EIA’s International Energy Outlook 2017 (IEO2017) projects that liquids constructed during gas-to-liquids (GTL) plants will boost as dual large-scale projects are finished in South Africa and Uzbekistan. Most of a new GTL ability will come from a acclimatisation of Sasol’s coal-to-liquids plant in Secunda, South Africa, to a GTL facility. That acclimatisation is approaching to be finished by 2024. A formerly behind GTL trickery in Uzbekistan is also approaching to come online by 2021.
Gas-to-liquids technologies typically use the Fischer-Tropsch Process to modify healthy gas to petroleum products. The ensuing products embody diesel and gasoline, as good as waxes. EIA estimates tellurian prolongation from GTL comforts now averages about 230,000 barrels per day (b/d), or about 0.2% of tellurian liquids production. As of a commencement of 2017, some-more than 90% of this GTL prolongation comes from 4 projects: dual in Qatar, one in South Africa, and one in Nigeria.
In a IEO2017 Reference case, EIA does not design any other large-scale GTL plants to be built or stretched by 2040. Large GTL plants are collateral intensive, and their economics count on a cost of wanton oil relations to healthy gas. Some countries with GTL comforts miss domestic oil resources though have entrance to healthy gas. GTL plants concede these countries to modify healthy gas to petroleum products.
Many formerly designed expansions of existent GTL comforts have been put on hold, and additional expansions are not approaching underneath projected marketplace conditions. Aside from a South Africa and Uzbekistan projects, EIA expects a remaining expansion in GTL outlay to come from comparatively tiny facilities, any with a ability of 5,000 b/d or less.
Small GTL comforts can be modular, with prefabricated routine units that are shipped to plan sites and related together instead of being built from a belligerent adult in a field. Modular plants can be shipped and fabricated in healthy gas-producing regions with deficient infrastructure to ride healthy gas.
Some of these projects might also include microchannel reactors that use tiny reactors to modify healthy gas to liquids some-more well though extent a altogether throughput of a facility. Small-scale GTL projects can revoke flared healthy gas from in-field prolongation and emissions from landfills. Production from small-scale GTL plants is not a poignant writer to volumes of petroleum liquids in EIA’s IEO2017 Reference case.
In a IEO2017 High Oil Price case, universe wanton oil prices are insincere to be most aloft than in a IEO2017 Reference case, that provides an inducement to erect new GTL plants or supplement ability during existent plants. In a High Oil Price case, tellurian GTL prolongation continues to boost from 2025 by 2040. In a Low Oil Price case, a Uzbekistan plan is still insincere to come online, though no other projects (including a South Africa plant) come online after 2021.
