LNG Processing & Power Generation

LNG Processing & Power Generation

LNG Processing & Power Generation

Hello Everyone,

This is my first post, hopefully I'm within the right area. If I'm not, I apologize and ask for your redirection.

Currently, I am completing a bottom up estimate for a small LNG Regas Facility. This facility will be recieving LNG for the sole purpose of producing electricity only. The gas will not be sold to a consumer in any other forms other than electricity. So, once the LNG has been recieved and regassed it will be used to Fuel a Combined Cycle Gas Tourbine. My question is this. In order to use the gas as a fuel would it need to be processed first? or can combined cycle tourbines handle "raw gas". It be great if someone could give me an answere maybe even with some reference material.

Thanks everyone for your time & input.



RE: LNG Processing & Power Generation

First, you have to give your "raw gas" composition to your turbine vendor to see if they can burn it.  When you say "raw gas" and mention the need to process it, I assume it is liquified as it comes out of the gas field and not processed prior to liquifaction.

If that is the case, then the turbine manufacturer's fuels team will have to evaluate what is in that gas with respect to their turbine's ability to burn it, and their turbine's materials ability to survive whatever is in the gas.

If the gas passes muster with the turbine manufacturer, then also let the HRSG manufacturer know what is in the gas so that they can evaluate the materials used in the bottoming cycle.

Excellent points, thank you... this certainly provides me with direction.

Much appreciated.

Many gas turbines has a FG pressure above the dew P (at ambient temperature) of LPG (e.g. around 20 barg).

So the LPG may be a liquid fuel?

Best regards
