METHOD AND DEVICE FOR DETERMINATION OF SOLUTION CONTENT ON BASE OF TWO-COMPONENT FLUID AND COMPRESSED GAS Russian patent published in 2007 - IPC G01N7/00 G01N7/14 

FIELD: analysis of content of solution.

SUBSTANCE: method and device can be used for determination of mutual solvability of fluid and compressed gas. Solution is fed from piezometer along pipeline to flask and throttling process id performed by means of special gadget to reach atmospheric pressure, at which pressure the compressed gas loses its solvability and extracts from solution while other components are left in liquid or hard phase. Throttling unit is mounted in front of entrance of flask intended for solution. Flask is made of elastic and vapor-penetrable material. Volume of extracted gas is carried out due to measurement of volume of thermostatic fluid in flask, forced out of thermostat provided with overflow un it used for supplying solution into flask. Masses of solution components, left in flask in liquid or solid phase, are measured during time of τ when components change to vapor phase due to passing through walls of flask into environment. Content of solution component is determined by building graph and selecting linear part on it, which part is described by relation of m₂₊₃ - m/m₂₊₃=β+α*τ, where m₂₊₃ is initial mass of components mixture, left in liquid or solid phase; m is mass of component mixture of solution, which components are left in liquid or solid phase at moment time of τ; α is relative speed of transition to vapor phase, defined as tangent of angle of inclination φ of linear part to axis τ; β=m₃/m₂₊₃ is mass portion of more volatile component of solution, where m is mass of more volatile component, which is defined as part of straight line cut out of axis m₂₊₃ - m/m₂₊₃, when linear part of graph is extrapolated to it on base of dependence of m₃=β*m₂₊₃. Mass of volatile component m₂ is found from relation of m₂= m₂₊₃- m₃.

EFFECT: improved precision of measurement; improved truth of results.
