forcing gas flow through the branch line
forcing gas flow through the branch line
(OP)
Hello , I'm working on a gas plant and there's a place where there's a main gas header and then there's a branch line that takes off from the main header which is the same size as the main header but only 30% flow is required to go through the branch line and 70% through the main header. Would putting an orifice in the main line upstream of the branch can force 30% through branch . Please let me know the engineering behind it and the orifice sizing .

If the end point pressure is the same for both lines and the distances the same then you would have expected the orifice to be on the branch line.
Your question makes no sense without data (size, pressure, flow etc) and drawings / sketches of the system.

If the only orifices available, verify how many flow conditions you may excepted in the system, in terms of flow, P&T, etc., and calculate the orifice size as needed for each case. And then, you may use the proper orifice under the specific flow condition as required.

This is where a diagram helps a lot.
