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

A customer developing a new process sought support in evaluating and mitigating flammability hazards, particularly regarding the interaction of oxygen with organic liquids and vapors throughout the system. AVN provided expert guidance on potential explosion risks, including prediction of flammability limits and the impact of chemical conversion on hazard levels. Mitigation strategies were outlined,… Read More

AVN partnered with a customer on a collaborative initiative to design a pilot plant for producing a specialty polyolefin. The engineering phase focused on selecting suitable equipment—including a reactor, pumps, flowmeters, process control systems, and post-processing components—while also evaluating analytical techniques to support operation. A comprehensive design safety review was conducted to verify engineering controls for safe… Read More
