“…[39] [42]. Bu bağlamda, incelenen modellerden absorpsiyon sistemleri için Onda [39] yaklaşımları, damıtma sistemleri için Bravo-Fair [24], Senol [41] ve Billet [7] modelleri, modern dolgu maddesi yapıları için Wagner [9] modeli ve Hanley'in basınç düşüşü [43] ve kütle transferi [44] bağıntıları ve en gelişmiş yapıdaki dolguların kullanıldığı üç evreli buhar-sıvı-sıvı damıtma uygulamaları için de Chen [18] yaklaşımları en güvenilir sonuçlar vermektedir. Çalışmada değerlendirilen modellerden film teorisi kökenli tasarım yaklaşımlarının benzeri penetrasyon mensuplu olanlarınkine kıyasla daha başarılı sonuçlar verdiği aşikardır.…”

Various geometrically constructed packings and plates are commonly used as separating tools in distillation columns since they possess different mass transfer efficiency due to their shape and surface properties. The strategic design factors required for the selection of a proper distillation column have been analyzed on the basis of a large literature data bank and the operating properties of relevant contacting tools have been compared. In the design practice, the mass transfer interfacial area, the efficiency, the pressure drop and the vapor capacity are the most promising factors that need to be characterized. In view of these design factors, the common design models covering plate devices, and random and structured packings have been discussed. The evaluated packed column design models are generally dependent on the film or penetration theory. In this regard, the predictive performances of the most useful models for the packed column design have been compared. Here, the main goal is placed on the description of the confidence levels of packed column design models. These common design approaches are presented in the relevant tables.

“…The vapor-side mass transfer coefficient is also based on a penetration model, and the theoretical time interval is determined by the length of the flow path, the superficial gas velocity, and the liquid holdup. Hanley et al (1994b) proposed models for mass transfer coefficients and available area available for mass transfer based on electrical percolation on an insulator/conductor lattice. Rocha et al (1996) improved and updated the SRP (I) model and proposed the SRP (II) model, in which they made modifications on characteristic dimensions of packing, effective gas and liquid velocity, and contact time.…”
