Abstract: The system of apparatuses for obtaining of magnesium hydrogen carbonate is characterized by the fact that the water supply network is connected to the softening installation (3) by a pipeline through which are located a one-way cock (1) and a mechanical filter (2), such as the softening installation (3) consists of series-connected ion exchange columns with a capacity of 2 m3/h and which is directly connected to a tank (4) with a volume of 300 l, which is equipped with a level indicator (5) to read the filling level of the tank (4), such as the tank (4) is connected to the reactor (11) by a pipeline on which are located one-way cock (1), centrifugal pump (6), two-way cock (7), which allows part of the deionized water through a flexible connection to be used for washing, as after the two-way cock (7), before the flow meter (8), there is located a two-way cock (7), through which is realized a pipeline connection between the buffer tank (12) and the reactor (11), which is a airtight reactor-absorber, as in it is taking place the synthesis of magnesium hydrogen carbonate, as a result of the interaction between a magnesium compound (MgAx) and carbon dioxide in an aqueous medium, as the reactor (11) is equipped with: - with a connecting branch for connecting a cylinder (10) equipped with a reducing valve connected to a bubbler (18) for supplying the reactor (11) with carbon dioxide; - the mechanical stirrer (19); - pH meter (9); - a hatch located in the upper part of the reactor (11), which serves to add to the reactor (11) magnesium compound (MgAx) after filling it with the required stoichiometric amount of deionized water from the tank (4), and - a connecting branch through which unreacted CO2 is fed to the top of an airtight tank (13), wherein the airtight tank (13) serving as a collection point for the finished product is connected by a pipeline to a reactor (11) on which are mounted a two-way cock (7) pump, mechanical filter and one-way cock (1), as before the two-way cock on the pipeline is made a branch, on which is mounted a one-way cock (1), for sample taking during and at the end of the process from the reactor, as the airtight tank (13) is equipped with a manometer (14), throttle-valve for pressure regulation in the airtight tank (21), level indicator (5) and with a cooling system consisting of: - worm pipe in which refrigerant circulates; - circulating pump (16) and - a refrigeration unit (17) connected by a pipeline to the worm pipe in the airtight tank (13), wherein on the pipeline connecting the airtight tank (13) and the circulation pump (16) is located a thermocouple, and on the pipeline connecting the airtight tank (13) and the filling system is located a single-way cock (1), as on the pipeline is mounted a branch with one-way sampling cock, wherein the tank (13) via a pipeline on which are located in series a single-way cock (1) and a pump is connected to a buffer tank (12) with a volume of 200 l and serves to buffer the entire production circuit and through a two-way cock (7), a pump and two one-way cocks through a pipeline is connected to the reactor (11), as the connection between the two pipelines is made before the flow meter (8).
