Mechanical calculation of the column apparatus. Three-section stripping distillation column

The object of the study is a column apparatus.

As a result of the study, the selection of structural materials and contact devices was made, the strength of the column apparatus body was calculated, the reinforcement of the holes, flange connections, the hatch cover, the wind load on the column apparatus, the reduced loads and the choice of support were made, and the strength of the column apparatus was checked.
