Input Variable Selection in Modelling of Desulphurization Efficiency
Several methods are applied to find the input variables with predictive power to the degree of desulphurization modelling. The methods are applied on the data from a desulphurization plant processing flue gases coming from a coal-fired power plant. In non-linear and complex industrial processes, the nature of the relationships between the variables may be vague and a functional model based on a...
متن کاملThe capture of oxidized mercury from simulated desulphurization aqueous solutions.
Elemental mercury in flue gases from coal combustion is difficult to control. However, oxidized mercury species are soluble in water and can be removed with a high degree of efficiency in wet flue gas desulphurization (WFGD) systems operating in coal combustion plants, provided that no re-emissions occur. In this article the mechanisms affecting the re-emission of oxidized mercury species in WF...
متن کاملDynamics of wet flue gas desulphurization in spray absorber
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...
متن کاملThe Research on Desulphurization of an Iron Concentrate
Iron ore concentrate sales in a mineral processing plant appeared a trend of high sulfur, exceeding the sales requirement of 0.3% significantly. To this end, for the sulfide in iron concentrate mainly exists in the form of pyrrhotite, companies with iron minerals and has a high degree of oxidation, we can add flotation agent to the magnetic separation column, and at the same time fill gas for s...
متن کاملA Non-catalytic Deep Desulphurization Process using Hydrodynamic Cavitation
A novel approach is developed for desulphurization of fuels or organics without use of catalyst. In this process, organic and aqueous phases are mixed in a predefined manner under ambient conditions and passed through a cavitating device. Vapor cavities formed in the cavitating device are then collapsed which generate (in-situ) oxidizing species which react with the sulphur moiety resulting in ...
