Thyssenkrupp Uhde’s (Dortmund, Germany) 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 (m.t.) per day polyethylene terephthalate (PET) for low viscosity application combined with a Co-PET plant with a capacity of 100 m.t./d. The third plant will use Uhde Inventa-Fischer’s proprietary patented MTR (Melt-to-Resin) technology to produce 330,000 m.t./yr of resin for the production of PET bottles.
Mustafa Kemal Öz, GM of SASA Polyester Sanayi A.Ş. says: “We are pleased to choose again Uhde Inventa-Fischer for our new investments. SASA is racing to global leadership in polyester production with its state-of-the-art world class production facilities. It is an honor to continue our cooperation with UIF who has been always a good business partner of our growth strategy.”
Werner Steinauer, CEO of Uhde Inventa-Fischer adds: “We are very proud that SASA chose us to build further state-of-the- art PET plants after we were assigned to build already Line 1, Line 2, and Line 3.” Scope of delivery for all plants includes basic and detail engineering, delivery of all necessary components, technical services regarding plant erection, as well as supervision of erection and commissioning.
The MTR process eliminates the SSP (solid-state polycondensation) and leads to substantial energy savings. It reduces investment, operating and maintenance costs, has 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 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.
