H2SO4 dilution
H2SO4 dilution
(OP)
how do we dilute concentrated H2SO4 (98%)in industry? since a lot of heat will be release if we add water to acid.

RE: H2SO4 dilution
For higher acid concentrations several dilution systems may be required.
But remember that the system should be provided with proper interlocks and needs engineering calculations followed with strict safety evaluations to ensure a safe operation.

Of course I am skipping (essential) details like Material of construction, concentration analysis etc, but hope you get the picture.
RE: H2SO4 dilution
We plan on injecting the 10% H2SO4 into existing pump suction housings that are cast stainless 316. It is essential that we not exceed 104 degF at 10% H2SO4, else the acid will be too aggressive. The water will be 80 degF, and the 98% H2SO4 may be as high as 100 degF.
RE: H2SO4 dilution
Dear,
Before dilute the H2SO4 we can add dry soda ash to decrease it concentration.the soda ash is cheap and can suppress the acid reactivity. Then you can dose the Acid Amount by 3% NaoH solution until neutralizing is completed.

There You can find a commercial unit designd
for sulphuric acid dilution.
RE: H2SO4 dilution
Among many alternative ways to find heat of dilution data, you may try and locate a book titled " Sulphur, Sulphur Di Oxide and Sulphuric Acid " written by UHF Sander, H Fischer, U Rothe and R Kola. This was published by British Sulphur Corporation in 1984 and had ISBN 0-902777-64-5 as reference.
I have the book and from this I can tell you that the heat liberated will be approx 750 kJ/kg of 100% H2SO4.
Good luck!
