Absorption column

ZVU STROJÍRNY manufactured and at the end of 2016 dispatched a truly impressive product – an absorption column with 55.6 m in length, 4.4 m in diameter and a total weight of 290 tonnes. 

The column is a key component in the production of nitric acid and consists of 55 special levels where the acid is being absorbed. Because of the immense size, the column had to be made in two pieces, transported individually to the river port in Mělník where they were welded together into the final shape, subjected to a pressure test and sent along the river. The column with accessories was loaded on a ship measuring 7 x 7 x 58 m which took it to Hamburg. There it was loaded on a transoceanic ship bound for India where it arrived on 13 February 2017.
