The GTL process
The gas-to-liquids (GTL) involves three processes:
The final products include ultra-clean, premium diesel, kerosene (jet fuel), naphtha, bases for synthetic lubricants and waxes. Products of the FT process offer significantly better performance and lower harmful emissions than their petroleum-based equivalents.
Conventional GTL versus smaller scale GTL
In conventional GTL plants the FT process is carried out in very large fixed-bed or slurry-bed reactors. These are designed to work on a very large scale. They require a capital investment of $3 billion or more, and are only economically viable for plants producing at least 30,000 barrels per day (bpd). Only about 6% of the world's known gas fields are large enough to sustain a GTL plant of this size.
Smaller scale GTL, enabled by Velocys technology, provides a cost-effective way to take advantage of smaller scale and remote gas resources. Our technology makes it possible to build GTL plants that process 150 – 1,500 million m3 per year (15 – 150 million cubic feet per day) of gas, producing 1,500 – 15,000 bpd of liquid fuels. Velocys' GTL technology makes smaller scale GTL possible due to the combination of our microchannel reactors and our super-active catalysts that together, intensify the FT process. This leads to better product yields and economics, and a plant that is easy to deploy at smaller scale.
