ABSTRACT:

A study was undertaken to investigate the fluid dynamics of large scale bubble columns. A literature search was conducted in the first phase of the study, and subsequent phases were to devise and implement an experimental program to test specific design concepts and to offer recommended design improvements for the SRC-II Demonstration Plant dissolver. The literature search included review and analysis of existing knowledge in the areas of flow regime, gas holdup and mass transfer, backmixing and solids accumulation. It was found that a vast amount of literature exists on bubble column behavior; however, most studies have dealt with small laboratory size columns, and only a few extended studies to larger sizes. This report details the findings of the literature search. The subsequent phases of the study were not undertaken due to termination of the SRC project.
