in this investigation, the performance of a tower for absorption of sulphur dioxide gas into calcium carbonate solution has been studied. the trays had no downcomer and the tower itself was a scaled down pilot from industrial equipment. the industrial scale tower was used for clean up of 110000 m3/hr gas using 40 m3/hr alkaline solution. the study was composed of two parts. in the first section...

Though sulphur has long been recognized as an essential element in plants, particularly as a constituent of the proteins, it has not received much consideration in fertilizer studies. As shown by the work of HART and PETERSON (3), this was partly due to the older practice of determining sulphur in the ash of vegetation, which gave low results and did not indicate the true sulphur needs of the p...

The absorption of sulphur dioxide in chloride and bromide containing electrolyte solutions was measured up to ionic strengths of 5 mol/dm. The thermodynamic equilibrium of the gas phase and the liquid phase was characterized by UV spectroscopy. UV spectra analysis gave strong evidence for SO2X complexes existing in the solutions. Consequently, these compounds were implemented in the reaction sc...

A concise one dimensional thermal-hydraulic two-fluid model is presented for the numerical prediction of sulphur dioxide absorption from the flue gas onto drops of the water-limestone slurry in the vertical spray tower absorber. The model is based on mass, momentum and energy balance equations for each phase separately, i.e. downward falling droplets of water-limestone slurry and upward flowing...
