I would like to know about sulphur dioxide cylinder specifications ,storage tank specifications. I could not locate information on net.

Hi,
This has to be designed to your specific requirement.
The data for such design would be pressure at which you want to store?
You will hvae to Design the Pressure vessel as per ASME Section VIII
Thanks & Regards,

Sulphur dioxide cylinder is a used item.Details must be available like chlorine with some senior members.I was thinking of extrapolating information.
I can understand issue about storage tank.Installation where I saw this had a storage tank pressure about 4 kg/cm2.So far information which I am able to get is as follows.
21.1 degree centigrade kg/cm2
kpa 237 2.37
psig
liquefaction kpa 388 3.88 32.2 degree centigrade 56.3
3.843003413 kg/cm2
Design Temperature and Pressure
The design temperature must take into account the typical ambient temperatures since this affects the vapour pressure of liquid SO2. A typical maximum operating temperature is 50°C. The mechanical design temperature can be conservative set at 100°C.
The design pressure must be set higher than the vapour pressure at the maximum operating temperature. A typical design temperature for a storage vessel is 1448 kPa(g) (210 psig). Relief valves should be set at 1379 kPa(g) (200 psig), which is 5% lower than the design pressure.
Materials of Construction
All materials should conform the ASME/ASTM standards. Typically, ASTM A516 Gr. 70 carbon steel will be used for all pressure containing parts. When cold product or ambient temperatures are involved, all material must be impacted tested using Charpy 'V' notch specimens at -46°C (-50°F). No specimen must be less than 15 ft. lbs.
In addition to impact testing, all material shall be normalized.
Corrosion Allowance
Even though anhydrous liquid SO2 is not corrosive to carbon steel, any moisture entering the tank when in contact with liquid SO2 will be corrosive. A typical corrosion allowance will be 3 mm (1/8").
Based on this I would like to know shell thickness and dishend thickness.

Dear Mr. S.K.Deshpande,
Thanks for sharing the detail specifications.
I would like to try to workout the shell and dish end thickness.
I may have to refer some books, hence shall give a try once I get some time.
However I am not confident of arriving at the correct thicknesses as this is specifically a Designers Job. That is the reason I shall not share on this forum, if you can let me know your e-mail id I can send you the calculation sheet in excel file.
in case you desire pl revert back to me at
Thanks & Regards,

There is a practice of filling sulphur di oxide liquified in tonners/cylinders normally used for liquid cylinders . Being corrosive gas additional safety is alwayas better.Many of the filler are using old /used cylinders for the purpose. liquid chlorine design pressure is higher 19.9g/cm2.Bases on vapor pressure of Sulphur di oxide desigin pressure can be reduced.But still i suggest you to use chlorine tonner design for safety reasons. You can approach the tonner manufacturer INDIAN SUGAR AND GENERAL ENGG COMPANY YAMUNAGAR -HARYANA,Concerned person contact no is 09996048709.
DETAIL DESIGN DETAIL OF CHLORINE TONNER/CYLINER IS ATTACHED.
CYLINDER/TONNER IS THE NOMANCLATURE BESED ON ONE TON QUANTITY IN IT. ANY VESSEL LESS THAN 1000 LITRES IS CALLED TONNER/ CYLINDER

Thanks for sharing information.I have used sulphur dioxide cylinders in the past.Their ratings must be lower than chlorine cylinders which I do not know at this juncture.Have a nice day.
