PET SSP leaN - floor mounted design
The SSP plant concept has been simplified for vPET and rPET plants with a throughput up to 300 t/d. All process equipment is mounted on the floor and does not require a special building.
The SSP reactor can be placed directly next to the end product silos outside the building. This SSP leaN process meets POLYMETRIX's high SSP process standards in terms of product quality, functionality and reliability.
The SSP leaN process starts with a combined process step of crystallization and preheating and can be operated with both spherical and cylindrical granules. After preheating, the PET pellets are conveyed hot, subjected to the SSP reaction and cooled. Nitrogen from the process is continuously cleaned by a catalytic combustion or an ethylene glycol gas scrubber. For rPET plants, a new type of guard bed has been integrated into the process gas purification to better eliminate foreign contaminants released in the recycled material during SSP process.
