Desulfurization

Sulfur removal is an important component of lead–acid battery recycling. Sulfuric acid from the battery is usually neutralized with soda ash (Na 2 CO 3) or with caustic (NaOH), treated to remove heavy metals and discharged to the public sewer system in accordance with local, state and federal regulations.When there is a lead recycling plant close to a battery manufacturing …

The principle of desulphurization and purification for …

The most basic purification principle is to apply wet dust removal, water film desulfurization and dust removal, impact water bath desulfurization and dedusting and other technical principles to the desulfurization dust collector''s technology and equipment. It has a good effect on the waste gas pollution of some industrial factories.

Dry Flue Gas Desulfurisation Technology

Dry FGD technology. There are various dry FGD technologies including LSD, spray dryer absorption, furnace sorbent injection, and circulating fluidized bed. Since the principle of most dry FGD processes (the SO 2 contained in flue gas mixes and reacts with lime slurry in an absorber) is almost the same, so LSD as one of the most representative ...

Working Principle Of FRP Desulfurization

2018-11-6 · Working principle of FRP desulfurization dust collector Desulfurization is a technology to control sulfur dioxide emissions. The dust collector can not only remove sulfur dioxide from flue gas, but also produce high value-added ammonium sulfate fertilizer products.

Desulfuration

Thermal treatment of thiiranes generally provides alkenes by desulfuration, and such a process has been employed in the synthesis of heterocyclic compounds.The reaction of phenylthiazole 15 in methanol at 50 °C provided (aryl)(amino)methylidene indolone 17, which was considered to involve a spiro thiirane intermediate 16 followed by thermal desulfuration (Scheme 5). 6 The …

Desulfurization

Very rapid desulfurization of thiiranes by a bimetallic complex was reported late in 1995. Bergman and co-workers found that Cp 2 Zr(μ- N-t -Bu)IrCp*, where Cp is cyclopentadienyl and Cp* is pentamethylcyclopentadienyl, desulfurizes thiiranes via a bridging sulfido complex 121, for which a crystal structure was obtained <1995JA10041> .

Desulphurisation

6.11.4.4 Process description of dry desulfurization. Dry desulfurization is precision desulfurization. The equipment''s fundamental principle of dry desulfurization is oxidizing the H 2 S to sulfur or sulfur oxides, which can be described as a dry oxidation process. After the concentration of H 2 S is desulfurized to <150 mg/m 3 by wet ...

What is the working principle of desulfurization and …

The working principle of desulfurization and denitrification is to reduce the generated NOX to N2 to remove NOX in the flue gas. According to the treatment process, it can be divided into wet denitrification and dry denitrification. mainly includes: acid absorption method, alkali absorption method, selective catalytic reduction method, non ...
