    Hi Mr ARMOFI

    Thank you very much for you sheet for the Nitrogen calculation.

    I'm a student and I would like to know what kind of the book or reference you generally use to determinate elemental composition of oil trought correlation. (%C, %H, %S, %O2, %N2, %Metals (Ni, V, Fe)
    Generallay I used several correlation of Riazi.
    (Riazi, M. R. (2005). Characterization and Properties of Petroleum Fractions. West Conshohocken, Panjeshahi, M. H.).
    However this one have several errors and the critical thing I don't found well correlation to N2, O2 and Metals.
    So for this reason I need you help. Could you bring me some kind of information about the determination of this elemental composition. You sheet it's already program and I could see the correlation employed for the case of N2.

    Another addiotal question that I will like to know it is the table of regulation of elemetal composition to be transport a oil.
    What kind of request or law it is necessary to supply for trasport a oil (e.x. %S, %N2, etc)

    Finally my mail is: jpl860@gmail.com

    Thank so much

    Hi,

    As far as using of Nitrogen for purging concerned, it depends on the removable of flammable gases inside the pipeline/tank/conduits etc (confined vessel). Particularly , this means Oxygen to a level of 10-12% desirable, the LFL of the content. The level of purging by N2 is dictated by the Client here.(what % oxygen removal required).

    Other question I am unable to understand & I think I am not an expert in it. If it is regarding selection of material for oil/liquid transportation, we follow the regulation list 49 CFR Part 192, AppxB. or the selection of materials as per ASME 31.4 / 31.8 or AISI/SAE Classification of metal. Obviously these are API 5L pipes of different schedule & grades.
