Senior Process Engineer
"Recent discoverer of DWSIM and really impressed so far; have started testing it on projects involving distillation, absorption, LLE, and looking forward to using it more regularly."
Director/Engineer
"The robustness and diversity of external solvers, along with the faster and more stable property packages, are noteworthy."
Scientific Researcher
"We successfully implemented the Amine Package after discovering that the old thermodynamic model was not functioning effectively. The results we obtained are highly comparable to those produced by other well-established process simulation software."
