packing coefficient
1.Absorbing acetic acid in air or waste gas by distilled water, acetic acid in distilled water was detected by gas chromatography with packed column of 5% PEG 20M and 0?5% H?3PO?4 on chromosorb HP 80～100 mesh packing? This method is simple and rapid? The variable coefficient is between 2% and 5%, recovery of added standard is between 85% and 106%, detecting limit is 0?16mg/L?
2.The setup of adiabatic absorption of vapor into lithium bromide aqueous solution was de- signed and established. Experimental study on absorption performance of the adiabatic absorber with structured packing was conducted. The influence of solution flowrate,solution temperature,solution concentration,and vapor pressure on coefficient of mass transfer was analyzed.
3.The author of the paper preliminarily inquires into the effect of gas velocity, superficial liquid velocity, static bed height, density of packing ball, and the area of a single packing ball surface on the pressure drop across the bed, height of bed expansion, outlet co_2-content, desorption efficiency, and the mass transfer coefficient K_L.
