Title: Theoretical and experimental analysis of a multiphase screw pump, handling gas-liquid mixtures with very high gas volume fractions

Abstract

In the investigation of the pumping behaviour of multiphase screw pumps, handling gas-liquid mixtures with very high gas volume fractions, theoretical and experimental analyses were performed. A new theoretical screw pump model was developed, which calculates the time-dependent conditions inside the several chambers of a screw pump as well as the exchange of mass and energy between these chambers. By means of the performed experimental analysis, the screw pump model was verified, especially at very high gas volume fractions from 90% to 99%. The experiments, which were conducted with the reference fluids water and air, can be divided mainly into the determination of the steady state pumping behaviour on the one hand and into the analysis of selected transient operating conditions on the other hand, whereas the visualisation of the leakage flows through the circumferential gaps was rounded off the experimental analysis.

  • The relativist approach to the interpretation of measurements in multiphase systems was proposed in order to incorporate the details of measurements into theoretical analyses of multiphase transport processes. To help establish the utility of this approach, the weight functions for actual experimental probes must be determined. In this paper the authors analyze the measurement of liquid-phase porosity in a model system by nuclear magnetic resonance imaging. They show how both nuclear magnetic resonance (NMR) physics and experimental technique combine to determine the weight function for the spin-warp spin-echo sequence. The analysis shows clearly what aspects of the weight function aremore » determined by the experimental method and what aspects are determined by the system being studied. The results will help establish the utility of the relativist approach as well as improve understanding NMR measurements in multiphase systems.« less
  • The equations were developed to describe adsorption from multicomponent ideal liquid systems on homogeneous or heterogeneous solid surfaces yielded predictions of the adsorbed-surface-phase composition that agreed satisfactorily with experimental data for the n-heptane/cyclohexane/benzene, n-heptane/cyclohexane/toluene, and n-heptane/cyclohexane/p-xylene ternaries on silica gel at 20/sup 0/C.
  • This paper presents the results of an experimental investigation of pressure distribution inside working chamber of a twin screw compressor for multiphase duties. A mathematical model for describing the pressure distribution inside working chamber is proposed. By means of a small pressure transducer embedded into the groove at the root of the rotor, the pressure distributions of a multiphase compressor under various running conditions have been recorded successfully to verify the model. It is found that the pressure curve during the discharge process has a higher level under the conditions of the lower gas void fraction, higher discharge pressure, highermore » rotational speed and higher inlet pressure. The pressure distribution calculated by model in this paper shows good agreement with the data recorded by a small pressure sensor in a prototype multiphase compressor at the high gas void fractions under different operating conditions.

  • The Solar Liquid Piston Pump (SLPP) is driven by oscillations of an enclosed column of liquid Freon 113. Cyclic evaporation and condensation from heating and cooling coils at the top of the liquid column generate the oscillations. The frequency and amplitude of the oscillations are enhanced by momentum forces in the inlet, outlet, and working tubes. Three geometrically different experimental models of a SLPP have been tested. To optimize the performance of the SLPP, a theoretical model was required to account for the large number of interdependent parametres that could be varied. A semiemperical time-incremented computer model was developed. Amore » theoretical cycle was assumed and the heat transfer and fluid friction coefficient adjusted, within reasonable limits, so that the theoretical pressurevolume diagrams agreed closely with experimental ones. Input parameters were then varied for the theoretical model and compared to experimental results available. The theoretical model successfully predicted performance trends of the SLPP.« less
  • A multiphase flowmeter (MPFM) installed offshore Egypt accurately measured three-phase flow in extremely gassy flow conditions. The meter is completely nonintrusive with no moving parts, requires no flow mixing before measurement and no bypass loop to remove gas before multiphase measurement. Flow regimes observed during the field test of this meter ranged from severe slugging to annular flow. Average gas volume fraction ranged from 93 to 98% during tests conducted on 7 wells. The meter was installed in the October field in the Gulf of Suez on a well-protector platform and was placed in series with a test separator locatedmore » on a nearby production platform. Production was routed through both the MPFM and the test separator simultaneously. Flow conditions ranged from 1,300 to 4,700 B/D fluid, with 2.4 to 3.9 MMscf/D and water cuts from 1 to 52%. The MPFM measured gas and liquid rates to within {+-} 10% of test separator reference measurement flow rates at gas volume fractions from 93 to 96%. Accuracy deteriorated at higher gas volume fractions, but the meters provided repeatable results.« less
