A review on process intensification in HiGee distillation

Abstract

15This review paper describes the state-of-the-art in the field of HiGee contactors used for gas-16 liquid mass transfer processes, with a special focus on distillation, and for heterogeneously 17 catalyzed reactions. 18Several types of rotating beds are discussed, including single-block rotating packed-bed, split-19 packing rotating bed, rotating zigzag bed, two-stage counter-current rotating packed bed, 20 blade packing rotating packed bed, rotating bed with blade packing and baffles, counter-flow 21 concentric-ring rotating bed and crossflow concentric-baffle rotating bed. 22The working principles of HiGee technology, as well as the modeling, design and control 23 aspects, and practical applications are explained and discussed. In addition, this paper 24 addresses the advantages and disadvantages with respect to mass-transfer performance, 25 pressure drop, rotor complexity and suitability to perform continuous distillation and to be 26

Separation Units 4.0 – Trennapparate heute und morgen

“…Nachteilig sind die höheren Druckverluste im Vergleich zu konventionellen Packungen sowie die Notwendigkeit rotierender Teile zur Erzeugung der benötigten Zentrifugalkräfte. Die konstruktive Ausgestaltung sowie die Möglichkeiten der Phasenkontaktierung sind dabei vielfältig. Cortes Garcia et al geben einen Überblick über die verschiedenen Bauweisen und Anwendungsmöglichkeiten in der thermischen Verfahrenstechnik, die in der Literatur beschrieben werden.…”

Application of Supergravity Technology in a TEG Dehydration Process for Offshore Platforms

“…It is called "the transistor of the chemical industry". The principle of the Higee is shown in Figure 2 [5]. (2) Insufficient operation capacity of dehydration tower The TEG dehydration tower has a diameter of only 762 mm and a treatment capacity of 115 × 10 4 m 3 /d under full load conditions.…”

Modeling, Simulation, and Optimization 4.0 for a Distillation Column

“…Cyclic distillation requires specialized column trays while periodic operation of a binary distillation shows potential for some savings without changes of equipment. Besides this, there is still current research on improvement of mass transfer by development of new internals like for example using high centrifugal forces in rotating beds like in HiGee contactors or by using new production methods like additive manufacturing , which offer possibilities for new structures.…”
