“…The effect of bed voidage on mass transfer factor has been observed and considered by many previous investigators (Sengupta and Thodos 1962, Wilson and Geankoplis 1966, Couderc et al 1972, Damronglerd et al 1975, Laguerie and Angelino 1975, Dwivedi and Upadhyay 1977, Rahman and Streat 1981a, Shen et al 1985, Wildhagen et al 1985, Seguin et al 1996. Sengupta and Thodos (1962) and Wilson and Geankoplis (1966) have shown that mass transfer factor is inversely proportional to bed voidage.…”

“…Shen et al (1985) have reported the exponent value as 0.27, which is quite similar to the results obtained by Laguerie and Angelino (1975), who have found the exponent of superficial liquid velocity equal to 0.217. Kikuchi et al (1988) have shown that MTC is proportional to superficial velocity raised to 0.196 power, while Seguin et al (1996) have found the value equal to 0.33. It would be worthwhile to mention that few investigators (Damronglerd et al 1975, Tournie et al 1979, Ballesteros et al 1982, Livingston and Noble 1993 have observed that MTC is independent of superficial liquid velocity.…”

“…Few reports are also available in the literature wherein MTC is directly related to superficial liquid velocity (Evans and Gerald 1953, Laguerie and Angelino 1975, Shen et al 1985, Kikuchi et al 1988, Seguin et al 1996, Boskovic-Vragolovic et al 2005. Evans and Gerald (1953) have reported that MTC increases with an increase in superficial mass velocity raised to 0.33 power.…”

AbstractSolid-liquid circulating fluidized beds (SLCFBs) offer several attractive features over conventional solid-liquid fluidized beds such as efficient liquid-solid contact, favorable mass and heat transfer, reduced back-mixing of phases, and integrated reactor and regenerator design. These unique features have stimulated theoretical and experimental investigations over the past two decades on transport phenomena in SLCFBs. However, there is a need to compile and analyze the published information with a coherent theme to design and develop SLCFB with sufficient degree of confidence for commercial application. Therefore, the present work reviews and analyzes the literature on hydrodynamic, mixing, heat transfer, and mass transfer characteristics of SLCFBs comprehensively. Suitable recommendations have also been made for future work in concise manner based on the knowledge gaps identified in the literature. Furthermore, a novel multistage SLCFB has been proposed to overcome the limitations of existing SLCFBs. The proposed model of SLCFB primarily consists of a single multistage column which is divided into two sections wherein both the steps of utilizationviz.loading (adsorption, catalytic reaction, etc.) and regeneration of solid phase could be carried out simultaneously on a continuous mode.

The sulfonation of solid acrylonitrile‐butadiene‐styrene, a feedstock that is often used in the 3D printing process of fused filament fabrication, and its application in characterizing liquid‐solid mass transfer is reported. The ion‐exchange capacity was assessed experimentally, and intraparticle diffusion coupled with extraparticle liquid‐solid mass transfer was simulated. Tubular reactors and spherical particles were fabricated by 3D printing, modified by sulfonation, and used to determine mass transfer coefficients for laminar flow in a tubular reactor and a fixed bed of spherical particles. The results show good agreement with published correlations and demonstrate the applicability of this cost‐effective, accurate, and reliable method.

This work is focused on the analysis of the scale‐up process of styrene drying by adsorption onto activated alumina as a necessary step in the manufacture of styrene–butadiene rubber. In a previous work, the mathematical model was developed and the design parameters were estimated from the fitting of the model to experimental results obtained in a laboratory set‐up. The obtained model and parameters have been used to simulate the behaviour of a pilot plant that contains up to 56 times more sorbent stating their validity after comparison with experimental results. Finally, the behaviour of an industrial plant presently at work, was also satisfactorily described. The ability of the model to simulate experimental results obtained on three different scales checks its adequacy for process design and optimization. © 2002 Society of Chemical Industry
