between it and the two risers becomes smaller, thus improving the stability of the support.
This optimized support structure of Deere Air Separation has excellent performance in practical application and provides a strong guarantee for the stable operation of the air separation equipment.

Special pressure-bearing equipment generally bears internal pressure, that will cause tensile stress inside the shell, which is called working stress. The working stress is directly proportional to the pressure and diameter, and inversely proportional to the vessel wall thickness. The axial stress is half of the circumferential stress. Therefore, for cylindrical vessels, the stress of longitudinal weld is twice that of girth weld. Because the geometric shape of the spherical shell is symmetrical to the spherical center, and the axial stress is equal to the circumferential stress in numerical value. Therefore, the wall thickness of the spherical vessel can be reduced by half as much as that of the cylindrical vessel under the same pressure and diameter.
