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.

The inherent nonlinearities in the kinetics and heat transfer models of biomass pyrolysis have led to the applications of various numerical methods in solving the nonlinear problems. However, in order to have physical insights into the phenomena and to show the direct relationships between the parameters of the models, analytical solutions are required. In this work, approximate analytical solu...

Modeling and computational simulation of the carbon monoxide oxidation process, taken as a key system to analyze importance dynamic description active sites into process yield, are presented in this work. To aim, formalism transport phenomena population balances used implement realistic model that involves heat exchange, transfer mass momentum, chemical reaction, catalyst deactivation. The is s...

in the present work, the interaction of three water soluble porphyrins, tetra (p-trimethyle) ammoniumphenyl porphyrin iodide (tapp) as a cationic porphyrin, tetra sodium meso-tetrakis (p-sulphonatophenyle) porphyrin (tspp) as an anionic porphyrin and manganese tetrakis (p-sulphonato phenyl)porphinato acetate (mntspp) as a metal porphyrin, with dna have been studied by isothermaltitration microc...

The mixture of ionic liquid (1-butyl-3-methylimidazolium tetrafluoroborate, bmimBF4) and water (2.5%, molar fraction) under isothermal conditions at 80 degrees C was investigated by FTIR spectroscopy and two-dimensional correlation infrared spectroscopy (2D-IR) methods. Three regions were focused: the OH stretching band of water (3755-3300 cm (-1)), the stretching band of CH on the imidazole ri...
