Изобретение относитс к области автоматического контрол состава трехкомпонентиых систем и может быть использовано в лабораторных и промышленных услови х.The invention relates to the field of automatic control of the composition of three-component systems and can be used in laboratory and industrial conditions.
Известны многопараметрические методы анализа многокомпонентных систем, заключающиес в одновременном измерении нескольких (дл трехкомпонентных систем - двух) различных физико-химических параметров смеси: удельной электропроводности и плотности, плотности и коэффициента преломлени , скорости ультразвука и в зкости, поглощени и отражени излучени и других сочетаний , - с последующим определением состава по заранее проградуированным диаграммам или математическим путем.Multiparameter methods for analyzing multicomponent systems are known, consisting in the simultaneous measurement of several (for three-component systems — two) different physicochemical parameters of the mixture: conductivity and density, density and refractive index, ultrasound and viscosity speed, absorption and reflection of radiation, and other combinations, - with the subsequent determination of the composition of pre-calibrated diagrams or mathematically.
Недостатком многопараметрических методов анализа состава вл етс невысока точность определени концентрации составл ющих компонентов из-за наличи различных датчиков с разным классом точности.The disadvantage of multiparameter analysis methods of composition is the low accuracy of determining the concentration of the constituent components due to the presence of various sensors with different accuracy classes.
Цель изобретени - повышение точности анализа трехкомпонентных систем и обеспечение возможности применени такого анализа при комплексной автоматизации производства.The purpose of the invention is to improve the accuracy of the analysis of three-component systems and to ensure the possibility of applying such an analysis in the integrated automation of production.
Цель достигаетс тем, что по предлагаемому способу состав трехкомпонентных систем легколетучих веществ определ ют путем одновременного измерени скорости ультразвука вThe goal is achieved by the fact that according to the proposed method, the composition of three-component systems of volatile substances is determined by simultaneously measuring the speed of ultrasound in
системе, например в смеси Н2О-(С2Н5)2О- CsHsOH, при двух заранее выбранных давлени х , например, Pi 0 и кг/см, наход т графически зависимости скорости ультразвука от концентраций вход щих компонентов при этих давлени х, затем на участок диаграммы Гиббса, ограниченный в данном случае концентрационными пределами Н2О 92-100%, СдНбОН 0-4%, (С2Н5)2 0-4%, нанос т линиии равных значений скорости ультразвука при выбранных давлени х.The system, for example in a mixture of H2O- (C2H5) 2O-CsHsOH, at two pre-selected pressures, for example, Pi 0 and kg / cm, graphically determines the ultrasound velocity on the concentrations of the incoming components at these pressures, then to the plot Gibbs, limited in this case by the concentration limits of H2O of 92-100%, CdNbON 0-4%, (C2H5) 2 0-4%, plotted lines of equal ultrasound speeds at selected pressures.
Р1золинии при PI O кгс1см изображают сплошными лини ми, а при кгс/см - штриховыми.P1 zeros with PI O kgc1cm are depicted as solid lines, and for kgf / cm - with dashed lines.
Точка пересечени изолиний дл двух выбранных давлений и определ ет состав смеси.The intersection point of the isolines for the two selected pressures determines the composition of the mixture.
