METHOD OF DETERMINING DEW POINTS IN GASES WITH ANALYSIS OF CHEMICAL NATURE OF CONDENSED SUBSTANCES AND APPARATUS FOR REALISING SAID METHOD

摘要

FIELD: chemistry.;SUBSTANCE: disclosed is a method of determining dew points in gases with analysis of the chemical nature of the condensed substances, wherein the analysed gas is fed onto a cooled condensation surface and its temperature at the beginning of condensation is recorded, wherein the beginning of condensation of the substance on the condensation surface is determined by picking up proton resonance signals in a nuclear magnetic resonance spectrum using a nuclear magnetic resonance spectrometer; chemical nature of the condensed substance is determined from parameters of the proton resonance signals. Also disclosed is apparatus for realising the disclosed method, having a housing with openings for inlet and outlet of the analysed gas, a condensation surface, a cooler, a device for measuring temperature of the condensation surface and a nuclear magnetic resonance spectrometer.;EFFECT: method of determining dew points in gases with analysis of chemical nature of the condensed substances, having high accuracy, possibility of determining all dew points in the operating temperature range and chemical nature of the condensed substances, which does not require thorough cleaning of the gas, and a device for realising this method, which enables to conduct continuous flow analysis of gas and has low sensitivity to contamination of the condensation surface.;5 cl, 1 dwg
