Greyrock’s DFP™ systems convert natural gas directly into liquid fuels including clean, premium diesel. The Flare-to-Fuels system converts gas that is routinely flared into clean fuels that can either be blended with crude (on site, at the well pad) or used as finished fuels.
Natural gas is flared when during oil production associated gas is produced from the reservoir together with the oil. Due to unavailability of pipelines or other economical methods of utilization of the gas, this associated gas may be flared. Flaring of gas produces CO2, NOx, black carbon, and other pollutants. Improperly operated flares can also vent substantial amounts of methane, a strong greenhouse gas. An estimated 66% of the black carbon emissions in the Arctic is a result of flaring.
In addition to flaring being a major environmental issue, flaring wastes a valuable energy resource. The WorldBank estimates that approximately 5 trillion cubic feet of natural gas is flared every year, causing about 300 million tons of CO2 to be emitted into the atmosphere causing the same climate impact as 77 million cars per year.
Greyrock Flare-to-Fuels systems are designed to locate at the well pad and produce clean liquid fuels from flare gas. Fuels produced from the Greyrock system can either be blended with oil at the well pad or processed further to produce specification, premium diesel fuel.
