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.

However, this classification was based solely on solubility, while neglecting important parameters such as selectivity (Holbrey et al. 2008). Table 1, on the other hand, summarizes IL extractions focusing on selectivity. Imidazolium and ...

What is Desulfurization? - Definition from Corrosionpedia

Desulfurization is the removal of sulfur or sulfur compounds (as from coal or flue gas), mostly from fuels. The most commonly required desulfurization process is in natural gas, but it is also required for flue gas, coal and oil. Sulfur in crude oil, natural gas, process gas and natural gas liquids (LNG) may take many forms, including hydrogen ...
