Toll Distillation at AVTA

AVTA operates laboratory and pilot plants at its site in Charlotte, NC. AVTA carries out toll distillation for heat sensitive and high melting products.

Short-Path and Wiped-Film Technologies are used for:

• Distillation of products which can only be distilled at a very high temperature under atmospheric pressure and where distillate and residue has to be discharged from the distillation in a very short time
• Reaction and/or distillation where heat sensitive products are feedstock, product or side product (e.g. vitamins)
• For thermal reactions that will run very quickly at high temperature and do not allow long residence time in the reactor
• For products with a tendency to spontaneously decompose

Feedstock
Ranging from low viscosity to high viscosity products
