"Positive" pressure assurance in pumping systems.
"Positive" pressure assurance in pumping systems.
(OP)
Dear friend,
My query may seem quite inane but I would like you to advise me on how to assure that a pipeline operates always in a "positive" pressure at the highest elevation point and the liquid colume doesn't split even if pumps provide sufficient head. For example I'm trying to pump an amount of product from a higher elevation point to a lower,with a pipeline profile that followes ground elevation that forms a high point. Do I have to foresee a back pressure control loop? How can I achieve that?
Thanks in advance.

If its multiproduct line, don't ever let the vapor pressure go low when an interface is transiting. What a mess that can make.
