This has to be designed to your specific requirement. The data for such design would be the pressure at which you want to store. You will have to design the pressure vessel as per ASME Section VIII.

Sulfur Dioxide Cylinder Specifications
Sulfur dioxide cylinders are used items. Details must be available, similar to chlorine, with some senior members. I was thinking of extrapolating information.
I understand the issue about the storage tank. The installation where I saw this had a storage tank pressure of about 4 kg/cm². So far, the information I have been able to gather is as follows:
- 21.1 degrees centigrade: 237 kPa (2.37 kg/cm²)
- Liquefaction: 388 kPa (3.88 kg/cm²) at 32.2 degrees centigrade (56.3 psig)
Design Temperature and Pressure
The design temperature must consider typical ambient temperatures since this affects the vapor pressure of liquid SO₂. A typical maximum operating temperature is 50°C. The mechanical design temperature can be conservatively set at 100°C.
The design pressure must be set higher than the vapor pressure at the maximum operating temperature. A typical design pressure 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 to 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 materials must be impact 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 the shell thickness and dish end thickness.

There is a practice of filling sulfur dioxide liquefied in tonners/cylinders normally used for liquid cylinders. Being a corrosive gas, additional safety is always better. Many of the fillers are using old/used cylinders for the purpose. Liquid chlorine design pressure is higher at 19.9g/cm². Based on the vapor pressure of sulfur dioxide, design pressure can be reduced. However, I suggest using the chlorine tonner design for safety reasons. You can approach the tonner manufacturer, Indian Sugar and General Engineering Company in Yamunanagar, Haryana. The concerned person's contact number is [Phone Number Removed For Privacy Reasons].
Detailed Design Information
Detailed design information of the chlorine tonner/cylinder is attached. Cylinder/tonner is the nomenclature based on one-ton quantity in it. Any vessel less than 1000 liters is called a tonner/cylinder.

If this falls under Petroleum Products, then the API guidelines should be followed for designing. To the best of my knowledge, OISD provides only safety directives. The API code specifies the design requirements for pressure vessels.
