thyssenkrupp Industrial Solutions’ subsidiary Uhde Inventa-Fischer has signed a contract to build two new world-scale polymer plants for SASA Polyester Sanayi A.S in Adana, Turkey.
One plant is planned to produce 1050 tpd (380 000 tpy) of polyethylene terephthalate (PET) for low-viscosity applications. The second plant will use Uhde Inventa-Fischer’s MTR® technology to produce 216 000 tpy of resin for the production of PET bottles. Both new plants are among the largest single-line production plants for their respective products.
Werner Steinauer, CEO of Uhde Inventa-Fischer, commented: “We are very proud that SASA chose us to build another two state-of-the art PET plants after we were already contracted to build one of the largest polyester lines last year. Our commercially tried-and-tested MTR process provides our customers with optimized energy consumption, maximum utilisation of feedstocks and effective plant operation, thus significantly reducing the total conversion cost compared with conventional technologies.”
The scope of delivery for both projects will include basic and detail engineering, the delivery of all necessary components, and technical services for erection, pre-commissioning and commissioning supervision.
The MTR process eliminates solid-state polycondensation (SSP) 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 process is based on Uhde Inventa-Fischer’s proprietary 2-reactor technology, which uses the 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. A characteristic feature of the plant is that the polymer melt will be conveyed directly from the polycondensation plant to several downstream lines.
