Thyssenkrupp Industrial Solutions' subsidiary Uhde Inventa-Fischer has signed a contract to build two new world-scale polymer plants for SASA Polyester Sanayi A.Ş in Adana, Turkey.
One plant is planned to produce 380 kilotonnes per annum (ktpa) of PET (polyethylene terephthalate) for low-viscosity applications, while the second plant will use Uhde Inventa-Fischer's MTR technology to produce 216 ktpa of resin for the production of PET bottles.
The Essen, Germany-based Thyssenkrupp announced on 30 Nov that the two plants will be among the largest single-line production facilities for their respective products.
“Our… MTR process provides our customers with optimised energy consumption, maximum utilisation of feedstocks and effective plant operation, thus significantly reducing the total conversion cost compared with conventional technologies,” said Werner Steinauer, CEO of Uhde Inventa-Fischer commenting on the two contracts awarded to his company.
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) which helps save energy ‘substantially', according to Thyssenkrupp.
“It reduces investment, operating and maintenance costs, has a higher raw material yield and results in products of superior quality,” the company added.
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 high-quality polyester polymer.
A characteristic feature of the plant, according to Thyssenkrupp, is that the polymer melt will be conveyed directly from the polycondensation plant to several downstream lines.
The two contracts follow a €150m project Thyssenkrupp undertook last year in Russia, as part of which it is building a new PET polymer and polyester fibres complex for Russia's Polyester Ivanovo.
The facility, which will have an annual production capacity of up to 200ktpa, is currently being built in the Ivanovo region, 250km northeast of Moscow.
