Sulphuric acid plant cost optimization

[devenbaser]

This is regarding the previous point raised by me , about treating the SO2 that leaves the reactor with a solution 

1)this way we can save on the two additional reactors 

2)have an increased SO2 conversion rate in terms of time of the process

3)environmentally better

4)ideal for small plants , so that there can be some amount of money saved of the initial capital

we need to add a scrubber that are easily available, basically consisting of line slurries, it can be used in the form of sprays or packed bed column.

the link below gives the feasibility of a scrubber, and the attached file gives the costing

it is important to note that with a scrubber we may save on that additional time we spend on reacting the additional 20% SO2, thus making the plant a little more efficient .

Could you use that data to make your case?

[Anish Acharya]

is reaction of hydrogen peroxide with unreacted SO2 feasible ? we can react the unreacted SO2 with it and use even that to produce sulphuric acid.

Hydrogen Peroxide is unstable and decomposes easily to give water and oxygen as supported by thermodynamic data. The aforementioned reaction needs to be carried out at very low temperatures for good conversion. This probably makes it inefficient for industrial purposes to manufacture Sulphuric Acid.
