Applications
What are the applications for Sulphuric Acid?
Sulphuric Acid is a versatile chemical with a wide range of applications across various industries.
Here are some of its primary uses:
Wastewater Treatment
Sulphuric Acid is commonly used in wastewater treatment processes for pH adjustment and to precipitate heavy metals. It helps in neutralising alkaline waste streams and enables the removal of metals, ensuring the treated water meets environmental standards for discharge or reuse.
Mining
Used in Mining to dissolve metals and minerals from ores effectively. Used in metal processing, Sulfuric acid is used in a mixture for what is known as “steel pickling”, which is a surface treatment process that is used to remove any rust or carbon impurities to finish the metal and is one of the final and most important stages of metal processing.
FAQs
Frequently Asked Questions
Got a question about storing or dosing Sulphuric Acid? Here’s what our customers ask most — from best-practice storage to safe handling and what to avoid mixing it with.
What is the best way to store Sulphuric Acid?
Sulphuric Acid is a highly reactive and corrosive chemical that requires special handling and storage. It is important that it is stored within a container that is resistant to corrosive chemicals. Sulphuric Acid is also extremely heavy and will test the integrity of any tank. This means the tank or container needs to be built for the purpose of holding Sulphuric Acid. It is very important to store Sulphuric Acid in a well-ventilated environment
Best practices for storing Sulphuric Acid
Store Sulphuric Acid in a cool, dry, and well-ventilated area away from direct sunlight.
Use containers made of compatible materials, such as our 7080 grade octene 2SG to store Sulphuric Acid. Never store in metal containers. It will attack metal resulting in a spill.
Store Sulphuric Acid separately from other chemicals, particularly bases, which can react with it and cause dangerous reactions.
Secondary containment is an absolute necessity. Make sure to surround the primary storage container to collect any spillage of Sulphuric Acid.
Ensure that Sulphuric Acid containers are tightly sealed and labelled with the proper hazard warnings.
Regularly inspect and check your tank for any signs of damage or wear that may occur and get them repaired immediately.
What not to store with Sulphuric Acid
Other alkaline-based chemicals.
Water. E.g. if Sulphuric Acid contacts water, it creates a toxic Sulfuric Acid aerosol fume and creates a risk of a potential explosion.
Sulphuric Acid can create a highly flammable Hydrogen gas if it is spilled on metals.
Depending on the concentration of Sulphuric Acid it may be corrosive to stainless steel. This should be reviewed on a case-by-case basis.
Chemical Storage & Handling
When it comes to the storage and handling of Sulphuric Acid it is important that it is handled safely, and that everyone on-site is kept safe. Here are a few guidelines to follow to keep your workplace safe:
Store the chemical in its own designated area, away from other chemicals and direct sunlight. If Sulphuric Acid is heated it may produce poisonous and/or corrosive fumes.
With any type of corrosive chemical using the appropriate personal protective equipment (PPE) such as gloves, goggles and face shield is a must, Sulphuric Acid is no different.
Avoid inhaling Sulphuric Acid fumes or mist, which can cause respiratory irritation and other health problems.
Always handle Sulphuric Acid with care and avoid splashing or spilling it.
Do not mix Sulphuric Acid with any other chemicals or substances without first consulting a qualified professional.
When mixing or blending chemicals with Sulphuric Acid, an exothermic reaction may occur, and the heat of the chemical can cause damage if not properly addressed.
