Semiwet scrubbing: Design and operational experience of a state‐of‐the‐art unit

Abstract

Semiwet scrubbers are used for the removal of acid components from flue gases in a variety of thermal processes. The focus of this study is application of the

Insight into the interaction between amino acids and SO2: Detailed bonding modes

“…Traditional methods to remove SO2 from flue gas include: wet flue gas desulfurization (WFGD), dry adsorption technology 4 , semi-dry and semi-wet desulfurization. 5,6 However, all of these methods suffer from high installation cost, high energy consumption, and the presence of large amounts of waste liquids, which has prompted researchers to seek new methods. A number of new methods have been proposed so far, such as catalytic redox 7,8 , adsorption on porous media (e.g., activated carbons (ACs), zeolites, MOFs) [9][10][11] , and ionic liquid adsorption.…”

Development and application of a rapid sampling technique for identification and quantification of compounds in high temperature process gas streams produced from biomass gasification and pyrolysis

“…This avoids the previous complications of caked particulate deposits and corrosive liquids. Results indicated that greater than 99.5 % HCl was removed with an additional 94 % removal of SO 2 [219]. Optimal efficiency for scalable designs is contingent upon further experimentation and a better understanding of other chemical reactions complicating the process [220].…”
