Application of gamma-ray attenuation technology in density measurement of a slurry reactor

Jian XU, Weisheng WEI, Kai ZHANG

Frontiers of Chemical Science and Engineering 2010, Volume 4, Issue 4,   Pages 486-490 doi: 10.1007/s11705-010-0509-6

Abstract: Axial density profile of the gas-liquid-solid mixture in a slurry bubble column was measured by gamma-raySeveral measures for improving measurement precision were presented based on the discussion on attenuationfound that the response frequency and the ray intensity should be as high as possible to improve the measurementThe results showed that the density in the column decreases with the increase of column height, whichindicates that the measurement by gamma-ray attenuation is reasonable.
