    Storage Tank Roof Type

    I'm an engineer and studying about Storage tank in Oil & Gas field. However*
    as i searched on internet and got the picture (attachment) from youtube: ""
    but i could not find out the demonstrated sketch or image. Anyone can help me clear storage roof type.

    Thank you very much!

    Mr Linus*
    Thank you for your information*
    By the way* there are three storage tank roof type such as: Fixed* External & Internal roof*
    My inquiry about how to select proper tank roof type for:
    1) Refinery production: Gasoline* DO* FO* HGO* LCO* Kerosone* RFCC* CCR* reformate* isomerate....
    2) Chemical: methanol* Etanol* Glycol* PPD* Chemical injection system
    3) Condensate* Crude oil
    i wanna to hear from you*
    Thank you*

    Re: Storage Tank Roof Type

    Roof selection is decided largely by the content's propensity to form vapours* the losses due to the emissions* the costs for mitigation or recovery of the emissions and the environmental laws in place regarding the emissions.

    Fixed roof is generally the first choice for storage* however if any of the above prevail* then floating roofs are used.
    Fixed Roof Tanks are used to store materials with a true vapor pressure of less than 1.5 psia absolute.
    Floating Roof Tanks are preferred for storage of petroleum products with a true vapor pressure of 1.5 to 11 psia absolute. Internal floating roofs accord greater control over emissions and vapour recovery than External floating Roof.

    Medium flash point products as Crudes* Diesel* Kerosene*Naphtha* Reformate and the like are stored in external Floating Roofs. However if storage Volume is small* and thereby emissions are not a concern* Fixed Cone Roofs can be used for storage.

    Low Flash point products as ethanol* gasoline* Motor Spirit* Aviation Turbine Oil* Isomerate are stored in Internal Floating roof tanks.

    Glycol and Methanol could be stored in fixed roof vertical tanks. Horizontal tanks with domed ends could also be used for glycol.

    Re: Storage Tank Roof Type

    The sketch basically shows the different type of roofs to use. Does the tank have a roof--- Yes-----then it can be either a column supported or self supported roof. If it is self supported it can then be a Dome, Umbrella or Dished type.
