INEOS Sulphuric Acid Converter

The construction of the new sulphuric acid converter at INEOS faced many challenges.  The new converter had to be constructed under absolute dry conditions with access available for materials to be craned in.  The plant was to remain operational whilst works took place, posing challenges with stability as the structure could not be tied to any adjacent structures or increased in any great width to prevent overturning.    

The solution consisted of a 26m high, free standing, fully clad scaffold with a removable roof.  Any stability that would be gained from the roof was lost.  To enable the structure to stay rigid, a radial shape with kentledge bays was designed.       

Throughout the process timing was critical as the plant was to be temporarily shut down at a pre-determined time for the transfer of converters.
