Micro Scale Prediction of the Roller Compaction Process ...

2010-04-01  The key factor in roller compaction is that the binding of particles results from the compression forces alone. The choice of powder to be compacted is therefore critical. Some active ingredients can be compressed directly. Others may be processed in combination with another material, which is selected for its favorable compaction properties.

High Pressure Boilers: Meaning, Types, Characteristics Advantages Thermodynamics

As at critical pressure steam and water co-exist at the same density and no bubble formation occurs. Further at critical pressure the enthalpy of evaporation (Latent heat) is zero. The water thus gets converted into steam directly without passing through evaporation process. It is a high pressure, water tube, forced circulation boiler.
