aqueous vapor
1.Using calcite as raw material,adding ZrO 2 by wet chemical method,dropping Cr 2O 3 by vapor diffusion method,hydrating light calcined calciun oxide by aqueous vapor and eliminating the crack formed during sintering,the high purity hydration resistance calcium oxide refractory was developed with CaO content of>98%,bulk density of 3.25g/cm 3, cold compressive strength of>150MPa and increase in weight of<1% due to hydration in atmosphere for 60 days.
2.Under the UV radiation, Hg2+ in aqueous solution can be converted into Hg0 cold vapor by using an organic reactant of low molecular weight alcohols, aldehydes or carboxylic acids, namely, methanol, formaldehyde, acetaldehyde, glycol, 1,2-propanediol, glycerol, acetic acid, oxalic acid or malonic acid.
4.Vapor-Liquid Equilibrium Study on Ternary Aqueous Solutions of Volatile Weak Electrolytes——NH_3-CO_2-H_2O,NH_3-H_2S-H_2O andNH_3-SO_2-H_2O Systems
5.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.
