Unconventional drilling techniques have unlocked vast reserves of gas, but getting the gas to market remains a challenge due to limited pipeline capacity. An alternative monetization option is to convert the gas into a valuable liquid, such as gasoline or methanol, bypassing the need for pipeline transport. Historically, gas-to-liquids (GTL) systems have only been implemented at large scales, such as the 1.6 BCF/D Pearl plant in Qatar. However, recent advances in process design and cost reduction have resulted in small-scale GTL systems profitable at gas flows of 4-20 MMSCF/D. Small-scale GTL units based on STG+ technology are now an attractive option for gas processors and producers achieve gas monetization in an environment with limited pipeline capacity. The Primus STG+ technology converts natural gas to gasoline through a proprietary catalytic thermochemical process, producing a single finished product, offering simplicity and lower cost when compared to Fischer Tropsch based systems, which produce a large variety of hydrocarbons requiring costly refining, alkylation, storage, and meeting multiple product specs.
