How is a desulfurization tower designed?
Thread Content
Pressure-bearing equipment is generally designed, manufactured, and inspected in accordance with the standards GB150-1998 for steel pressure vessels. What type of equipment is a desulfurization tower? It is a pressure-free equipment; therefore, should it be designed and manufactured according to JB/T4735-97 for steel welded pressure-free vessels? Additionally, the standards only provide calculations regarding the strength of the equipment, and the wall thickness is determined solely based on strength requirements; yet the minimum thickness specified in these standards is rarely actually used. For pressure-free equipment, the wall thickness also plays a role in determining stiffness. How can one accurately calculate the wall thickness required to ensure sufficient stiffness? I would appreciate some guidance on this matter. Thank you.
Designed in accordance with JB/T4710
Atmospheric pressure towers should also take wind loads and seismic loads into consideration, not just meet strength requirements; in addition, the deflection requirements at the top of the tower must also be considered
You need to check whether it falls within the scope of application of the 4710 tower vessel standards; if it is within this range, then the design pressure for internal-pressure towers will be no less than 0.1 MPa, and thus there is no issue related to 4735. For containers that meet the requirements of 4710, strength is not the determining factor; rather, it is the bending stresses generated by wind loads and seismic loads that play a key role.
It shall be designed in accordance with JB/T4710-2005 \"Steel Tower Vessels\", and the calculations shall be carried out in accordance with GB150.

I believe it should be designed in accordance with the standards for steel tower-type vessels, but also verified according to the standards for steel atmospheric-pressure vessels, while meeting the design, manufacturing, and acceptance specifications for large steel vessels. Because most desulfurization towers do not meet the requirements of JB4710, they are still close to meeting those requirements. At this point, it is necessary to determine the shear strength of the equipment.

The pressure in the desulfurization tower is not high enough to meet the standards for pressure vessels; however, if it is cylindrical in shape, the stability can be calculated by referring to the specifications for towers. For wind load and seismic considerations, the specifications for towers or steel chimneys can be used as a reference
