Opis:
Barbotage reactors such as airlift reactors (ALR) and bubble column reactors (BCR) due to their two-phase flow are the subject of many studies. Their basic version is used for lifting, mixing, and aeration of liquids, while their hybrid version, supplemented with additional elements, can serve as a rector for transport, lifting, and aeration of liquids. The subject of the research were two design variants of a hybrid barbotage reactor differing in the position of the nozzle for circulation and aeration, both filled with a moving bed. Based on the previously obtained measurement results, a simple mathematical equation was proposed to describe the impact of the type of construction and filling the hybrid reactor with a moving bed on the oxygen concentration and mixing conditions as well as on the transport of liquids. It was found that the greatest impact on the transport of liquid in the hybrid barbotage reactor (HBR) had the location of the H-nozzle, and filling the reactor with a moving bed had the greatest impact on the oxygen conditions and mixing of the liquid in the case of the HBR reactor.

Opis:
The paper presents different approaches to the proper and accurate production and modelling (multi- phase reaction) of CaCO3 formation in the most popular, different types of reactors, i.e. continuous reactor (STR – stirred tank reactors, MSMPR – mixed suspension, mixed product removal; tube reactor), a bubble column reactor and a thin film reactor. Many different methods of calcium carbonate production and their effect on the various characteristics of the product have been presented and discussed. One of the most important, from the point of view of practical applications, is the morphology and size of the produced particles as well as their agglomerates and size distribution. The size of the obtained CaCO3 particles and their agglomerates can vary from nanometers to micrometers. It depends on many factors but the most important are the conditions calcium carbonate precipitation and then stored. The experimental research was strongly aided by theoretical considerations on the correct description of the process of calcium carbonate precipitation. More than once, the correct modelling of a specific process contributed to the explanation of the phenomena observed during the experiment (i.e. formation of polyforms, intermediate products, etc.). Moreover, different methods and approaches to the accurate description of crystallization processes as well as main CFD problems has been widely reviewed. It can be used as a basic material to formulation and implementation of new, accurate models describing not only multiphase crystallization processes but also any processes taking place in different chemical reactors.
