Numerical study of boundary layer injection as a scale control method

Description: A boundary layer injection method of controlling scale-buildup in geothermal two-phase flow nozzles is studied. The object of this study is to set an upper limit on the ratio of the injected mass flow rate to the free stream mass flow rate that is necessary to isolate the scale carrying free stream flow from the nozzle wall. In order to develop a numerical model of the boundary layer flow, assumptions are made which reduce the results to order of magnitude approximations. Two configurations of … more

Investigation of a perfusion impaction dust separator

Description: Collection efficiency of an impaction dust separator with a porous plate as the impaction surface was investigated theoretically and experimentally. To provide continuous removal of deposited material, water perfused through the plate in a direction opposite to the impaction direction. The determination of theoretical collection efficiencies as a function of particle and jet properties was attempted by analyzing the governing equations. Experimental collection efficiency was measured for an aer… more

Processing of radioactive waste solutions in a vacuum evaporator- crystallizer

Description: Results of the first 18 months' operation of Hanford's vacuum evaporator- crystallizer are reported. This process reduces the volume of radioactive waste solutions and simultaneously converts the waste to a less mobile salt cake. The evaporator-crystallizer is operating at better than design production rates and has reduced the volume of radioactive wastes by more than 15 million gallons. A process description, plant performance data, mechanical difficulties, and future operating plans are disc… more
