QUESTION FOR OIL/GAS ENGINEERS

QUESTION FOR OIL/GAS ENGINEERS

(OP)
Good Day ! Fellow engineers I would need your help regarding a LPG pipeline system.
The existing line pressure is 10psi in the main LP gasline and I am ask to design a system in which the pressure requirement is 15psi. Is it possible to install a HP regulator which will convert 10psi to 15psi?
Thanks.

RE: QUESTION FOR OIL/GAS ENGINEERS

No.

You need a pump to convert 10 psig to 15 psig. Energy in x pump efficiency = useful energy out, remember?

Now, if you ORIGINAL "pump" (pressurized source of the LPG) was continuously HIGHER than 15 psig,
AND your 10 psig pipeline pressure was "regulated" or reduced down to 10 psig prior to entering the pipeline,
AND the pipeline
AND ALL of its systems were rated for service at 15 psig after a lifetime of use, then you "might" be able to re-set that pressure regulator (reducer) up to 15 psig output and subsequently operate your pipeline at 15 psig.
