Abstract

The current study aimed to evaluate the mass transfer parameters for the dissolution of spherical urea particles in fixed bed with downward flow of water. The impact of several operating parameters (particle size, height of the bed, liquid flow rate) on the key mass transfer parameters was investigated in isothermal conditions and atmospheric pressure. It was found that the mass transfer coefficient and urea dissolution degree increases by flow rate increase and decreases with the increase of particle size and bed height. The experimental values of the mass transfer coefficients were in good agreement with the ones found in the literature and the ones predicted by the Cussler equation.
