MAI I HAVE SOME INFORMATION AS THIS IS MY FINAL YEAR PROJECT.
OR ANY PREVIOUS PROJECT RELATED THIS ONE?
I WANT TO DESIGN lpg STORAGE FACILITY ACCORDING TO nfpa 58 AND asme codes.

[AHMEDMUJTABA65]

MY FINAL YEAR PROJECT IS " DESIGNING OF LIQUID AND GAS FUEL STORAGE FACILITY"
I HAVE DESIGN LIQUID FUEL (FURNACE OIL) STORAGE FACILITY IN LAST 6 MONTHS WITH THE HELP OF API650 AND NFPA 30.
DESIGNING INCLUDES 2 TANKS WITH A SMALL CAPACITY OF 1000 m3 EASH, PUMPS (LOADING AND UNLOADING), WATER TANK AND FORM SYSTEM FOR FIRE FIGHTING AND THERE PUMPS. TANK INCLUDES HEATING COIL AS WELL FOR HEATING FURNACE OIL.

NOW I HAVE 2 MONTH REMAINING TO DESIGN GAS FUEL STORAGE FACILITY.
I HAVE SELECTED LPG.
5 HORIZONTAL BULLET TANK 220 m3 EASH CAPACITY.( CAN BE CHANGE). WHICH CAN BE FILLED UPTO 85 % ROUNDING UPTO 1000 m3.

it would be great if you provide help in calculation of capacity,LENGTH AND DIAMETER, TYPE OF HEAD, the number of nozzles and their sizes and other process parameters such as physical properties of the fluid stored (density, viscosity, vapor pressure @operating temperature) , operating pressure and temperature and design pressure (vacuum) and temperature.

Ahmad:

I have already advised you in my message service that our Forum members are not going to do your work for you. Why do you continue to ask for answers to your work assignment without you doing any work input? I advised you to use the SEARCH engine and look for the Vessel Volume workbook which answers most of your questions and gives you the ability to do your own calculations. Why haven’t you done so? You can find reference to it at: http://www.cheresour...ls/page__st__25

If you find the thread locked, ask for a copy of the specific workbook – but do the required leg work and put an effort into your assignment. Why haven’t you started on a vessel Data Sheet (Specification Sheet)? Why haven’t you generated your own PFD? Have you researched through Google, as I recommended? If you need a Data Sheet form, just ask for it (although you could SEARCH and find where I already uploaded it for students to use.

I also advised you where to go for FREE thermodynamic properties on the LPG compounds so that you can obtain all the information. Have you done that yet?

This is an easy, common sense type of project and you need to get started on doing your own organized work instead of depending on others for doing it for you. It isn’t going to happen that way.

I HAVE DOWNLOADED vessel volume workbook and will go through it.
as well as LPG thermodynamic properties

http://www.cheresour...19-lpg-terminal '> http://www.cheresour...19-lpg-terminal (updated today) may be useful in the specification of each bullet capacity, length, diameter, preliminary layout. Probably this student task is a preliminary basic design ending with some capital cost estimate? Time of two months seems rather short, but I assume a student team will work for it.
We usually accept 2:1 elipsoidal heads (yet other types are not excluded), each one having a total volume of half elipsoid. If R is the cylinder radius, volume of elipsoid is 4/3*π*α*β*γ (Perry, mensuration formulas, solids bounded by curved surfaces). In case of 2:1 elipsoidal, α=R, β=R/2, γ=R/2, so the half volume of the head is 1/6*π*R^3=1/48*π*D^3, D=2R (complies with Vessel Volume workbook).
Volume of hemispherical head is just half a sphere, that is 2/3*π*R^3=1/12*π*D^3.
As the work proceeds, questions on specific issues can be placed for trying a way out or giving suitable references. Good luck!

hi ahmad

Sorry to butt in without giving quantitative answers'.

As Art mentioned, you are requested to do the calculations yourself; you can ask for guidelines, sizing methods and probably even help in troubleshooting your spreasheets and calculation notes.

to quote you have said:
"it would be great if you provide help in calculation of capacity, LENGTH AND DIAMETER, TYPE OF HEAD, the number of nozzles and their sizes and other process parameters such as physical properties of the fluid stored (density, viscosity, vapor pressure @operating temperature) , operating pressure and temperature and design pressure (vacuum) and temperature."

you have asked for all numbers from the forum; then what will YOU do? Type it and bind it as a presentation?

Now, coming to your topic, it talks about liquid and gas fuel storage; is there any guidelines given by your professors as to the following:

what type of liquid fuel and what gas fuel? (why not diesel and propane or compressed natural gas? why furnace oil and LPG? (why you consider LPG as gas fuel; it is a gas fuel but stored as a liquid; so you handle it as liquid!
how they are delivered in? tankers, pipes, rail? if the delivewry is batch, what is the frequency of dleivery and size of delivery parcel? what is the need for storing at your selection point; who all will be receiving fuel from your storage; how much they receive and how it is metered? is it manned; how and any remote measuring?
what are the fire protection and environmental needs? what exactly are you "designing" - plot area, size of the tanks, layout, fire water lines, first aid fire protection systems and probably DCP delivery systems?

The above all can be answered, if you have made a basis of design document and if you have made one upload.
