Chementator: New software should speed up reaction engineering

Simulations of chemical processes that involve many reactants with continually changing compositions can be set up and run in minutes, rather than the previously required hours, with a newly commercialized software package, Reaction Engineering Lab, says developer Comsol (Stockholm, Sweden,…

Minimize Trapped Components in Distillation Columns

Minor components trapped in distillation columns can react to form solids that cause major problems. The conventional responses to this situation focus upon dealing with the solids after they have become formed. A better strategy consists of preventing or minimizing…
