Open area ratio of atmospheric pressure column trays
Thread Content
I would like to ask the experts: what is the opening ratio of the trays in an atmospheric pressure tower as it moves upward from the feed section? And the reason?
Is it an atmospheric distillation column in oil refining? Atmospheric pressure columns have many sections, and the most important aspect is the segmentation of these sections. Generally, they can be divided into the top recirculation section, the normal line section, the first sub-section of the normal line, the second sub-section of the normal line, the third sub-section of the normal line, the third line section, the vaporization section, and the stripping section. The number of orifices in each section is determined based on the gas-liquid load in that section, with the aim of ensuring that no bottleneck trays appear in any section and that the maximum load requirements are met.
