Gas-To-Gasoline (GTG) Plant Completed, Turkmenistan


RHI has successfully completed the world’s largest Gas-to-Gasoline (GTG) plant for State Concern Turkmengas, Turkmenistan’s state-owned gas company, headquartered in Ashgabat, together with our partner Kawasaki Heavy Industries, of Japan. The EPC contract was signed in August 2014 and the construction of the project took about four years, executed by an international team of about 7,000 people.

The GTG plant is located in the Ovadan-Depe area, on the north side of Turkmenistan’s capital, Ashgabat. Kawasaki assumed responsibility for overall project supervision and control, plant engineering, and equipment supply. Kawasaki also cooperated with the Sojitz Corporation on project implementation.

The plant employs an advanced technology developed by Haldor Topsoe, a Danish company providing chemical process technologies and catalysts. It is the only plant of its kind worldwide that produces 600,000 tons annually of high-quality gasoline from natural gas.

At this plant, gasoline is produced from methanol synthesized from natural gas. The gasoline produced contains no heavy metals, so no toxic substances are emitted during its combustion. Moreover, because the gasoline is 100% chemically synthesized from natural gas, it contains only small amounts of sulfur and other impurities and thus meets strict environmental standards in countries around the world.
