Flue-gas desulfurization

A new, emerging flue gas desulfurization technology has been described by the IAEA. It is a radiation technology where an intense beam of electrons is fired into the flue gas at the same time as ammonia is added to the gas. The Chendu power plant in China started up such a flue gas desulfurization unit on a 100 MW scale in 1998.

a combination of physicochemical processes that promote the removal of sulfur from molten metal (cast iron, steel). It consists in converting the sulfur dissolved in the metal to sulfides that are either insoluble or poorly soluble in the liquid metal bath (for example, MnS, MgS, CaS, and Na 2 S). Examples of desulfurizers are lime, sodium carbonate, and metallic magnesium.

Chemistry

Desulfurization - make hydrocarbons from thioacetals and hydrogen with Raney nickel. Imines - make imines (C=N-R) from aldehyde or ketone and primary amine. Wolff-Kishner Reaction - reduce C=O to CH 2 in aldehyde or ketone with hydrazine (H 2 NNH 2) and base, via hydrazone (C=NNH 2)

How to Restore Sulfated Batteries | Battery Chargers

Sulfation (sul-fay-shun), the number one cause of early battery failures, can be safely reversed, using high frequency electronic pulses. Unlike other pulse type battery chargers that claim this or similar sounding features, VDC''s BatteryMINDers® use a range of high frequencies. This ensures both old and newly formed sulfation will be safely dissolved in the shortest possible time.

The fluxes control the chemistry and sulfur and phosphorus capac- ity of the slag. The principle active ingredients from the fluxes are CaO (from burnt lime) and MgO (from dolomitic lime). The CaO component is used principally to control sulfur and phosphorous. The dolomitic lime is used to saturate the slag with MgO.
