Wet Granulation Technology vs. Slugging Technology vs. Roller Compaction Technology... 

Sizing devices are now trimly fitted to the compactor body and controlled by variable speed drives. Most compactors no longer require a second machine (mill) in tandem to size compacts as required by slugging technology. Roller compactors have clean-in-place (CIP) systems that offer environmental and safety features. These systems minimize human exposure to chemicals and improve cleaning efficiencies. Fig. 7.

A number of these attributes, best technology practices and features, were rated for their industrial and pharmaceutical importance and reported by Miller and Sheskey in 2001. Ultimately, today s roller compaction technology offers a continuous process with better process controls, manufacturing efficiencies, and environmental protection than an archaic slugging process technology. 

Classiflcations of Fluidization Behavior Geldart [Powder Technology, 7, 285 (1973)] and later Dixon [Pneumatic Conveying, Plastics Conveying and Bulk Storage, Butters (ed.). Applied Science Publishers, 1981] developed a classification of fluidization/aeration behavior from studies of fluidized beds and slugging in vertical tubes. 

How could scientific and technological challenges be overcome The main problems to be dealt with are to maintain the optimum formulation of the surfactant slug during the process and to improve the sweep efficiency of the main surfactant slug.

Later, the additional advantages described in Tab. 6.2-3 led to a quickly increasing use of the technology. To meet the industry s capacity requirements, slugging presses... 

These hmitations, which are associated with the use of molecular oxygen, might be overcome by the use of microreactor technology [7-15]. Due to their small inner dimensions, microreactors provide both high safety and enhanced process intensification [16-18]. The high surface-to-volume ratio properties of microchannels (inner diameter 100-1000 pm) are highly beneficial, especially for multiphase reactions. In addition to enhanced gas-hquid interfacial transfer, intense recirculation within the hquid slugs allows for fast renewal of the interfaces...
