Use of natural gas condensate as fuel for power generation gas turbines

Use of natural gas condensate as fuel for power generation gas turbines

Use of natural gas condensate as fuel for power generation gas turbines

(OP)
Hi all.

I am interested in solutions that can use natural gas condensates liquids produced by our gas plant as fuel for power power generation gas turbines.

The gas plants of interest are currently in operation and export up to 150million scf of gas per day and produce up to 10 thousand barrels of condensate daily,which is exported via a pipeline.However,when the export pipeline is unavailable the gas plant gets shutdown.

I am thus looking for a solution that can use the produced condensate liquid as fuel to generate power from a gas turbine on site so as to reduce dependence on the export pipeline.

Kindly advise what solutions are available for the volume of condensate stated above.

Regards,
Thony

RE: Use of natural gas condensate as fuel for power generation gas turbines

NGL usually commands a good price in the market as petrochemical feedstock, and it would be a crime to use it as a fuel - better to install additional storage to account for say the duration equivalent to the 80% cutoff of export pipeline shutdowns.

You may be able to see the economics of this and see how long it takes to pay off the incremental CAPEX for the additional storage.

Also, check with the turbine manufacturer if they can add on the additional nozzles for liquid fuel combustion also ( dual fuel operation) - this also needs to be accounted for in the investment decision. If these are low NOx turbines, more complications.

API 650 tanks may be okay for 8-10 TVP stabilised condensate, but you may need to go up to API620 if vapor recovery is indicated by your company for this event.
