RU2004904C1 - Device to take samples of liquids and vapors - Google Patents

Description

First, the autoclave closed with the sealer is filled with the test solution to the required volume. The amount of solution is selected experimentally so that, under experimental parameters, the interface between the liquid and the vapor is at the level of the middle glass. In this case, there will be steam in the upper glasses during sampling, the liquid in the lower glasses, and on average a mixture of these two phases. Before filling the autoclave, air is evacuated from it with a vacuum pump 12 with the valve 9 open and the vacuum valve 11 located in position 11a (Fig. 4). After evacuation, the valve switches to position 116 and a solution is sucked into the autoclave from the burette 10, the required amount of which is controlled by divisions on the burette. After filling the autoclave, the valve 9 shuts off the filling system from the autoclave-pressure gauge system. After that, the autoclave is placed in a vertical position in an isothermal furnace and displayed at the desired temperature. After bringing into operation and reaching equilibrium, the sample cups 20 are closed by squeezing them with a screw 14 through the stem 15 and the pusher 22. In this case, the gasket caps are expanded, pressed against the edges of the glasses and securely sealed. After

overlap the glasses the experiment ceases. The upper glasses contain steam. the lower ones are liquid. After the autoclave has cooled, pipeline 6 is disconnected, nut 5

it is turned away and the shutter is pulled out of the autoclave together with the sleeve 18 and the cups closed and turned over so that the sample cups are turned downside down. Sleeve

it is turned away and removed from the obturator. A pusher is first removed from it, and then the glasses are alternately pushed first with steam condensate, a mixture of condensate and liquid and a sample of liquid,

The proposed device allows

without disturbing the thermodynamic and chemical equilibrium, take several duplicate samples of liquid and vapor at elevated temperatures and pressures in

volume-calibrated beakers to determine the density of the phases to be studied by weighing the samples taken, as well as to determine the pH and chemical composition.
