A new route to a desired product was conceptualized by a customer, but it was not certain whether the process would be practical. Several process steps were involved, one of which included continuous addition of butadiene. AVN demonstrated all of the process steps and showed that each step could be… Read More

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
