Sulfuric Acid Wet gas Sulfuric Acid (WSA) Go to Sulfuric acid. The WSA process is a wet gas catalytic process. The concentrated sulfuric acid is produced by condensation from a wet process gas. Drying of the process gas prior to treatment in a WSA plant, therefore, becomes superfluous, hence generation of wastewater and loss of sulfur are avoided.
sulfuric acid | Structure, Formula, Uses, & Facts .
acid jets provides additional cooling and cleaning Electrostatic Precipitators: Acid mist and remaining Weak Acid dust particles removed Pump Tank 3. The Production Process Historically, sulfuric acid production was based on the Lead Chamber Process, involving the oxidation of sulfur dioxide by nitric acid and nitrogen oxides in the presence of water.
Sulfuric Acid is made in two differnt ways. General. Sulfuric Acid can be made in two different processes. One is called Lead Chamber and the other is called Contact. The Lead Chamber Process is the older process, and is used to produce the acid used in fertilizer, which is a more dilute acid.
CONTACT PROCESS Sulfuric acid is one of the most important industrial chemicals Outline three uses of sulfuric acid in industry 1. The major use of sulfuric acid in Australia is in the manufacture of fertilizers such as ammonium sulfate and superphosphate. Superphosphate is produced by reacting sulfuric acid with rock phosphate.
Sulphuric acid is a very important chemical worldwide and over one million tonnes of sulphuric acid are made in the UK each year. The raw materials required to manufacture sulphuric acid …
Smelter acid will be more than 25% of world sulphuric acid production com- pared to some 18% in 1991. Table 2 Production of Sulphuric Acid in the Countries of the European Community Sulphuric acid is produced in all the countries of Europe with the major producers being Germany, Spain, France, Belgium and Italy.
The SO 2 in the gas is made into sulfuric acid by (i) catalytically oxidizing it to SO 3 then (ii) reacting this SO 3 with the H 2 O(ℓ) component of strong sulfuric acid. Sulfuric acid is used for making fertilizer, leaching metal ores, refining petroleum, and manufacturing a myriad of products.
Acid must be cooled less than 45 0C. Single Contact Double Absorption (SCDA) Process: In this process of sulfuric acid production gases after 4th pass are passed to cooler and then economizer and their temperature is maintained at about 200 oC for absorption of gases in strong acid.
Sulfuric acid has a wide range of applications including domestic acidic drain cleaner, electrolyte in lead-acid batteries and various cleaning agents. It is also a central substance in the chemical industry. It is widely produced by contact process. Production of Sulfuric Acid by Contact Process:
• large plants can produce 1.3 tons in excess per metric ton of. acid. •in some countries, energy from sulfuric acid plants is used in. homes and offices saving ~ 35 700 tons of fuel oil per day!
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.
Sulfuric acid is type of common used inorganic chemicals. It's widely used as raw materials for fertilizers, medicines, metal pickling, explosives production, dye production and etc. KAPSOM provides well-proven solutions to modern sulfuric acid plant.

There are three basic types of sulphuric acid plants: Sulphur Burning Acid Regeneration Metallurgical. Acid regeneration plants include plants that decompose spent sulphuric acid into SO 2 and H 2O to be regenerated in to fresh acid and plants that take waste sulphur gases (H 2S, CS 2) to produce acid.
Acid mist and remaining Weak Acid dust particles removed Pump Tank 3.
