Producing a drop-in gasoline product and on-site power from stranded or low-value natural gas resources

GTI's partial oxidation gas turbine (POGT) technology is being developed as part of a GTL process. Under ARPA-E funding, GTI collaborated with Aerojet Rocketdyne to test a high-temperature, high-pressure natural gas partial oxidation reactor that would be combined with an advanced turbo-expander being designed for this application. Systems testing was performed on the reactor and the entire GTL system underwent an economic evaluation.

Because the method produces both power and liquid fuel, it is an attractive option for associated gas now flared in oil production fields (including offshore platforms). In addition, the economic assessments also suggest that it has promise in other applications where power off-take is available. The amount of co-produced power can be controlled, allowing for flexibility as electricity demands change. Modular equipment will allow the size of the process plant to be tailored to match the amount of natural gas at the on-site location, minimizing the plant footprint.​
