Designing a 200-km Petroleum Pipeline

I am not expert of field but-

I think you don't need any pump If you are climbing height h meters and coming down by h meters at other side of hill.Siphon should work.

Only thing you need to do is just put two valves at both side of hill,close both the valves,somehow fill the pipe once and open both valves,

Just my own thoughts. need to be validated by experts

" ......... close both the valves,somehow fill the pipe"

Somehow do you will fill the pipe without a pump?

Thanks for putting point.

As I wrote before too, that I am not an expert and never been in the filed under discussion. But Just want to know, if we fill that bow once somehow do we need pump anymore? provided valves at both the ends are operated in write sequence at the time of shut off and on of pipeline.

When I said somehow mean a temporary pump.

Please note:-I am not ruling out the role of pump that has to be used for horizontal flow of oil.

Forget about a siphon

If this is for homework say it and you may get some ideas from CR4.

If this is for real - wow you have problems.

There are 200km and longer petroleum pipelines in SA and all over the world that was designed properly.

You must first obtain and study the related law of your country:-

The environment protection law , river crossings, health and safety , petroleum regulator laws, pollution and much much more. This alone will keep you occupied for a long time.

I am surprised in more than one way.

How can some body give you such a project if you have no knowledge about similar works?

How can you involve in such a project without making a deep research on the subject, not only on a forum as CR4?

How can you base your work on a forum recommendation?

As you were told forget the 1st suggestion the friction losses on 100 km are so high that you cannot get such a functioning siphon.

Follow the suggestions already given look at the rheological properties of the fluid to be used, get a good knowledge about pumps or ask a GOOD consultant for support.

Your problem is a non trivial economic optimisation one considering ALL aspects as well investment as cost of use, it is a problem of optimal cost of ownership with a ROI time aso!

It is not on a forum that you get the necessary support but from a person who already was confronted to similar problems.

Good luck and consider the difficulty of such a project

I hope the pipe stays where it is and the oil goes hill up.

Forget siphoning and other tricks, some serious pumps and temperature maintenance are needed as you will need to keep the oils viscosity as low as possible.

Sometimes it is wiser to go round this kind of obstacles as there might be a good reason why the region is not cultivated. (unstable slopes just being the easiest to overcome)

Find a good route first, then get an approval of all parties involved and the building permit signed off.

Then you can find a balance between installation and operating cost, a wide pipe with a lot of insulation and heat tracing allowing a slow flow will cost the most to install but lowers operation costs. A small pipe costs way less to install but a lot more to operate as you will have to maintain a lot of pumps along the traject.

What is your role?

We have a problem here!!!!

First we have fools, or perhaps, just ignorant, lazy slobs who want someone else to do their homework/work, for free and then there are many of us who can't resist offering advice while freely admitting that:

"I am not an expert and never been in the filed under discussion. But"

Why can't we just NOT RESPOND to the "I wants"

What's your Reynolds number today?

I'm more in trouble with all those stupid questions on cars.

Hello,

I hope this a University work.

If you are counting in km this means you are from my world of units/area.

If you are a engineer which is doing this project than we are in trouble.

Check API 610 and god bless the investor!

I'm very grateful that my parents didn't name me "Guest".

There are far too many people in this world named "Guest". They all fall into two groups:

1) Please do my homework for me.

2) I'm in charge of a big project where a mistake means millions of dollars (or whatever) will be lost, environment damaged and people killed. Since I never did homework and I don't have a clue. Would you please do my engineering for me.

I am worried about the project, where project is being led (I suppose) by person like you.. totally ignorent about the project.

No wonder, you have posted the question as guest. Otherwise, you would not be at that position.

Ask me for a quote on designing a 200-km Pipeline and forget the hill and the km.

Care shall be taken about the difference between the NPHSA and the NPSHR of the selected pump. Infact, the maximum allowable pressure drop in the discharge piping should be lower than NPSHA-NPSHR to avoid potential cavitation.

Forget the siphon phenomena because the pressure drope in the piping will changes cross the time while your oil contaminants such as "paraffines heavy HC" still flowing with your oil. If any, suitable paraffines slovent shall be used.

I suggest to do this calculation:

- Use a multistage centrifugal pump that's suitable until the 1600 m as a maximum head. the efficiency could be near the 80 % for a hight flowrates.

- If possible expect a gas turbine engine as prime mover.

- Assume a liquide velocity about (5+D/3)ft/s and a pressure drop about 2psi/100ft at pump discharge

- Assume a liquide velocity about (1.3 + D/6) ft/s and pressure drop about 0.4 psi/100 ft

- All The SDV shoul be a ball valves in the discharge side.

- The discharge control valve should be a globe or a butterfly with an equal percentage characteristic

Moreover, you must think so more about the operational procedures of the piping system and the pumping plant........

**D it's the pipe diameter in inch.

Good luck.
