| Abstract
| - The solubility of sulfur dioxide is measured in the seawater of the Arabian Gulf, which ischaracterized by large seasonal variations in temperature and high salinity. A literature reviewshows that this is the first investigation for measuring the SO2 solubility in the Gulf seawater.The measurements are motivated by the need for the solubility data in the design anddevelopment of efficient seawater flue gas desulfurization systems. Solubility measurementsare made as a function of the seawater temperature and salinity. Water samples include distilledwater, seawater, mixtures of distilled water and seawater, and brine blowdown from themultistage flash desalination plants in Kuwait. The SO2 solubility function has a second-orderdependence on the system temperature and initial salinity. Results show an increase in theSO2 solubility and the reaction rate at higher initial salinity. Higher solubility is measured atlow temperatures. Good agreement is also obtained between the measured data, literaturemeasurements, and predictions of the solubility model.
