The sulphuric acid dilution system can be manually started by the operator or can be automatically activated by the optional control system. For very strong sulphuric acid dilution ( 30%, 50%, or 70%), the system mixes the strong acid and water in the sulphuric acid static mixer using high turbulence created with a specialized system design.
Jun 03, 2015· Originally, the simple contacttype exhaust sulfuric equipment, such as boiler combustion gases, it was a process for producing sulfuric acid from a very thin SO2 concentration of the gas, at present, it and the high density SO2 from metallurgical type roasting furnace gas, H2S from oil refining, coke oven gas purification H2S, sulfur sludge ...
Nov 03, 2015· The production of sulfuric acid is an important process, because sulfuric acid is one of the chemicals most commonly used. Two main methods for the production of sulfuric acid are the double contact process and the WSA process. Both processes occur, for example, in the chemical, petrochemical and mining sector.
Phosphorous fertilizer component 4 To isolate phosphorus from phosphate rock, it is treated with sulfuric acid, producing phosphoric acid. Some of this material is reacted further with sulfuric acid and nitric acid to produce a triple superphosphate, an excellent source of phosphorous in solid form.

Manufacture of Sulfuric Acid The Contact Process. Sulfuric acid is made using the contact process. Sulfuric acid has many uses in industry. The amount of sulfuric acid which a country uses in one year can be a measure of that country's economic development (how modern or wealthy it is). Raw Materials to Make Sulfuric acid.
If sulfur trioxide is combined with water to produce sulfuric acid vapors, an additional condensation step is required to convert the vapors into liquid sulfuric acid. Instead of dissolving it in water, sulfur trioxide is combined with sulfuric acid to form oleum, which is also known as fuming sulfuric acid or disulfuric acid.
Sulfuric acid must be used in combination with water. The sulfuric acid creates a chemical reaction with the alkaline Ammonia which neutralizes the Ammonia and effectively scrubs the air stream. When the Ammonia is neutralized in this fashion a salt by product (ammonium sulfate) is produced.
Aug 14, 2012· New large sulphuric acid production plants now–a–days utilize double conversion double absorption (DCDA) process. DCDA process can realize above 99% conversion efficiency. The manufacturing process for sulphuric acid by the single absorption process and DCDA process are shown in Figure 7–9 and Figure 7–10 respectively.
Job Description: The Sulfuric Acid Operator is responsible for performing duties to obtain test samples, conduct laboratory analysis of samples, and monitor equipment operation involving boiler feed water, boiler water, cooling tower, and Turbo generator condensate return. This is an hourly position and will report to the Sulfuric Acid Shift Supervisor.
hydrochloric acid with a capacity of 2,800 tons per annum. Hydrochloric acid is used in the production of pharmaceuticals, dyes, pigments and leather. The country`s requirement of hydrochloric acid is met through import. The present (2012) demand for hydrochloric acid is estimated at 1,637 tons.
Process efficiency is key to the successful production of sulphuric acid. Increasingly, manufacturers look to Alfa Laval for process expertise, reliable corrosionresistant equipment with outstanding heat transfer efficiency, and broad services to support optimal performance. As a longtime partner to the industry,...
Sulfuric acid is a very important commodity chemical, and indeed, a nation's sulfuric acid production is a good indicator of its industrial strength. The major use (60% of total production worldwide) for sulfuric acid is in the "wet method" for the production of phosphoric acid, used for manufacture of phosphate fertilizers as well as trisodium ...
Solubility in weak sulphuric acid is typical for most spent acid from refinery and nitration processes. If the dust and ash solids are not soluble in weak acid, electrostatic mist precipitators are required. The SO2 bearing gas is then dried by contact with 93 to 96% H2SO4 in a packed bed acid tower or drying tower.
Aug 06, 2019· A strong proton donor is needed to make the carboxylic acid act as if it were, of itself, a good proton source. Sulfuric acid in esterification accomplishes the task by injecting a proton into the carboxylic acid structure through the reaction H 2 SO 4 +RCOOH→HSO 4+RC + (OH) 2.
