Tradionally phase holdup distribution images of the flow system by a suitable reconstruction process

الملخص EN

Dynamic three phase reaction and process systems are used widely in the chemical, petrochemical and biochemical industries.

Dual Source Gamma ray Tomography (DSCT) has the potential for use as a noninvasive tool for determining the phases’ holdup distribution.

Most of the dual source gamma ray and X-ray tomography methods reported in the literature use low energy gamma ray photons.

These have poor penetration depths, thereby limiting their application to very small flow domains (~ 3in).

However, since most flow domains are large, the use of higher energy gamma ray photons is inevitable.

In this study, the 661 keV photon from Cs-137 and the 1332 keV photon from Co-60, have been explored for imaging phase holdup distribution in a gas-liquid-solid (GLS) system.
