Although it is known that a loss in separation performance caused by liquid maldistribution, there only marginal knowledge of distribution rotating packed beds (RPBs). As result, the exact influence on RPBs not fully understood. Therefore, this study focuses different distributors hold-up metal foam packing inside RPBs. Liquid hold-ups were measured noninvasively using γ-ray computed tomography (CT), and water/air was system under investigation, operated at atmospheric pressure, temperature...
Rotating packed beds (RPBs) are increasingly used in academia and industry for separation processes, but a lack of knowledge about fluid dynamics liquid maldistribution still limits our understanding the mass transfer inside. Recently, structured Zickzack packings (ZZ packings) were designed that promise to provide homogeneous distribution throughout packing volume. In this study, water–air system ZZ characterized at atmospheric pressure 20 °C. For decreasing rotational speeds, strongly...
Recently, various internals for rotating packed beds (RPBs) have been developed. However, the technical maturity of these is still relatively low compared to packings columns. In this work, a novel design proposed RPBs, consisting seal structure combined with Zickzack packing. The around packing was developed avoid bypasses in spaces between and inner rotor walls, comparable wall wipers used structured This applied deaeration experiments using water nitrogen as stripping gas at rotational...
A method for pressure drop prediction using Computational fluid dynamics (CFD) was designed and validated experimentally with a set of baffle-based geometry types Rotating Packed Bed's packings. The methodology served as foundation CFD optimisation tool internal based on minimal drop. baffles in the were characterized by five parameters: bottom top rounding, external baffle inclination angle. Based variables, 78 different created subjected to tool. optimal manufactured, simulation results...
