Properties of Sulfuric Acid

　　Sulfuric acid, with the chemical formula H2SO4, is soluble in water and is an extremely corrosive chemical, making it very dangerous for those in direct contact with it.

Chemical Properties

　　Industrial sulfuric acid is a strong acid with strong corrosive and oxidizing properties. It is capable of reacting with many metals, non-metals and their compounds to produce the corresponding sulfates or gases such as sulfur dioxide. At the same time, industrial sulfuric acid is also dehydrating and water-absorbent, capable of dehydrating and carbonizing organic materials, as well as absorbing moisture from the air.

Physical Properties

　　Industrial sulfuric acid is a colorless or slightly yellow liquid with a pungent odor. It is denser than water, has a higher boiling point and is not volatile. The purity of industrial sulfuric acid is generally low, containing impurities and water.

　　Sulfuric acid is widely used in various industries and is vital for chemical production. Sulfuric acid is also used in the industrial production of metals, among other industries and manufacturing.

What are the applications of sulfuric acid in industry?

　　Sulfuric acid is one of the most important compounds in the chemical industry. It is used in the manufacture of hundreds of compounds required in almost all industries. The global production of sulfuric acid is about 180 million tons per year, with the United States alone producing about 40 million tons, and Europe and Russia producing about 19 million tons and 9 million tons, respectively. Some of the applications of sulfuric acid in industry are as follows:

• Chemical production: Sulfuric acid has a wide range of applications in chemical production. It is used in the manufacture of dyes, pigments, pesticides and other chemical products. Besides, sulfuric acid is also used in the production of rubber, plastic and other polymer materials.
• Fertilizer production: sulfuric acid can be used to manufacture phosphate fertilizer, which is obtained by mixing sulfuric acid with crushed phosphate rock and further processing.
• Desalination: Desalination is the process of removing salt and minerals from brine, but often includes the removal of salt and minerals from any substance. In the case of brine, sulfuric acid is used to regulate the pH of seawater.
• Dye Production: Particularly in the production of acid dyes, sulfuric acid is used to set the color of the dye, and dyes produced using sulfuric acid or other forms of acid often have unique properties and advantages over other types of dyes.
• Phosphoric Acid Manufacturing: Phosphoric acid is commercially produced by wet, thermal or dry kiln processes. About 80% of the world's phosphoric acid is obtained by the wet process.
• Pharmaceutical and chemical production: Sulfuric acid is used in the manufacture of drugs, explosives, pigments, detergents, storage batteries, etc. and is an important industrial raw material.
• Paper Industry: Sulfuric acid is one of the components used in the manufacture of paper and pulp to generate chlorine dioxide, a powerful bleaching agent and facilitator of pH correction.
• Sugar bleaching: Liquid sulfur dioxide (a precursor to sulfuric acid) is added to ground white sugar and then evaporated to brighten its color.

Sulfuric Acid Industrial Pump Selection

　　Pure sulfuric acid is intensely corrosive to any substance it comes into contact with, so you need to choose wisely when selecting the right sulfuric acid chemical pump.

　　Before deciding which pump to choose for handling sulfuric acid liquids, you should be aware of the properties of sulfuric acid that affect the different components of the pump. You should also consider different aspects to determine the best sulfuric acid pump for your particular application. These aspects include, but are not limited to, the concentration of the acid, the temperature of the liquid, the specific gravity, and the materials that make up the pump. Depending on the concentration and temperature, the chemical sulfuric acid may also be heavy.

Here are some factors to consider:

　　Sulfuric acid is divided into dilute sulfuric acid and concentrated sulfuric acid, generally dilute sulfuric acid I am in the choice of PRPP material plastic pump can be, if concentrated sulfuric acid you need to choose PVDF material plastic pump.

　　According to the flow and head to choose the type of pump. This is based on their actual use of the calculated values, manufacturers or engineers will be based on this parameter to choose the pump model.

Meibao sulfuric acid pumps can be divided into the following categories:

• For conveying lifting process: Sulfuric acid self-priming pumps;.
• For unloading process: Sulfuric acid magnetic pumps.
• For precise metering process: Sulfuric acid metering pumps.
• If the sulfuric acid contains a small amount of impurities: Sulfuric acid pneumatic diaphragm pump.

　　The high concentration and temperature of the chemical sulfuric acid, either alone or together, may make the above pumps unsuitable. It is strongly recommended that you contact your local distributor or contact Meibao Pumps directly to review your application before ordering a pump, regardless of temperature or concentration.
