pipeline pressure drop and sizing

pipeline pressure drop and sizing

(OP)
I have a problem with pipeline pressure drop calculation. the fluid is sour gas, input pressure is 2.5 bara and output must be 1.5 bara; but cosidering pressure drop due to pipe , 2 control valves and 1 flow orifice, loss is more than 1 bar. could you help me with this problem?
Thanks in advance.

RE: pipeline pressure drop and sizing

You need to look at the pressure drops through the control valve, the meter and the pipeline.  If this is a new system, all can be adjusted (to some extent, you need a certain dP through the control valve to have a stable control system).  If it's an existing piping system, your first thing to look at are changing the control valves and meter so they take less of a pressure drop.

Note, there may not be a solution if the pressure losses through the pipeline by itself are close to much less greater than the 1 bar you have allocated.  

At that point, you need to consider raising the inlet pressure, lowering the outlet pressure, looping the pipeline (putting another one in parallel), lowering the flow rate or just accepting some things are not meant to be
