	We have a proposal to drive the remaining oil in the pipe by using the compressor from the inlet to the outlet pipe, the pipe runs for about 40,000 meters long..the pressure needed is 650 psi..pls help me to compute for the power needed by the compressor to drive the remaining bunker C, also do you think our proposal of using compressor is efficient enough to pump out the oil, do you have other suggestions..thank you very much!

	If there are traps (low spots) in the pipeline, the oil could pool there while the air blows over the top. You may need to provide drains at all these traps, which could be manifolded into a small auxiliary pipeline. This is just an idea. It would be interesting to know the elevation profile of the main pipeline. __________________ In vino veritas; in cervisia carmen; in aqua E. coli.

	What is the diameter of the pipe? Is it the same diameter all the way? Are there any sharp 45 or 90 degree turns in the pipe? What will the back pressure be? I suspect your endeavour is destined to fail. The compressed air, will find a way through or over the crude oil as air is not as dense as the crude oil and will probably not do as you want. If there are no impediments in the pipeline you may be able to push the crude using a "pig" or solid sabot by pumping water in behind the "pig". When the pig arrives at the end of its 40 Km journey you know that you have decanted all the crude. You could use air pressure but it would take a lot of CFM to make that happen. __________________ There are two reasons for a man to do a thing, One that sounds good, and the real one...

	The pigging plan is excellent, if the pipeline geometry and interior finish permit it. GA. __________________ In vino veritas; in cervisia carmen; in aqua E. coli.
