J Curves (HP vs. Gas Velocity)
J Curves (HP vs. Gas Velocity)
(OP)
We are in the "planning" phase and have rough numbers generated for flows on our pipeline segment however one question is being bandied about; at what point are you simply paying too much for each additional HP to generate additional volume's of flow. I have found numerous references to corrosion at high gas velocities and API references to max velocity etc however we have very clean gas and I am not concerned with this. Does anyone know if there is a reference to a max gas velocity (for efficiency or economics)in spacing of compressor stations?





RE: J Curves (HP vs. Gas Velocity)
errosional velocies for clean gas are huge, in the 100's of feet per second. most gas lines are designed for under 15 ft/sec.

here is a page from a book I googled up with a chart on spacing.
