Abstract

The removal of trace components from gas streams via irreversible gas-solid reactions in an area of interest to lớn the chemical engineering profession. This research effort addresses the use of fixed beds of Ba(OH)/sub 2/ hydrate flakes for the removal of an acid gas, CO/sub 2/, from air that contains approx. 330 ppM/sub v/ CO/sub 2/. Areas of investigation encompassed: (1) an extensive literature Reviews of Ba(OH)/sub 2/ hydrate chemistry, (2) microscale studies on 0.150-g samples lớn develop a better understanding of the reaction, (3) process studies at the macroscale cấp độ with 10.2-cm-ID fixed-bed reactors, & (4) the development of a mã sản phẩm for predicting fixed-bed performance. Experimental studies indicated fixed beds of commercial Ba(OH)/sub 2/.8H/sub 2/O flakes at ambient temperatures khổng lồ be capable of high CO/sub 2/-removal efficiencies (effluent concentrations 99%), and an acceptable pressure drop (1.8 kPa/m at a superficial gas velođô thị of 13 cm/s). Ba(OH)/sub 2/.8H/sub 2/O was determined lớn be more reactive sầu toward CO/sub 2/ than either Ba(OH)/sub 2/.3H/sub 2/O or Ba(OH)/sub 2/.1H/sub 2/O. A key variable in the development of this fixed-bed process was relative sầu humidity. Operation at conditions with effluent relative humidities >60% resulted in significant recrystallization & restructuring of themore» flake & subsequent pressure-drop problems.«less
