thyssenkrupp Uhde’s subsidiary Uhde Inventa-Fischer signed a contract to build three new world-scale polymer plants for SASA Polyester Sanayi A.Ş in Adana, Turkey. One plant is planned to produce 1,050 metric tons per day (380,000 tons per year) PET (polyethylene terephthalate) for low viscosity application combined with a Co-PET plant with a capacity of 100 metric tons per day (36,000 tons per year). The third plant will use Uhde Inventa-Fischer’s proprietary patented MTR® (Melt-to-Resin) technology to produce 330,000 tons per year of resin for the production of PET bottles.
The MTR® process eliminates the SSP (solid-state polycondensation) and leads to substantial energy savings. It reduces investment, operating and maintenance costs have a higher raw material yield, and results in products of superior quality. The MTR® process is based on Uhde Inventa-Fischer’s proprietary 2-Reactor technology which uses the patented ESPREE® and DISCAGE® reactors to obtain the desired high melt viscosities.
The design of the polycondensation plant will be based on the same proprietary technology, which in this case enables the production of the superior-high-quality polyester polymer. A characteristic feature of the plant is that the polymer melt will be conveyed directly from the polycondensation plant to several downstream lines.
