Process intensification refers to technologies and strategies that enable simpler and more efficient processes compared to conventional processes. Some features of such intensified processes are less recycle streams, reduced need for waste handling and lower investment and operating costs compared to conventional processes. One way of doing this is by making two or more process steps simultaneo...

Considering the fact that students have different abilities to understand knowledge imparted by teachers, a multi-granularity distillation mechanism is proposed for transferring more understandable student networks. A self-analyzing module of teacher network designed, which enables learn from teaching patterns. Furthermore, stable excitation scheme robust supervision training. The can be embedd...

−− The aim of this work is to simulate and analyze an extractive distillation process (extractive distillation and recovery columns) for the separation of Tetrahydrofuran (THF)-Water azeotropic mixture using Aspen Plus® and Aspen Split simulators. Calculation of vapor liquid equilibrium of Tetrahydrofuran–Water–Entrainer system was done using the NRTL model, which binary interaction parameters ...
