LPG Liquid expansion turbine??

LPG Liquid expansion turbine??

LPG Liquid expansion turbine??

(OP)
We are operating cross country LPG pipeline system.
We have PRV, to reduce the pressure of LPG from 20 Kg/cm2 to 9 kg/cm2. But i feel that we can replace the PRV with Turbine expander, which will letdown the pr & produce electricity.

Does my idea work...?
Can someone help me in turbineexpander for LPG...?
If you came across such a system, the do give me the details.

RE: LPG Liquid expansion turbine??

It is called liquid expander and quite a common equipment now in modern LNG plant. As far as I know Flowserve and Ebara Cryodynamic are in the market.

Thank you.

RE: LPG Liquid expansion turbine??

lets say you had a BIG pipeline moving 100,000 bbls per day of LPG (95% purity propane).  Given your conditions you might get 150KW worth say $250 US per day.  The system that big would cost a million or more US dollars.

It would also need 10 to 15 KW of power to run the oil pumps and coolers.
