Recent advances in flue gas desulfurization gypsum

2019-12-1  The flue gas desulfurization (FGD) processes can be separated into two main categories: once-through and regenerable processes, depending on how the sorbent is treated after SO 2 adsorption (Srivastava and Jozewicz, 2001).Once-through, or non-regenerable, processes utilize the sorbent as a beneficial by-product or dispose of it as waste.get price

Flue Gas Desulfurisation an overview ScienceDirect Topics

Flue gas desulfurization (FGD) is a very common method for gas claning adopted in a gas processing plant. In this process, the flue gas with acid vapors is scrubbed to remove it as a by-product. Most of the FGD processes use alkali to scrub the flue gas. Many designers of FGD adopt the limestone gypsum process.get price
