CONTINUOUS METHOD OF HYDROGEN DETERMINATION IN WATER

摘要

The design concerns the continuous method of determination of hydrogen especially in the cooling medium of the primary circuit of nuclear power plants and it does not require calibration by gas standards with hydrogen content. The introduced goal is achieved with the use of indirect determination of hydrogen that is separated from the cooling medium by the stripper gas (air, or mixture of air with nitrogen) from the values of oxygen depletion in the stripper gas, which is used up for catalytic incineration of hydrogen. Oxygen depletion is determined with the use of the oxygen analyser (4), which is equipped with an oxygen sensor with the solid electrolyte with oxygen ionic conduction and which is located in the set consisting of the stripper (1), vessel with a catalyser (2) and gas dehydrator with a cooling spiral (3). The signal of the oxygen sensor, responding by the thermodynamic relation, is processed by means of computer technology, which can at the same time control the activity of the analyser. The design can be used in all fields where it is needed to determine hydrogen that is soluble in water, water solutions or other liquids.<IMAGE>
