Sir,

Any one please guided me to how to check the static electricity generation in petroleum product terminals and how to get the electrical conductivity values for diesel and MS.

Consider this resource :

For resistivity you should be able to measure them or check the MSDS

Hope this helps

Some data can be found in http://www.cheresour...ity-generation/. Can you please clarify MS? Concerning diesel oil following is noted.
1. http://www.astm.org/Standards/D975.htm : 7 grades of diesel reported, conductivity is measured for each grade. Expect conductivity variation from grade to grade.
2. Sulfur content is expected to have an influence on conductivity. Trend seems to be for ultra low sulfur diesel (ULSD) of 15 ppm S. See http://www.envirofue...etin-070307.pdf. The conductivity diagram in the last page of referred bulletin / link shows (as examples): untreated high sulfur diesel 226 pS/m, untreated ULSD 10 pS/m (as proposed minimum), treated ULSD (with additives) 261 or 464 pS/m.
3. Googling "electrical conductivity diesel", you can see under the finding "Fuels:Canada" electrical conductivity (min) 25 pS/m, 25 pS/m,.... Yet I cannot locate it in the text (part of it is presented, article is not free) and do not know what grade concerns.
4. You had better measure electrical conductivity experimentally, at least few measurements to see present range; then think of the future status, too.
