As you may be aware, ~$20B of gas is flared each year around the world. Globally, flaring produces approximately 400 million tons of harmful greenhouse gas (GHG) emissions annually, according to the World Bank-led Global Gas Flaring Reduction Partnership. This flaring often occurs in remote oilfield locations, where limited to no pipeline infrastructure exists to transport the gas to market. This challenge represents a huge opportunity for small-scale GTL – New technologies that enable the deployment of cost-effective, small-scale gas-to-liquids plants can help oil and gas producers capture the flared gas on-site and monetize the resources currently being wasted.
Primus is an alternative fuel technology company that has developed a proprietary STG+ gas-to-liquid technology poised to solve some problems the oil and gas industries are facing. They have so far:
- A 100,000 gallon/year demo facility in operation, which is producing 93-octane gasoline directly from natural gas. (meets regulatory standards in U.S. and Europe. Here’s a link to animation explaining STG+
- Their 93-octane gasoline produces less CO2, low in benzene, and zero sulfur, compared to traditional gasoline, and the Primus product can be mixed with traditional gasoline.
In most cases, flaring is the only option for oilfield operators, as pipeline infrastructure doesn’t exist to get the gas to market. That’s where Primus comes in. Earlier this summer, Primus introduced the commercialization aspects of their flared gas solution. The system takes natural gas that would otherwise be flared and converts it into high quality gasoline using Primus’ proprietary STG+ technology. The gasoline can then be blended into a refinery gasoline pool or mixed with crude for simplified transport. Since then , they have been approached by numerous oil and gas producers from around the globe who are eager for an economic alternative to flaring in the face of increasing anti-flaring regulations.
The flared gas solution modular systems are available in standard pre-engineered models with nameplate production capacities of 250, 500, and up to 2000 BPD. In the future, these systems will also be available for offshore applications. The technology is a significant improvement over other on-site platforms being explored – which include CNG technologies and other, less cost-effective GTL technologies – as it can produce multiple end products from the same gas feedstock. The Primus process also is less water intense and has the ability to recycle water.
