INSTALLATION FOR INVESTIGATION AND METHOD OF INVESTIGATING EFFECT OF POROUS MEDIA ON PHASE BEHAVIOUR OF LIQUID AND GASEOUS FLUIDS Russian patent published in 2016 - IPC G01K17/06 

FIELD: measuring equipment.

SUBSTANCE: group of inventions relates to thermodynamics and can be used for the purpose of calorimetric measurements. Apparatus for investigating effect of porous media on phase behaviour of liquid and gaseous fluids comprises two calorimetric cells, each of which is surrounded by two adiabatic covers and is placed in appropriate vacuum container. According to disclosed method, in one of calorimetric cells analysed porous medium sample is placed, in which specific surface area is preliminary determined. Then identical samples of analysed fluid simultaneously placed in both calorimetric cells, after which measured simultaneously thermodynamic parameters of fluid in both calorimetric cells. Derived data diagram is plotted change phase of analysed fluid and as result of comparing obtained phase diagrams are evaluated effect of analysed porous medium on analysed fluid.

EFFECT: broader functional capabilities, as well as high accuracy and reliability of calorimetric measurements.
