Flue-gas desulfurization - Wikipedia

Depending on the application, the two most important are lime and sodium hydroxide (also known as caustic soda). Lime is typically used on large coal- or oil-fired boilers as found in power plants, as it is very much less expensive than caustic soda.

Flue-Gas Desulphurization - an overview | ScienceDirect Topics

Nicholas P. Cheremisinoff, in Clean Electricity Through Advanced Coal Technologies, 2012 2.5 Flue-Gas Desulfurization Material. Flue-gas desulfurization (FGD) material is a product of a process typically used for reducing SO 2 emissions from the exhaust gas system of a coal-fired boiler. The physical nature of these materials varies from a wet sludge to a dry, powdered material depending on

CN104941423A - Ammonia desulfurization and denitrification

Kefid 13:31:21. There are many desulphurization methods for coal fired boilers, but there are three kinds of commonly methods, pre-combustion desulfurization, desulphurization in the furnace and flue gas desulphurization, and the most widely used is desulfurization in the furnace. ZBG mainly adopts furnace desulphurization instead of flue gas desulfurization, because it is selected from the cost budget of the customer and combined with the design structure of the boiler …

A 10-MW horizonal scrubber (see Chapter 11, Section 2.12) on an old oil-fired boiler sometimes receives sulfuric acid mist at 50 ppm when oil at 2 percent sulfur is used. The efficiency of removal is typically 50 percent (Weir 1975), although the efficiency has been varied …

Apr 24, 2021 · The product after the desulfurization reaction is blown out from the separator in the form of dry powder. This kind of desulfurization technology uses limestone or slaked lime as a desulfurizing agent. It has a high desulfurization rate and desulfurization agent utilization rate, and has little impact on the environment.

Valmet Flue Gas Desulfurization for emissions control

Jul 01, 2013 · The measurements presented in this work were based on the possibility of using new desulfurizers — Sorbacal SP and Sorbacal H 90 for the desulfurization of fluid boilers by means of their blowing-in into a flue-gas stream before bag filters and hence ensuring the fulfillment of the stricter emission limits for sulfur dioxide with a fluid boiler burning brown coals with a capacity of ca 375 t/h of …
