A project being pursued with a customer produced a high-boiling mixture that needed to be separated by distillation to yield two separate products. AVN simulated the separation with Aspen Plus and designed the pilot-scale system to demonstrate the operation experimentally. The unit was operated to generate design data for larger-scale… Read More

A client was producing a crystalline product obtained through the reaction of several feed materials. The product had inconsistent properties resulting from varying crystal size and morphology. AVN designed a set of experiments to determine the effects of reaction and crystallization variables on product quality. Results from the study allowed… Read More

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
