For non-isothermal operation in plate type gas absorber, the temperature changes and number of ideal trays can be determined with recourse to graphical method. In this paper there is an analysis illustrating that a Modified Kremser Equation can be used for plate type gas absorber in non-isothermal operation.

Abstract This paper focusses on investigating and comparing the congruent crystallization of phosphate glasses with different degrees polymerization. The study was performed both powders, size fractions, coarse particles which can be assimilated to bulk. From DSC experiments, corroborated by SEM analysis, it demonstrated that LiPO3 crystallizes from surface whereas LiGe2(PO4)3 in whole volume. ...

Transparent Y3Al5O12-based polycrystalline ceramics with excessive Al2O3 composition (Al2O3-26 mol%Y2O3, AY26) have been demonstrated as potential host materials for phosphor applications. However, the crystallization mechanism of AY26 glass has not thoroughly investigated so far. In this work, non-isothermal kinetics was experimentally analyzed. The depicts high activation energy and volume nu...

The matched asymptotic (singular perturbation) treatment of the nucleation equation [V. A. Shneidman, Sov. Phys. Tech. Phys. 32, 76 (1987); 33, 1338 (1988)] is modified to include finite heating rate effects, which follow the isothermal transient stage. Despite the complicated mathematical structure of the discrete Becker-Doring equation, the obtained analytical solution is shown to be accurate...
