Aquafil Engineering is one of the worldwide leading companies in technology and equipment design and construction for polyester and polyamide polymer plants for the fiber, packaging and plastic industries.
The design for polyester and polyamide is based on Aquafil Engineering-patented technology and production knowhow that provide customers with the latest state-of-the-art technology combined with high quality, flexibility, efficiency and sustainability.
Aquafil Engineering has research capabilities and can run tests at its own pilot and industrial scale plants before entering the customer market. The technologies allow low conversion costs to produce high quality items that make the producer competitive in the global market.
Aquafil Engineering is a member of the Aquafil Group, the European market leader in Nylon 6 yarns for BCF flooring and No.2 worldwide. Aquafil has also gained significant experience in engineering plastics and special textile fiber segments.
Polyester
The Aquafil 2-reactor polyester technology with the unique and patented UPR reactor has already been used in nine production plants and has become the most proven and reliable 2-reactor technology in the market. With this design, it is possible to set up units with high flexibility, reasonable price and up to 600 t/d in one line.
The polymer is used for different applications like filament direct spinning, film direct casting (DFC), film via chips, bottles via chips and tirecord via chips. All these PET- products are well accepted in the market.
The latest innovation of Aquafil Engineering is the “Low Building Technology” (LBT) polycondensation. The LBT plant fits into a hall and does not require any difficult building structures. This way the customer can considerably reduce the building and erection cost and time. Additionally, the LBT plant achieves the lowest electrical consumption worldwide compared to standard plants. The first LBT plant is under erection in the US.
Nylon
Further, according to the customer required products and capacities, Aquafil Engineering is offering batch as well as continuous polymerization plants, designed for capacities up to 250 t/d per line for continuous lines and up to 6 t/d per batch for discontinuous lines. The plants can be equipped as a single-stage or two-stage polymerization process.
The most efficient caprolactam recovery system is called LDR (Lactam Direct Recycling). Since 2004 the largest single polymerization plant (150t/d) with LDR technology is very successfully in operation in China. At the moment the company is erecting two new PA6 lines (China and East Europe) with the latest development, which is called Aquafil High Quality LDR (HQ LDR).
The HQ LDR process combines the advantages of 100 per cent caprolactam usage due to total recycling of extractable, low energy cost, simple plant design and operation, nil process waste water and nil air pollution.
The process is available for all polymer qualities, even for high quality polyamide products like tire cord, film, foil and high performance textile yarns. If requested by a customer, it is also possible (instead of direct recycling) to polymerize the recovered lactam concentrate in a separate polymerization line for production of engineering plastics.
Aquafil Engineering also offers customer-specific services related to modernization and optimization of existing facilities, including analysis of the actual chemical and physical process of the plant (with proprietary software for PET as well as for PA, it is tailor-made to solve the specific plant problems); consultancy for trouble removal, concerning trouble in quality, quantity, technology or equipment; support and organisation of plant overhauls, plant maintenance or plant stops and starts; and feasibility studies.
