Primus and Jereh will jointly market and deploy a range of flexible, robust GTL systems—including gas-to-gasoline and gas-to-methanol systems—that use Primus’ proprietary STG+ process to produce high-quality liquid products from natural gas. The technology economically transforms natural gas feedstocks into liquid end products at scales as small as 4 MMscf per day (100,000 Nm³ per day) of natural gas.

The STG+ technology can use a range of natural gas feedstocks, including wellhead and pipeline gas, dry or wet associated gas, “stranded” ethane, excess syngas from underutilized reformers or mixed natural gas liquids. The systems’ stranded and associated gas applications offer a solution to the lack of traditional natural gas pipeline infrastructure in remote locations, enabling the monetization of gas that would otherwise be stranded or flared.

The low-sulfur, zero-benzene gasoline produced through the STG+ process can be sold into a refinery blending pool or directly into the wholesale market. Methanol produced through the GTL systems can be sold into regional markets or used onsite in oil and gas production operations, where it functions as a corrosion or scale inhibitor, a friction reducer, inhibitor of hydrate formation and a fracturing fluid flowback enhancer.

The pre-engineered, modular units are fabricated offsite, then transported to the project site for final assembly, enabling rapid delivery and expedited construction time.

Primus’ process has been validated through more than 7,000 hours of operation at its commercial testing plant in Hillsborough, N.J. Compared to other GTL technologies, Primus’ STG+ process offers low capital and operating costs, high liquid product quality, zero wastewater, and process simplicity. STG+ technology can be economical at all scales, starting as small as 100,000 Nm³ per day of feed gas.
