Reagents for Desulphurization of Hot Metal – IspatGuru
Lime is the cheapest hot metal desulphurization reagent which is being used. However, it has a lower effectiveness. It also produces large quantity of slag and, since iron losses are directly proportional to the generation of slag, this adversely affects the cost.

Analysis of limestone for flue gas desulfurization in a power
What is flue gas desulfurization? A flue gas desulfurization (FGD) processing unit, commonly referred to as a scrubber, removes sulfur dioxide (SO 2) from the exhaust flue gases in power plants that burn coal; airborne SO 2 oxidizes within airborne water droplets to form sulfuric acid (H 2 SO 4) forming “acid rain”.

Desulfurization
Many of the agents responsible for neutralizing H2S can separate the sulfur from its compounds. However, research demonstrates that an iron oxide sold sponge — i.e. wood shavings infused with iron, or ferric, oxide — is effective in hydrogen desulfurization by first absorbing the H2S, and then converting ferric oxide into ferric sulfide.

The Flue Gas Desulfurization Process: Staying ELG-Compliant
The Flue-Gas Desulfurization (FGD) process utilizes a set of technologies to remove sulfur dioxide (SO 2) from the flue gas emissions of coal-fired power plants.FGD systems were developed as a response to the exhaust – flue gases – from fossil fuel-burning plants, principally coal-burning, that posed both an environmental and human health hazard.

The slaked lime is produced by hydrating raw lime to form calcium hydroxide. This slaked lime is atomized and absorbs the SO 2 in the flue gas. The SO 2 reacts with the slurry droplets as they dry to form equimolar amounts of calcium sulfite and calcium sulfate. The water in the lime slurry improves SO 2 absorption by humidifying the gas.

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.
