EXTERNAL DIFFUSION KINETICS OF MASS TRANSFER. FEATURES OF KINETICS OF ADSORPTION

Integrated Technologies and Energy Saving, 2020
The external diffusion stage of mass transfer in systems with a solid phase was analyzed. The equations of external diffusion kinetics are presented for mass transport from the volume of a liquid to the surface of a solid phase (crystallization, adsorption, ion exchange) and from the surface of a solid to a liquid (dissolution, extraction, drying ...

Ozone mass transfer and kinetics experiments [PDF]

, 1981
Experiments were conducted at the Hanford Site to determine the most efficient pH and temperature levels for the destruction of complexants in Hanford high-level defense waste. These complexants enhance migration of radionuclides in the soil and inhibit the growth of crystals in the evaporator-crystallizer.

Modelling the Mass Transfer Kinetics of Battered and Breaded Fish Nuggets during Deep-Fat Frying at Different Frying Temperatures

Journal of Food Quality, 2020
Battered and breaded fish nuggets (BBFNs) were fried at three different temperatures (160, 170, and 180°C) for 30–180 s to study the mass transfer kinetics of moisture loss and fat absorption.
