| Abstract | A half linear scale surface model of a downhole separator was tested, using geothermal water, to investigate effects which might prevent attainment of equilibrium in the flashing fluid. The device has moderate turndown but shows sharply reduced efficiency at very high vapour fractions. A reasonable estimate of the performance of a full sized separator is near 80% phase separation efficiency. The flashing process is rather slow, and results in a steam separation that is lower than might be expected from pressure drop calculations. phases at near the published equilibrium values. is distributed between the two |
