Abstract

Method and apparatus for obtaining a sample of the liquid component of steam and determining the quality of steam in a vessel or the like, such as steam flowing in a line used for steam injection in an oil well. The steam quality is determined by the known method of comparing the concentrations of dissolved solids in the liquid sample and the feedwater. A sample of the liquid phase of steam is trapped in a liquid vapor separator maintained at steam line temperature and pressure conditions. In this way errors due to condensation in the separator and its connecting lines are avoided. The sample is withdrawn from the separator into a collection chamber at a controlled rate which avoids reducing the pressure within the separator and thereby avoids the introduction of error because of erroneous concentration of dissolved solids within the separator sample. Errors are avoided also which in other methods and devices are introduced by the difficulty of obtaining representative two-phase samples and by deposition of solids in throttling orifices.
