Flushing a Hydrocarbon Line
Flushing a Hydrocarbon Line
(OP)
I want to flush one hydrocarbon product out of a line with another hydrocarbon product. I need to calculate how much of the second fluid is required to flush out the first fluid down to 0.01 vol% (amount of first fluid left in the pipe) in a 26" line (4 miles long).
I have found the "power velocity distribution law" equation. Has anybody had any experience using this in this type of application? Does anybody have any suggestions for solving this type of problem?
Thanks.

We are, unfortunately, limited in our flow rate.
I'm interested in the Austin-Palfry equations, but I have been unable to find them. Can you help me out with that? Are they available in a document somewhere online?
Thanks.

What's the products?
I haven't found Austin-Palfry equations online. Austin-Palfry method is the most well-known, but I use some Exxon interface generation equations which similar results and I have more complete documents on it. I can send those to you if you drop me an e-mail. See my web page for the address.

4 miles + Turbulent flow sounds like high pressure drop. just to fill a experience gap:
Does longer pipelines (3-15 miles) operate at turbulent flow?
Are this kind of pipes typically mechanically calculated for this?
Kind Regards
