Local and global measurements in trickle bed reactor, Part 1: Pressure drop and flow regime map

Shripad T.Revankar,XiangchengKong

A tricke bed test facility was designed and constructed with impedance based global bed void and liquid hold up measurement. Single phase flow and two phase flow characterization of the test loop was performed by air and water concurrent down flowin the bed. The flowregime in the bed was observed and recorded with high speed video camera. Flow regime map was developed. Five flow regimes were identified, trickling, wavy, transitional, pulsing and bubble flow. Pressure drop measurements in the bed were also obtained for various flow regimes in the bed. The data of the pressure drop and flow regime maps were compared with previous works and a good agreement was found between and present and pervious works.
