The synthetic pathway to the target product comprised several key steps: epoxidation using hydrogen peroxide, ethoxylation via reaction with ethylene oxide, and catalytic hydrogenation under elevated pressure. AVN assembled the necessary equipment and developed safety protocols to execute each stage effectively, successfully demonstrating the complete process at a large laboratory… Read More

A new process currently in development incorporates a reactive distillation concept aimed at dramatically enhancing both operability and cost-effectiveness. To validate the underlying assumptions, a demonstration was essential. AVN initiated laboratory experiments to collect preliminary data and used advanced process simulation tools to fine-tune the distillation column design, optimizing it… Read More

A company sought to assess the effectiveness of novel materials for removing carbon dioxide from mixed gas streams. To facilitate this, AVN developed a screening unit for single-pass evaluation of candidate materials, supported by precise analytical techniques to ensure accurate performance measurements. Initial testing yielded valuable data on capacity and… Read More

A customer wanted to test a novel concept involving vapor-phase contact of hydrocarbon mixtures with oxygen at elevated temperatures and pressures. To support this initiative, AVN designed and commissioned a lab-scale experimental unit capable of safely executing the process and monitoring reaction progress. Tests were conducted across varying reactant ratios… Read More

A company sought to enhance the yield of a liquid-phase catalytic process. To support this effort, AVN constructed a semi-batch laboratory unit and conducted extensive testing across a range of catalysts and operating conditions. Through these experiments, key factors influencing overall yield were identified, including the effect of recycling unconverted… Read More
