It is mainly because the vapor-liquid load in the upper part of the vacuum tower is relatively low. Correct +2 In-depth discussion +5 @ Guan Gongyu
Due to the reduction in its gas-liquid phase load.
At the upper part of the vacuum tower, since the gas and liquid phase loads are relatively low, the corresponding tower diameter is also smaller.
The vapor-liquid load in the upper part of the vacuum tower is relatively low.
The gas-phase load at the top of the tower is relatively low
In the upper part of the vacuum tower, since the loads on the vapor and liquid phases are relatively low, the corresponding tower diameter is also smaller
At the upper part of the vacuum tower, since the loads on the vapor and liquid phases are relatively low, the corresponding tower diameter is also smaller.

Furthermore, due to the high temperature at the bottom of the pressure reduction tower, the residence time of the product at that level is too long, which facilitates chemical reactions such as cracking and condensation. This affects the quality of the product and is not conducive to long-term safe operation. To reduce the residence time of the product at the bottom of the tower, a smaller diameter is used for the stripping section of the tower as well. The middle section of the vacuum tower has a high vapor pressure load, so a larger diameter was selected accordingly.】
Why is the upper diameter of the vacuum tower smaller? A decrease in the upper vapor volume causes the tower diameter to shrink.
At the upper part of the vacuum tower, since the loads on the vapor and liquid phases are relatively low, the corresponding tower diameter is also smaller.
In the upper part of the vacuum tower, since both the gas and liquid phase loads are relatively low, the corresponding tower diameter is also smaller
