Product and Process

According to the customer required products and capacities, AQUAFIL Engineering is offering batch as well as continuous polymerization plants. The plants can be equipped as a single stage or two stage polymerization process. The Lactam Direct Recycling Process (LDR®) is one of the key features of AQUAFIL Engineering. The plants can be designed for capacities up to 200 mt/d per line for continuous lines up to 6 mt/d per batch for discontinuous lines.

LDR^® Process

AQUAFIL Engineering is able to design the Caprolactam Recovery System according to the request of the customer. The most efficient and world wide unique Caprolactam Recovery System is the development of AQUAFIL Engineering which is called LDR® process (Lactam Direct Recycling).

The LDR^® process combines the advantages of:

• 100 % Caprolactam usage due to total recycling of extractable
• low energy cost
• simple plant design and operation
• no process waste water
• no 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 it is requested, instead of direct recycling, the concentrate can be polymerized in a separate polymerization line for the production of engineering plastics.
