PBT 3 Reactor Process
Well proven commercialized technology based on Raw Material PTA (DMT is expensive and availability limited)
Four successfully started up since 2000Demonstrated capacities up to 200 t/d– design capacity up to 500 t/d availableOne additional line under execution (start-up 2009)
Advantages of this processIV easily adjustable between 0.7 and 1.2 dl/gLow catalyst content resulting in better color and lower costsHighly efficient esterification stage for best conversionProven 2 stage THF recovery with > 99% purity

PBT Batch Process - General Design
This is the right process for the production of specialities
(high market products)
Disc Ring AutoclaveCapacities up to 120 t/day (single line) available with highest flexibility
Very fast adjustment of different viscosities without any transition material
Special designed Disc Ring Autoclave with polymer circulation
(‘finisher’ based on same principles as for continuous process)
Vacuum from max. 200 mbar to < 1 mbar
Extrusion of the batch under vacuum like in the continuous process
- 80 t/day Batch Line for PET (bottle grade and PET film) in operation
- 90 t/day Batch Line for special polymer will be started-up by Lurgi Zimmer in II/2009

Summary and View
Difficult market situation expected in this year
Development of cost efficient technologies even more important
Eco-friendly trend in the PET industry must also be factored into our thinking
RésuméFuture polyester plants having higher capacities will also need to be more compact, energy efficient and save spacePBT is an excellent polymer and meets the high requirement of the industry (especially compounding – engineering plastics – etc.)
