Working with the customer, AVN constructed and operated a pilot-scale system to demonstrate a process for production of bio-based acrylonitrile. The unit was operated continuously and used to generate data for design of a larger-scale system. Acrylonitrile product was collected and purified to demonstrate the ability to meet specifications. –… Read More

A customer needed to determine the feasibility of recovering acrolein from an aqueous product stream. AVN investigated the separation at the lab scale in a distillation column constructed of 1-inch Oldershaw sections, equipped for continuous feeds, including inhibitors. The required column design and operating conditions were determined, and the data… Read More

AVN was approached by a company that wanted to evaluate several possible routes to a desired product. AVN assembled a multidisciplinary team to perform an initial technology assessment in collaboration with the company. Work began with a literature and technical study to develop an initial perspective on the chemistry feasibility… Read More

AVN collaborated with a company who was developing fixed bed catalyst technology for a new process. Initial screening and catalyst selection had been completed, but there was a need to focus on kinetic modeling and bench-scale reactor testing to gain understanding about reactor geometries and key independent variables and their… Read More

A company had been operating a process that was not originally developed to produce a solid product. The product needs had changed, and the company wanted assistance with controlling the process to consistently produce crystalline product with the desired crystal morphology and size distribution. AVN devised and carried out a… Read More
