TRADE SHOW PREVIEW 79 PET planet insider Vol. 14 No. 09/13 www.petpla.net MRS extruders put to work A complete extrusion line and an MRS 160 Extruder with a throughput of 1.4t/h will represent Gneuss’ Multi Rotation System (MRS) extrusion technology. The extru- sion line consists of an MRS 130 Extruder, and RSFge- nius 200 and an RSFgenius 250 fully automatic filtration system. The line has a tandem filtration system to enable it to process up to 1,000kg/h of PET bottle flake directly into continuous filament, which requires 25 micron filtra- tion. Also on the stand will be an RSFgenius M, which has been developed especially for highly contaminated materi- als. The SFXmagnus R includes integrated self-cleaning of the filter elements for the first time in the series. www.gneuss.com Gneuss Hall 9 Booth A38 Cost reduction in PET production As the price for PET continues to fall, the production cost pressure for PET polymerisation and PET recycling continues to grow. BKG Bruckmann and Kreyenborg claims that with its the CrystallCut pelletising system (Mün- ster, Germany) offers an effective way to reduce these costs. At an average energy cost of 12 cents/kWh, energy savings of up to €15/t can be achieved. Today’s PET polymerisation plants can achieve a production capacity of 600t/day.With a throughput of 600t/day annual savings of approximately 26,000MWh can be achieved. Extrusion lines which recycle PET bottle flakes and have a produc- tion capacity of 1,500kg/h can achieve savings of more than 180kWh. Furthermore, due to the crystallisation of the pellets from the inside to the outside, a better crystalline structure is achieved which in turn will save on the costs/ energy to remelt the material. The CrystallCut system utilises the thermal energy of the melt for crystallisation. The melt is granulated by means of an underwater pel- letiser and reduces the residence time in the water to a minimum. The outlet temperature of the pellets after the dryer is already at required crystallisation temperature of 160-180°C. With this temperature, the pellets can be fed directly to the subsequent process. www.kreyenborg.de/en/ BKG Bruckmann & Kreyenborg Granuliertechnik GmbH Hall 9 Booth A44 A48 / 55 / A57
