“…A 3D model was presented by Gesit et al [21] for predicting the flow patterns and hydraulics of the sieve tray by a CFD device, utilizing the association of Colwell [22] for the liquid holdup working well in the force direction. A 3D CFD simulation was presented by Teleken et al [23][24][25] with the mathematical homogeneous biphasic model, for evaluating the effect of the electrical resistance of heaters over the sieve tray surfaces and its hydrodynamics. Moreover, Teleken et al [23][24][25] assessed the flow of a falling liquid film in a distillation column via an Eulerian-Eulerian CFD technique.…”

“…Recent advances in CFD modeling make it possible for three-dimensional (3D) simulations of complex multiphase flows in columns. Some studies on sieve tray with CFD models have been reported [4][5][6][7][8] to investigate the cross-current two-phase flow in distillation columns. But for the counter-current flow in ripple tray column, there is no research carried out until now.…”

“…O conhecimento sobre a hidráulica do estágio é fundamental para a predição do equilíbrio e comportamento da destilação, sendo necessários para o desenvolvimento de equipamentos sofisticados como as colunas de destilação (LI et al, 2009). Além das condições de operação da coluna (ZHANG et al 2000(ZHANG et al , 2003WEST, 1952) e das variações do sistema de destilação e reação (TELEKEN et al, 2009(TELEKEN et al, , 2010, estudo referentes ao contato das fases, à hidrodinâmica e ao comportamento do sistema encontram-se relacionados à hidráulica do prato de forma empírica (KISTER, 1992;SZULCZEWSKA et al, 2003) A configuração da RD (zona reativa, holdup, número de pratos, pressão, temperatura, refervedor e condensador) foi desenvolvida a partir de dados propostos na literatura aberta (WILLIAM, 2005), através de pesquisas sobre comparações entre sistemas de destilação extrativa e pressure-swing na recuperação do metanol no processo de produção de TAME e estimativa de parâmetros para o cálculo das propriedades físicas do biodiesel (Aspen Plus V9®). A reação para os dois sistemas é desenvolvida na fase líquida para o equilíbrio de conversão e a reação é descrita no simulador na forma cinética power-low para o estado estacionário.…”
