What is the relation with Caprolactam?
Caprolactam, being the core product of DSM Fibre Intermediates has in its production process a side stream. This stream is used as an input in the ammonium sulphate plant at the Geleen site. Here we crystallize this fluid, we centrifuge, we dry and cool the product until TAS granulate is generated. TAS is produced in a dedicated environment, isolated from standard ammonium sulphate production. In a dedicated silo, TAS is temporarily stored before it is taken to the packaging process.
