Note(s): Three different sizes of axial flow scrubbers packed with LiOH were tested in this study. The C02 concentration in the chamber for each test was monitored. The observed co. profiles were compared with that generated from a computer model. This analytical model was based on a one-dimensional and isothermal packed bed which was previously developed in this laboratory. The breakthrough time at 0.5% co. concentration for both observed and computed were within 5%. The deviation tends to be higher with scrubbers having smaller (L/D) ratios. At the end of each test, exhausted LiOH from different sections of the scrubber were taken and analyzed with a gasometric device to determine the effectiveness of co. absorption capacity. Approximately 0.56 g C02 /g of LiOH throughout the packed bed was obtained for most of the testings. The effectiveness of LiOH utilized was about 61%.
