Special Issue Information

Dear Colleagues,

A multiphase system is characterized by the simultaneous presence of several phases, the two-phase system being the simplest case. The term two-component is sometimes used to describe flows in which the phases comprise different chemical substances. The analysis of multiphase systems can include consideration of multi-compound materials, multiphase flow, and multiphase heat and mass transfer.

The present Special Issue of Energies, entitled “Practical and Scientific Aspects of Multiphase Systems”, invites contributions on multiphase flows, multi-component systems, and chemical reactors of both experimental and computational studies. The Issue is focused on recent advances in conjunction to various practical aspects of chemical engineering, especially those related to the process intensification, process design, practical applicability of rheology, control systems, process safety, plant design, chemical technology, environmental engineering, materials, etc. We welcome communications, original research articles and review articles.

Granulated chelates are innovative fertilizers that are highly effective and versatile, and they ensure the best start-up effect for plants. The final properties of granules are influenced by the method of their preparation and the used substances. The diameters of the obtained granules, their size range, and the final costs of the produced fertilizer are of great importance. The paper describes granules that were produced using an agglomeration of ZnIDHA in a fluidized bed with the aid of an aqueous solution of this substance with a high dry matter content. The aim of the study was to evaluate the effect of surfactant addition to the solution on the evolution of granule size distribution during the process carried out in a batch mode and to access the possibility of describing the process dynamics using population balance approach. A sieve analysis was performed in order to determine the size of the granulate, and numerical calculations were performed to determine the value of the constant aggregation rate. Based on experimental studies, it can be seen that the increase in the diameters of granules is mainly caused by the agglomeration process, and to a lesser extent by the coating process. The addition of surfactant increased the median size of the granules in the initial granulation stage, and also lowered the surface tension. This in turn enables a lower spraying pressure to be used. A comparison of different aggregation kernels constituting an integral part of the population balance model proved that the physically motivated equipartition kinetic energy kernel performs best in this case. Moreover, the computational results show an increase in the aggregation rate when the surfactant additive is used and confirm that population balance allows the extraction of physical information about the granulation.
