FLUE GAS DESULFURIZATION - Emerson Electric

What is Flue Gas Desulfurization (FGD)? FGD is a set of technologies used to remove Sulfur Dioxide (SO2) from exhaust flue gases in coal, oil-fired, and waste- to-energy power stations. SO2 is a pollutant/irritant in air and a major contributor in the creation of acid rain. SO2 emissions are subject to strict environmental protection regulations.

Recent advances in flue gas desulfurization

01.12.2019  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. On the other hand, the regenerable processes release

15.03.2021  The study of flue gas desulfurization is of great significance to environmental protection. With the principle that sulfur dioxide (SO 2) can be liquefied with the cooling of flue gas and further be removed with gas-liquid separation, a cryogenic desulfurization process was designed based on Aspen plus. The steady state process was simulated by using appropriate property methods included in
