Raschig Super‐Pak – Eine neue Packungsstruktur mit innovativen Vorteilen im Vergleich

Die Raschig Super‐Pak ist eine neue Packungsgeometrie, die durch eine innovative Struktur über drei wesentliche Vorteile gegenüber anderen Hochleistungspackungen verfügt: niedrigere Druckverluste, höhere Kapazitäten, bessere Trennleistungen. Die bei der SRP (Separation Research Program) der Austin University of Texas vermessenen Leistungsdaten werden präsentiert und im Vergleich zu anderen Hochleistungs‐ und Standardpackungen bewertet.     

Rate‐based‐Modellierung von CO2‐Absorptionskolonnen mit Anstaupackungen

The efficiency of columns for fluid separation can be increased by the application of sandwich packings. During the operation, different load‐dependent regimes with peculiar separation performance arise. In order to account for the effects of the individual flow regimes in a single model, both separation performance measurements and tomographic imaging are applied. A rate‐based model is presented, which takes the heterogeneous regimes in sandwich packings into account by means of appropriate correlations. The model is tested with experimental data for CO₂ absorption.     

200 Jahre Entwicklung in der kontinuierlichen Destillation

Distillation is the oldest and today most frequently used separation and purification method. In 1813, Jean‐Baptiste Cellier‐Blumenthal patented the first continuously working distillation column, starting an impressive development of process equipment. New product areas were discovered as well as improved equipment installations. Current developments are guided by deeper knowledge of heat and mass transfer as well as the integration of various process functions.
