Question

What are the advantages and disadvantages of the contact process?

Answer 1

Advantage :-

There are little or no waste by-products produced by this process. It is also the most economic way to get rid of sulfurous waste gases. 

Disadvantages:-

This process produces an acid with low concentration instead of the high concentrations that the Contact Process yields.

Answer 2

Major industrial process used to make sulphuric acid, by oxidizing sulphur dioxide in the presence of a solid catalyst and absorbing the resulting sulphur trioxide in water.

Advantage and disadvantage of contact process are

• Larger amount pf sulphuric acid is manufactured.
• High concentration of sulphuric acid is obtained as compared to all other process
• There are little or no waste by-products produced by this process.
• It is also the most economic way to get rid of sulfurous waste gases.
• The biggest problem is that the catalyst can be poisoned if the sulfur dioxide is not fairly pure.

Hence, this was all about the contact process
