Flue Gas Desulphurization (FGD) Chemistry Course
Introduction:
During the combustion of certain fuels, sulfur dioxide (SO2) is emitted, which can have detrimental effects on the environment, such as acidification. To mitigate these harmful effects, a flue gas desulfurization process is commonly employed to clean the flue gas. Among the various flue gas desulfurization technologies used in power production, the wet flue gas desulfurization process (wet FGD) is the most widely adopted.
In the wet FGD process, SO2 is absorbed into a slurry that contains limestone. As a result of the reaction between limestone and the absorbed SO2, gypsum is produced. Gypsum is a valuable by-product that finds applications in the production of wallboard and cement.
Our research on wet FGD focuses on the fundamental aspects of the process, complementing the more empirical approach typically followed by the power plant industry. By conducting this fundamental research, we aim to support and enhance the traditional methods employed in the power plant industry.
Course Objectives:
This training course is designed to give the participants the competence to:
- Mathematical modeling of the wet FGD process in general
- The effects of limestone type and particle size on cleaning efficiency
- The effects or organic buffers in the wet FGD slurry
- Foaming and defoaming in wet FGD plants
- Simultaneous absorption of HCl and SO2
- Full-scale measurements
- Crystallization of gypsum
- The effects of oxyfuel combustion on wet FGD
- Jet bubbling and falling film wet FGD pilot plant reactors
Who Should Attend?
This training course is ideal for lab and quality professionals that do not have formal training or experience flue gas or those that want to refresh their current knowledge. It is also suitable for Environmental Quality Personnel, and fiscal quality inspectors.
