An Experimental Investigation of Reactive Absorption of Carbon Dioxide into an Aqueous NH3/H2O/NaOH Solution
In this research, the reactive absorption of carbon dioxide in an aqueous solution of NH3, H2O, and NaOH has experimentally been investigated. The experiments were carried out in an absorption pilot plant in different operational conditions. The composition and temperature of both gas and liquid phases were obtained during the column height. The concentration of molecular ...
متن کاملULTRASONIC INVESTIGATIONS OF MnSO4, NiSO4 AND CuSO4 AQUEOUS IN POLYVINYL ALCOHOL SOLUTION AT 303K
Ultrasonic velocities and densities have been measured for the aqueous solution of manganese sulphate, nickel sulphate and copper sulphate in polyvinyl alcohol solution, in different concentration at 303K. Adiabatic compressibility, intermolecular free length, acoustic impedance, surface tension and other acoustical parameters have been calculated to assess the polymer-ion interaction. It is se...

of an internal rotation; the greater time for the carbon compound indicates some frictional resistance to rotation. Both dimethoxy compounds have similar relaxation times, as also have the tetramethoxy compounds. The greater size and substantially higher dipole moments of the silicon compounds, however, should produce a proportionately greater contribution from the molecular tumbling motion. Th...

The ultrasonic amlfiiLudc absorl)liou coelhcient has Iveen determined in aqueous solutions of four molecular weights (73 000, 186 000, 370 000, and 2 {DO 000) of dextran, a linear • (! --• 6) anhydroglucoae polysaccharide of biological origin, over the frequency range 3-69 Mc/sec at 22øC. It is found that the concentrationfree absorption spectrum exhibits a remarkable similarit)' to that of aqu...
متن کاملprediction of optimum time for oxygen clearance in solution polymerization of vinyl acetate in isopropyl alcohol
as we know oxygen is one of the main inhibitors of polymerization of vinyl acetate. therefore, nitrogen is used in order to make sure of system's high purity. to maintain purity it is necessary to find out the rate of the oxygensolution in polymerization system under different conditions of polymerization. it is concluded that incoming nitrogen to the system would remove the oxygen from th...
