Sulzer DX

In this section of the studies, the flow patterns of two-phase flow in the investigated packings (monoliths, Sulzer DX , and Sulzer katapak S ) are discussed. Further, the resulting residence time distribution (RTD), flooding limits, and mass transfer behavior are compared. 

In a second set of experiments, different monolith types - Sulzer DX -packings and katapak-S - were tested under varying gas flow rates in countercurrent operation. The scatter of the data points in Fig. 8.24 was caused by the slightly changing water concentrations in the organic liquid. 

The potential of structured packings as catalyst carriers for reactive stripping, film-flow-monoliths, Sulzer DX -packings, both coated with zeolite BEA, and katapak-S , filled with BEA-particles, was explored in cold-flow experiments and under reactive stripping conditions in a pilot-scale plant. 

Both the absorber and stripper are columns in which commercial high surface area structured packing material, currently Sulzer DX, is installed. The cold rich stream from the absorber and the hot lean solvent from the stripper or MGD module are heat exchanged. Temperature profiles along the absorber and stripper can be measured. In total 7 pressure, 19 temperature, 5 gas flow, 2 liquid flow and 2 sump sensors are installed and logged. Samples can be... 

In the present work, the mass transfer performance characteristics of MEA-CO2 and DETA-CO2 systems in terms of the volumetric overall mass transfer coefficient (AgOv) were investigated. By means of determination of KqO, it is simple and effective to describe the mass transfer behavior of any solvent in the packed column. (Aroonwilas and Tontiwachwuthikul, 1998) [1] and Maneeintr et al, 2010 [6]) have successfully adopted this method to study the mass transfer performance for CO2 absorption into 2-amino-2-methyl-l-propanol (AMP) using Sulzer EX structured packing and into 4-diethylamino-2-butanol (DEAB) using Sulzer DX structured packing, respectively. Lastly, the predictive correlations of Kqu, for CO2 absorption into aqueous solutions of MEA and DETA were developed. The predicted Ag v results were then compared with the experimental results in terms of absolute average deviation (AAD). 

Sulzer katapak-S were developed for use in reactive distillation, though their use for trickle bed operations [18, 19] and as catalyst carrier in bubble flow columns [20] has also been investigated. Like DX, these packings consist of corrugated sheets made from wire gauze. Every second channel between the corrugated sheets is closed to form a tea bag which is filled with catalyst particles (Fig. 8.13). Therefore, voidage (ca. 40 %) and surface area (440 m2 m-3) are approximately half of those for the DX.
