以雙攪拌釜為實驗設備，研究了煙氣脫硫過程中硫酸鈉、硫酸鎂和腐殖酸鈉對石灰石的促溶作用。結果表明，分別采用3種不同添加劑時，pH值等隨脫硫反應時間的變化規律類似；與非強化石灰石脫硫過程對比，在相同pH值下，3種添加劑均使石灰石顆粒體積占初始體積的分率rp減小，即均能促進石灰石的溶解，改善漿液的傳質性能。通過理論分析，導出了rp與漿液pH值之間的關系式，該方程能很好地關聯雙攪拌釜實驗數據。

Forced oxidation of calcium sulfite aqueous slurry is a key step for the calcium-ba sed flue gas de sulfurization (FGD) re sidue. Experiments were conducted in a semi-batch system and a continuous flow system on lab scales. The main reactor in semi-batch system is a 1000ml volume flask. It has five necks for continuous feeding of gas and a batch of calcium sulfite solutionPaqueous slurry. In continuous flow system, the main part is a jacketed Pyrex gla ss reactor in which gas and solutionPaqueous slurry are fed continuously. Calcium sulfite oxidation is a series of complex free2radical reactions. According to experimental re sults and literature data, the reactions are influenced significantly by mangane se as catalyst. Atlow concentration of mangane se and calcium sulfite, the reaction rate is dependent on 115 order of sulfite concentration, 015 order of mangane se concentration, and zero order of oxygen concentration in which the oxidation is controlled by chemical kinetics. With concentrations of calcium sulfite and mangane se increa sing, the reactions are independent gradually on the constituents in solution but are impacted by oxygen concentration. Mangane se can accelerate the free-radical reactions, and then enhances the mass transfer of oxygen from ga s to liquid. The critical concentration of calcium sulfite is 01007molPL, mangane se is 10-4 molPL, and oxygen is of 012-014atm.

Ag+-exchanged resins are prepared and studied for ethylene/ethane separation by adsorption. On Ag+-exchanged S9, at 25℃ and 0.1013MPa, the equilibrium adsorbed amount for C2H4 is 0.992mmol.g-1, and the adsorption ratio for C2H4/C2H6 is 3.56. The adsorption capacity can be restored almost completely at 25℃ and 75℃, and the desorption residual amount is less than 0.01mmol.g-1. For the adsorption consisting of physical adsorption and 7r-complexation with energy heterogeneity, the equilibrium data are correlated with Langmuir-FYeundlich isotherm equation. Furthermore, the heat of adsorption and the overall diffusion time constants are calculated from the experimental data. Considering all the adsorption characteristics, the application potential for industrial adsorption process is discussed.

The flow field of gas and liquid in a ф150mm rotating-stream-tray (RST) scrubber is simulated by using computational fluid dynamic (CFD) method. The simulation is based on the two-equation RNG k-ε turbulence model, Eulerian multiphase model, and a real-shape 3D model with a huge number of meshes. The simulation results include detailed information about velocity, pressure, volume fraction and so on. Some features of the flow field are obtained: liquid is atomized in a thin annular zone; a high velocity air zone prevents water drops at the bottom from flying towards the wall; the pressure varies sharply at the end of blades and so on. The results will be helpful for structure optimization and engineering design.
