Towers, Columns
Process towers(columns) are vertical (usually tall) apparatus in which distillation prcess takes place in refineries and (petro)chemical plants. They are designed to withstand combination of weight, wind, seismic loads in addition to internal (or external) pressure and temperature. Besides the comprehensive design, tight tolerances in fabrication is requires to allow for internals installation and assembly and integrity of column in upright condition.
