Divided-Wall Columns (DWC)
Distillation columns is one of the most energy intensive equipment in chemical and petroleum industries. The separation of ternary mixtures usually is accomplished by the classical sequence of two distillation columns. Interestingly, according to Ling e Luyben (2009), the Divided-Wall Columns (DWC) can reduce the energy costs in up to…
Understanding equation-oriented simulators
There are essentially two process simulator technologies: modular (sequential) and equation-oriented (simultaneous). In this video (in Portuguese) some of the advantages of the equation-oriented approach are shown for the iiSE simulator.
