How to calculate this tower?
Thread Content
For a column-type vessel, the upper part serves as the heat exchanger section while the lower part is the cylinder section; these two parts are connected using flanges. I would like to know how this is taken into account when using SW for calculations. Should the flanges be considered within the SW heat exchanger calculation or within the SW vessel calculation? If they are included in the heat exchanger calculation, how are the additional bending moments and axial tensile forces related to the flanges entered? Is the additional bending moment equivalent to the maximum bending moment calculated for the vessel? Should the calculations for the heat exchanger section be carried out using the SW tower section calculations, or the SW heat exchanger section calculations, or should they meet the requirements of both sections?
It’s been a long time; same question, seeking help :)
