Development of a three phase fraction meter. Quarterly report, June 1983-August 1983
The simulation routines developed and outlined in the previous quarterly report were expanded to investigate the performance of different combinations of nuclear gauges that would respond to changes in the phase fractions of the process stream at the SRC1 facility in Wilsonville. The gauges investigated were: high energy gamma gauge with (I) cesium 137 and (II) barium 133 source; low energy gamma gauge (americium source); and neutron gauge (californium source). The Dual Energy Gamma Gauge (DUEGG) combination was shown to give the most accurate results (10 to 20% error for ash fraction, 0.5 to 2% for liquid and 2 to 7% for gas fraction using a cesium source), the neutron-high energy gamma combination giving good accuracy for the gas and liquid fractions (2 to 10% and 1 to 5% relative error respectively) but showing poor accuracy for the ash fraction (50 to 75%). Use of all three gauges together gave no improvement over the DUEGG combination in the simulation. Each combination was investigated for slug and dispersed flow regimes and for pipe diameters of 1'' (currently used at Wilsonville) and 10''. The results reported in the quarterly report of February through May were for 2'' pipe diameter. The barium response was slightly better than the cesium giving relative errors of 14 to 20% in ash fraction, 0.4 to 0.8% in liquid fraction and 4 to 6% in gas fraction compared with the results quoted above for cesium in the DUEGG configuration. The experimental work performed using a bench scale laboratory set up incorporating a DUEGG was completed; the results obtained for varying ash fraction confirming once again the validity of the theoretical techniques used in the simulation routines. Some mechanical design work was performed, in particular in the areas of source sizing, thermal insulation and blind hole calculations. 2 refs., 5 figs., 7 tabs.
