  • HETP Evaluation of Structured and Randomic Packing Distillation Column
    3 HETP Evaluation of Structured and Randomic Packing Distillation Column Marisa Fernandes Mendes Chemical Engineering Department, Technology Institute, Universidade Federal Rural do Rio de Janeiro Brazil 1. Introduction Packed columns are equipment commonly found in absorption, distillation, stripping, heat exchangers and other operations, like removal of dust, mist and odors and for other purposes. Mass transfer between phases is promoted by their intimate contact through all the extent of the packed bed. The main factors involving the design of packed columns are mechanics and equipment efficiency. Among the mechanical factors one could mention liquid distributors, supports, pressure drop and capacity of the column. The factors related to column efficiency are liquid distribution and redistribution, in order to obtain the maximum area possible for liquid and vapor contact (Caldas and Lacerda, 1988). These columns are useful devices in the mass transfer and are available in various construction materials such as metal, plastic, porcelain, ceramic and so on. They also have good efficiency and capacity, moreover, are usually cheaper than other devices of mass transfer (Eckert, 1975). The main desirable requirements for the packing of distillation columns are: to promote a uniform distribution of gas and liquid, have large surface area (for greater contact between the liquid and vapor phase) and have an open structure, providing a low resistance to the gas flow. Packed columns are manufactured so they are able to gather, leaving small gaps without covering each other. Many types and shapes of packing can satisfactorily meet these requirements (Henley and Seader, 1981). The packing are divided in random – randomly distributed in the interior of the column – and structured – distributed in a regular geometry.

The experiments covered a wide range of pressures, two corrugation angles, two surface areas, and two surface designs. Experimental results include pressure drop, capacity, and mass-transfer efficiency. The database generated has been used to evaluate generalized performance models developed independently at The University of Texas Separations Research Program (SRP model)) and at Delft University of Technology (Delft model).

The models have been reported in the original form provided by the authors together with the geometric and model fitting parameters published in several papers to allow their adaptation to packings different from those covered in the original papers. Although the work is focused on a collection of carefully described and ready-to-use equations, we have tried to underline the criticalities behind these models, which mostly rely on the assessment of fluid-dynamics parameters such as liquid film thickness, liquid hold-up and interfacial area, or the real liquid paths or any mal-distributions flow.

Sc. Prof. Roberto Mauri Academic year 2015/2016 i Gran parte del progresso sta nella volontà del progredire. Seneca Il dizionario è l'unico posto dove successo viene prima di sudore. Vince Lombardi ii iii Abstract University of Pisa - Department of Civil and Industrial Engineering Master Thesis in Chemical Engineering Investigation of the fluid behavior in randomly packed columns using Computed Tomography Domenico Mangiaracina The qualitative investigation of the fluid behavior and the quantitative evaluation of widespread fluid dynamic parameters like liquid hold-up, wetted area and mass-transfer area in a randomly packed column are carried out using Computed Tomography CT, a totally non- invasive measuring technique. Despite the huge effort of different researchers, a lack of comprehension about the flow field within the packed bed still prevents the development of completely satisfying models, that are precisely able to predict these fluid dynamic parameters in order to achieve an economically optimized design of the column. In the present work, three commercial random packings (Raflux Ring, RMSR and RSR), belonging to different generations, are scanned in a 0.1 m diameter column in presence of two different systems: water / air and isopropanol /air. The latter is used for the first time in CT investigations despite the common industrial applications of these organic compounds. An algorithm, previously developed by Schug and Arlt.

    Previous Page 14-58 EQUIPMENT FOR DISTILLATION, GAS ABSORPTION, PHASE DISPERSION, AND PHASE SEPARATION For structured packing, Kister and Gill [Chem. Eng. Symp. Ser. 128, A109 (1992)] noticed a much steeper rise of pressure drop with flow parameter than that predicted from Fig. 14-55, and presented a mod- ified chart (Fig. 14-56). The GPDC charts in Figs. 14-55 and 14-56 do not contain specific flood curves. Both Strigle and Kister and Gill recommend calculating the flood point from the flood pressure drop, given by the Kister and Gill equation ∆ = 0.7 Pflood 0.12Fp (14-142) Equation (14-142) permits finding the pressure drop curve in Fig. 14-55 or 14-56 at which incipient flooding occurs. For low-capacity random packings, such as the small first-generation > −1 packings and those smaller than 1-in diameter (Fp 60 ft ), calculated flood pressure drops are well in excess of the upper pressure drop curve in Fig. 14-55. For these packings only, the original Eckert flood correlation [Chem. Eng. Prog. 66(3), 39 (1970)] found in pre-1997 edi- tions of this handbook and other major distillation texts is suitable.

Box 75169-13817, Iran; [email protected] 2 School of Chemical Engineering and Institute of LNG, College of Engineering, University of Tehran, Tehran P.O.

Different types of RPB, and their advantages and effects on hydrodynamics, mass transfer, and power consumption under available models, are analyzed. Moreover, different approaches to the modeling of RPB are discussed, their mass transfer characteristics and hydrody- namic features are compared, and all models are reviewed. A dimensional analysis showed that suitable dimensionless numbers could make for a more realistic definition of the system, and could be used for prototype scale-up and benchmarking purposes. Additionally, comparisons of the results demonstrated that Re, Gr, Sc, Fr, We, and shape factors are effective. In addition, a study of mass transfer models revealed that the contact zone was the main area of interest in previous studies, and this zone was not evaluated in the same way as packed beds. Moreover, CFD studies revealed that Citation: Ghadyanlou, F.; Azari, A.; the realizable k-" turbulence model and the VOF two-phase model, combined with experimental Vatani, A.
