Sulphuric Acid Tanks

Sulphuric acid (H2SO4) is an odourless, semi-oily liquid that ranges in appearance from clear to yellow depending upon solution purity, where solutions are colourless.  It is a diprotic, (ie it can give off two hydrogen atoms on dissociation), strong mineral acid that is considered “weighty” due to its high density. Chemical solutions of sulphuric acid are very reactive and hazardous. These factors must be considered whenever handling and storing.

What is Sulphuric Acid used for?

Sulphuric acid is oily with a viscosity greater than water and as the temperatures increase, viscosity decreases. This viscosity is due to the internal molecular structure with a three-dimensional orientation and increased hydrogen bonding

It is commonly characterized as a “heavy” chemical solution because of its high density. This depends upon how concentrated the solution is and can vary between 1.07 to 1.84 g/cm3, (where water = 1.0 g/cm3). This makes sulphuric acid almost twice as heavy as water when occupying the same volume.

Sulphuric acid is a mineral acid with sulphur as its parent atom. (An organic acid is carbon-based.) It can be produced by dissolving sulphur trioxide gas in water.

Sulphuric acid is capable of dangerous reactions and is hazardous to human health. It is a strong acid due to the high dissociation constant of the first hydrogen released in reactions. A 98%, concentrated solution of sulphuric acid has a pH of about 0.1.

Sulphuric acid is a potent oxidizer capable of oxidizing certain chemicals and materials, such as some metals. When you add it to water there can be a violent reaction and a great quantity of heat is given off. This means that tanks for storing or mixing sulphuric acid with water must be able to withstand this heat.

How do I store sulphuric acid in tanks?

  • High-density polyethene (HDPE) tanks will withstand the heat.
  • Specific gravity ratings of 1.9 or higher are recommended to cope with the weight
  • Non-reactive materials like high- quality plastics
  • Bunded Sulphuric Acid Tanks to contain any leaks or spillage
  • The maximum service temperature of HDPE tanks peaks around 54 C (130 F).
  • Stringent engineering controls are required if plastic tanks are used and it is recommended that only pre-diluted sulphuric acid should be stored in plastic tanks
  • UV stabilizers or insulation need to be present if the tanks are outside to prevent degradation.

Enduramaxx Bunded Sulphuric Acid Tanks comply with all these requirements.
