ABSTRACT:

The order of magnitude scaleup of the SRC-II Demonstration Plant Dissolver from the pilot plant units introduced uncertainty in hydrodynamic behavior and its impact on process performance. This led to an extensive program to study hydrodynamic parameters such as gas holdup, backmixing, and mass transfer. Cold flow bubble column experiments provided data for testing generic models at conditions representative of those expected in a dissolver. On-line radiotracer studies of the Ft. Lewis SRC Pilot Plant were conducted to verify projected hydrodynamic behavior in an operating environment. Finally, mathematical models were developed for simulating the performance of large scale reactors. All of these programs reinforced a general perception that the hydrodynamic behavior of the large SRC-II reactors will be complex, and not readily characterized by simple flow models. A conservative design philosophy and identification of viable contingencies to deal with hydrodynamics uncertainty will be necessary for first generation plants. 29 references, 19 figures, 9 tables.
