NNLC083 - Small Scale Calciner Off Gas System

Tender description

NNL's Small Scale Calciner (SSC) system has suffered from repeated breakdowns and finally, due to a number of mechanical issues, the SSC was declared unfit for operation. NNL are now looking to replace this capability. Previous iterations of the SSC off-gas system were known to have issues with efficiency, dust build up in the pipes and condensation collecting in the fan therefore a replacement system is required. The SSC system comprised of a calciner unit and an off-gas scrubbing unit. Non-active Highly Active Liquor simulant is fed to a rotary furnace where it is dried and converted to powder containing a combination of metal nitrates and oxides (calcine). Off gasses produced are drawn into the building ventilation system passing through an off-gas scrubbing unit. This tender is for the off-gas treatment unit only.
