Leaching mass transfer

Web5 sep. 2024 · Diffusion transport in fluids is always slower compared to convective transport. Convection is the transfer of massive fluid from one part to another, accompanied by both diffusion and advection. It dominates the diffusion rate because it occurs very slowly in liquids when measured in human length scales. WebThis course will provide an overview on mass transfer at basic to an intermediate level. This course applies the concepts of diffusion and interphase mass transfer to the analysis of different unit operations such as humidification, drying, adsorption,extraction, leaching, crystallization and membrane processes.
