AVN successfully screened a raw material from a new supplier for use in production of a flame-retardant product.  AVN replicated the existing process with the existing raw materials utilizing a heated reactor, distillation equipment, and product washing procedures.  AVN then repeated the process with the material from the new supplier,… Read More

 A 300 mL Parr reactor was operated at 2500 psi (172 bar) and 300°C to satisfy a customer’s scoping needs. AVN assembled a pressure feed system using a Haskell compressor and surge cylinder. This process was used to help the customer narrow future optimization efforts over a ten-batch designed set… Read More

During scale-up efforts at AVN, a customer encountered problems with heavies accumulating within their renewable process. AVN used a pilot-scale wiped-film evaporator (WFE), deep vacuum skid, and heating oil unit to operate at 0.1 Torr and 300 °C. The equipment was tested independently of the full process, then integrated into… Read More

A customer wanted to purify bio-based material to support their future lab studies.  AVN constructed a continuous glass vacuum distillation system to separate the desired product from light and heavy components to a final purity of 99.99%. The column was assembled using existing AVN equipment and left in place for… Read More

Following successful small-scale demonstrations of reactions between specialty epoxides and selected nucleophiles, the customer requested larger quantities of the resulting products for further evaluation. AVN assembled appropriate reaction apparatus and conducted the syntheses as needed, delivering the desired product volumes to support ongoing testing efforts.  – For additional information, contact questions@AVNcorp.com… Read More
