Column & Booms allow the use of fully automated production techniques, which increases quality and reduces production time & operator fatigue. Column & booms enable to achieve downhand longitudinal welding and vertical welding.

Column internals are the vital parts of packed column, which together with packing and column body constitutes a whole packed column. The role of all internal is to improve the contact of liquid and gas, through it packed column can be more efficient and have larger capacity, so the internals design will affect the packing the whole column's performance. In addition, besides the inherent factors of the packing, column internal play important role on scale-up effect of packed column.
